YouTube Codecs Explained

If you’re new to the wide and wonderful world of YouTube—or working with any kind of video for that matter—you might have heard of video codecs.

Or perhaps you’re not so new, and you’ve heard of them, but you don’t really understand what they are or what they do. If you are either of these people, this post is for you.

Video codecs are the software and method that is used to compress video. In the case of YouTube, codecs are employed to reduce the size of the video before it is streamed by millions of people across the globe.

It is an essential part of transmitting video, and there are a variety of different flavours available. But what are they? And why are they so important? Read on to have YouTube codecs explained in full.

What is a Codec?

In short, codecs are compression. They are the software and method used to compress a large video file into a smaller video file using clever algorithms that strive to achieve the most significant reduction in size at the expense of as little loss of detail as possible.

Video is an incredibly large medium in terms of raw data—which we’ll get to shortly—and few people who don’t work with video appreciate just how much information is involved. Of course, anyone who edits video in any capacity will be fully aware, and anyone who has ever attempted to edit 4K video on a computer that, while powerful, was nevertheless not up to the task, will appreciate the struggle that video can present.

If you need help in deciding between 1080p and 4K – maybe you are lost and don’t know the difference – check out my deep dive blog on 4K and it could take YouTube by storm!

Codecs don’t typically help with editing, however, but they make life a lot easier on your Internet connection, and given how far our Internet speeds have come in recent years, the fact that there are still effort to improve compression and shrink video files further should serve to highlight how big video can be.

How do Codecs Work?

In the simplest terms, codecs compress information into a smaller size by replacing it with a different set of data that represents the original information.

To give a very simplified example of this, imagine you have a still frame of 1080p video where the top half of the screen is entirely black. Each pixel on the screen has to be accounted for in the data for that still frame, which means there are 1920×540, or 1,036,800 pixels. That’s a lot of data.

However, we don’t need to store every single pixel in our data. Knowing that the next million pixels are the same, we can just say that and be done. Saving the data equivalent of “Black: 1,036,800 times” is a lot more efficient than actually listing black over a million times.

Of course, there is much more to it than that, but it should serve to give you a basic grounding in how codecs do their job. Compression can be taken to extreme levels, of course. Video can be compressed until it is little more than a pixellated blur of what it once was—albeit is a pixellated blur that takes up considerably less space than it once did. Many ingenious techniques are employed to preserve information, but as a general rule, the more compressed a video is, the more of that original information you lose.

“Why is information lost?” we hear you asking. In the above example of a frame that is half black, no information would be lost. The entirety of that black half of the screen would be stored fully intact in the dramatically reduced space we outlined. Real-world applications of compression are not so simple, however.

There are very rarely large portions of a frame that are the same colour in a frame of video, especially a film or TV show. Furthermore, there may not be any smaller areas that are identical. When you consider the depth of colours available and things like film grain, it is entirely possible to have frames of video where there isn’t a single collection of pixels adjacent to each other that are identical. In those cases, the simple compression method we detailed above would be useless.

This is where the information loss comes in. Codecs employ algorithms to decide what is compressible. If you have two pixels that are ever so slightly different shades of blue, they would technically be different but probably not different enough that the human eye could distinguish between the two.

The compression algorithm may count both of these pixels as the same colour, allowing it to reduce the size of the frame slightly.

And, when the video is decoded, it will still look good to our human eyes, but the information of that slightly differently shaded blue pixel is lost, and cannot be recovered from the encoded video.

This is why high-resolution footage with a lot of film grain is hard to compress, because you either can’t get much of a size reduction from the compression, or you lose a lot of that fine detail.

This should hopefully also go some way to explaining why there are so many codecs available. It is not a simple matter of which codec reduces the video size the most, there are preferences to take into account.

Some codecs are more aggressive, others don’t achieve the same degree of size-reduction. Depending on what you are doing with your video, different codecs may be suitable.

Should I Upload 4K to YouTube? 2

Why do we Need Codecs?

Computers are getting more powerful, and Internet speeds are getting faster, but at the same time, media is growing in fidelity.

There was a time not too long ago when our only means of watching video was the equivalent of a 640×480 screen, in what would retroactively be called 480i. For comparison, 1080p—which is considered the bare minimum these days and is even drifting slowly into obsolesce—is 1920×1080. That’s three times more information than the standard definition video we used to watch.

In keeping with this trend, 4K—which is well on its way to replacing 1080p as the defacto standard—is four times larger again. It should be noted that the “4” in 4K is not down to the fact that it is four times the size of 1080p, but rather the fact that the horizontal resolution is nearly 4,000 pixels across.

But 4K itself already has a replacement on the horizon, with 8K screens creeping onto the market. As you might have guessed, 8K is four times larger again than 4K, though we are far from 8K being commonplace in our homes, so we wouldn’t hold off on purchasing that 4K television just yet.

So what does all this mean? It means that despite computers getting more powerful and Internet speeds getting faster, the size of the media we are trying to play is getting similarly more substantial. Exponentially so, in fact. And this is just taking video files into account; there is also game streaming to consider, which Google is getting into in the form of their Stadia service.

And, while this is a gaming platform, it ultimately boils down to streaming live video to your screen, and will likely be a big part of YouTube if it succeeds.

Should I Upload 4K to YouTube? 1 Two players playing video games on TV at home

To illustrate this point, here is a list of some resolutions and their typical data rate in megabits per second (Mbps). This is the amount of data that is being transmitted per second, whether that is from a Blu-ray drive to your screen, or from a distant server and over the Internet.

 

Compression Type Resolution Bitrate
YouTube @ 60FPS 1080p 4.5-9 Mbps
Blu-ray 1080p 20-30 Mbps
H.264 50Mbps 1080p 50 Mbps
No Compression 1080p 3,000 Mbps
YouTube @ 60FPS 4K 20-51 Mbps
X264 Codec 4K 100 Mbps
Blu-ray 4K 82-128 Mbps
No Compression 4K 10,000 Mbps

We should mention that all of the above compression methods are to a degree where the video is still kept to a high quality.

Of course, it would be possible to significantly reduce the bitrate further with more compression, but that would compromise the quality of the video to the point where it would affect the viewing experience.

Hopefully, that table will illustrate the importance of codecs. Even looking at the raw, uncompressed 1080p bitrate, it is sixty times more data than the typical bitrate that 4K video streamed over YouTube requires. Bearing in mind that 8Mbps is equivalent to 1 megabyte per second, a raw, uncompressed 4K stream would require data transfer rates of over a gigabyte per second.

This would present serious problems for Internet delivery, optical bandwidth in disc drives, and even if you were pulling the information directly from a high-speed solid-state drive, your computer would still need to be up to the task of processing that much information.

Audio Codecs

We’ve been focused on video codecs so far, but the audio is a critical part of the process as well, and the two do not necessarily go together in the compression process. When you encode video, the file name at the end (often .MP4) is little more than a wrapper. For the most part, you can mix and match your video and audio codecs to suit your needs.

As for the audio codecs themselves, there are nuances to compressing audio that differ from video, of course. For one thing, the smaller size of audio means that audio bitrates are typically measured in kilobits per second (Kbps) rather than megabits per second (Mbps).

But the broad strokes are the same as video codecs. They work to reduce the size of the audio by compressing it, often at the cost of some of the information stored.

The Best Codecs For YouTube

The answer what the best codecs for YouTube are is quite a short one since YouTube themselves openly tell us. YouTube prefer you to upload your videos in MP4 format, encoded with the H.264 video codec and AAC audio codec.

As we mentioned above, the file format and the codec are two different things, and YouTube is open to several different formats, such as MOV, AVI, MP4, WMV, MPEG, WebM, 3GPP, and FLV.

What Happens When I Upload Video to YouTube?

If you are already uploading videos to YouTube, you will be familiar with the “processing” phase of the upload process. During this time, YouTube is converting your video to a number of different resolutions.

When you select a different quality in a video—or when YouTube changes the quality automatically due to bandwidth issues—YouTube is not doing that on the fly. All the available quality options on a video are pre-processed and exist as their own video files on the YouTube servers.

Obviously, the capability to upscale your video to higher resolutions than the one you uploaded does not yet exist to the degree that would be feasible to use in this manner, but YouTube will create lower resolution alternatives. The standard definition is typically the first one to be created, though we would generally advise waiting until at least the high definition option has finished encoding, as that will be the most in-demand version.

YouTube has a preference for the codec you upload your video with because the fewer incoming codecs they have to deal with, the more they can optimise their platform and reduce the time it takes to process new video.

If you need help in getting the best setting to render out your video in 4K I have a blog dedicated to everything you need to know for 4K perfect quality, smallest file size and fastest upload times!

Are Codecs Free?

Not all codecs are free; however, the most popular ones that are used today do not cost money to use. While we are on the subject of free codecs, it is worth pointing out that codecs can be dangerous in the same way that downloading an executable file from an untrustworthy source can be.

Codecs can be used to get malicious software onto your computer, or they could just cause serious problems when attempting to playback media. So take care when downloading them, and make sure you are downloading from a verified source.

Summing Up

So, now you have had YouTube codecs explained, why you need them, and how they work (in simplified terms).

Remember, the world of codecs is not static, and new developments happen all the time, especially with new video formats and resolutions popping up from time to time.

It’s worth checking in with YouTube’s help resources occasionally to make sure there haven’t been any developments you should know about.

How To Record 4K 60 FPS Video on Your Mobile (iPhone and iOS Devices)

So you want to record in 4K and you want to do it on your mobile phone at 60 FPS.

 

You don’t have to have a DSLR nowadays. You don’t have to have a powerful, stupid webcam. You can record fantastic footage, even in 4K on your mobile phone.

 

How To Record 4K 60 FPS Video on Your Mobile (iPhone & iOS Devices)

 

Now, most people will be focusing on 1080p right now, and there’s no real difference in uploading to 4K just yet, but maybe you want to get ahead of the curve. Maybe you want to record at 60 FPS to slow it down at certain points.

 

I get that 4K video can be confusing – I have deep dived into 4K vs 1080p for YouTube in my blog. We look at resolution, bit rate and even look into whether is does better on YouTube in search.

 

I’m going to show you how to do it on this phone.

Alan Spicer - YouTube Certified Expert

Now you get out your phone, you hit the “Settings” menu and you scroll all the way down to “Camera.”

How To Record 4K 60 FPS Video on Your Mobile (iPhone & iOS Devices)

In here, you’ll see your QR code settings, your grid, whether you’re recording in HDR or whether you’re recording in Slow-mo.

 

But the most important setting is your video record and mine is currently set to 1080p at 30 frames per second.

How To Record 4K 60 FPS Video on Your Mobile (iPhone & iOS Devices)

But as you click through, you’ve got a choice of settings here: 720 at 30, 1080 at 30, 1080 at 60, 4K at 24, which is normal for talking heads. Then 4K at 30 frames per second, which is normal if you’re just chatting like this, and 4K at 60 frames per second, most efficient.

How To Record 4K 60 FPS Video on Your Mobile (iPhone & iOS Devices)

Now you’ll also see on the screen that it will break down roughly what this means to you.

 

You’re looking at 720 if you’re going for small file sizes, 1080p at 60 frames per second if you’re looking for normal and smooth video.

How To Record 4K 60 FPS Video on Your Mobile (iPhone & iOS Devices)

4K at 24 frames per second is the movie look, and 4K at 60 frames per second, it gives you more leeway, a little bit more flexibility, the ability to slow the footage down if you need to.

 

Why do you want to slow it down?

 

Well, the human eye is used to seeing things in cinemas and on games at 24 or 30 frames per second, these are the things that you normally see on TV. 60 frames per second is what you’re used to maybe on PC and stuff like that and 60 frames per second gives you the chance to do slightly slow movie shots.

 

But if you really want to go for slow-mo, try 240 frames per second on the iPhone. I’ve done a video here and if it’s not there quite yet, I’ll add a link in the description when it arrives.

YouTube 4K Vs 1080p

In what might seem like something of a contradiction, 1080p has, for a few years now, been considered both the bare minimum and the peak of quality for YouTube videos. Brought about mainly by the plummeting costs of hardware capable of recording in 1080p, it is generally considered inexcusable to upload a video at a lower resolution.

But at the same time, so few people are viewing YouTube at a higher resolution than 1080p that it becomes impractical to move to something more.

But something more is on the table, of course. 4K video has arrived, and its popularity is growing. But how does 4K compare to our old friend, 1080p? And what does it mean for the future of YouTube?

Should I Upload 4K to YouTube? 2

What is Resolution?

Let’s start with a crash course in the basics. Both 1080p and 4K are resolutions. Resolution—in the context of displays, such as your phone screen, or computer monitor—is the number of pixels that screen can fit. A pixel is a tiny dot of light that represents the smallest thing that can be drawn on the screen.

The larger the resolution, the more detail you can fit on your screen. Think of it in terms of trying to create a picture using a fine pencil vs using a broad paintbrush, but both are on the same size canvas. You can get considerably more detail into your picture with a fine-tipped pencil.

1080p, also known as “Full HD”, has been the standard resolution for monitors and televisions for a number of years now, and we’ve come to expect it as a minimum. Many people who mostly grew up around 1080p are shocked the first time they see 480p—the resolution that televisions used to display.

4K, so-called because it has nearly 4,000 horizontal pixels (it also has exactly 4x the number of pixels as 1080p, but that is just a coincidence), is next standard that television manufacturers are hanging their hat on.

There are resolutions in between the two—2K is a thing, for example—but it is 4K that has been picked to succeed 1080p as the standard.

What is the Difference Between 1080p and 4K

Let’s start with the resolution since we’ve just explained what that is. 1080p is 1920×1080. That’s 1920 pixels across and 1080 pixels down, and it is the 1080 pixels down that gives this resolution its name. The “p” stands for “progressive scan”, which means all the horizontal lines of the pixels are drawn in sequence.

This an alternative to interlaced video, where every other line is drawn first followed by the remaining lines to give the impression of a higher framerate. Smaller resolutions are also labelled this way, with 720p and 480p being the main two resolutions below 1080p that you will find in televisions.

Let’s just briefly touch on aspect ratios. This is the relative size of the horizontal edge of the display vs the vertical. So for a 4:3 display, there will be four horizontal pixels for every three vertical pixels. This is relevant because it is possible to have a 1080p display that is considerably wider than 1920 pixels across. For the purposes of this post, however, we’re going to be referring to 16:9 aspect ratios unless otherwise stated, as that is the most common ratio found in televisions and monitors. Now, about 4K.

4K, on the other hand, is 3840×2160. If you’re wondering why it is not labelled 2160p, it’s purely a market thing. “4K” sounds cooler. There is a commonly used resolution (in PC monitors, not televisions) in between 1080p and 4K, which goes by both 1440p and 2K, depending on the mood of the person talking about it.

The numbers tend not to look too impressive when laid out as horizontal and vertical counts, but when you total up the number of pixels on screen, the difference is a little more apparent. A 1080p screen holds 2,073,600 pixels. That’s a lot of pixels. However, a 4K display holds 8,294,400 pixels.

That’s quite a difference.

In terms of direct differences, that’s about the start and end of it. However, there are further differences that come as a natural result of that difference in resolution. For one thing, the bandwidth needed to stream 4K content is considerably higher than that of 1080p, something that is particularly relevant when we’re talking about YouTube 4K Vs 1080p. The amount scales as you’d expect. Where 1080p requires somewhere between 8-12 Mbps to stream, 4K requires 40-70 Mbps. This is particularly important for the next section.

Another difference due to the increased size of the video is the computing power it takes to edit 4K content. Video editing is an intensive process at the best of times, and making that video 4x bigger requires a capable machine.

4K Compression

Compression is a complicated topic that would take a post the size of this one all of its own and probably still not do the subject matter justice.

To simplify it down to something we can fit in one section, it involves replacing repetitive information with more efficient ways of storing that information. For example, if the top row of pixels in a 4K picture is entirely black, that’s 3,840 pixels-worth of information, but each pixel is identical.

Rather than storing every single pixel, a compression algorithm might store data for the first of those pixels that include the colour, but then it would state how many pixels it repeats for. Using a simple method like this, the nearly 3,840 bytes-worth (1 byte per pixel) of information required for that top row of pixels could be reduced to something more like 24 bytes.

That’s 160x less memory being used to store the same amount of information!

Of course, when we’re talking about video footage, it’s not that common to get large areas of identical pixels, and as a result, the compression algorithms are far more complex than the example we just gave. Still, it helps to illustrate what is going on. But why is this relevant to YouTube?

Well, YouTube is in the bandwidth game, big time. In 2019, 500 hours of video were being uploaded to YouTube every minute, with over 250 million hours of video being watched every day. When you are dealing with that much bandwidth, even a tiny improvement in your compression algorithms can represent millions of dollars.

So, here’s the kicker. As you might have guessed from the woefully inadequate explanation of compression above, the busier a picture is, the less it can be compressed. In fact, if you had a frame of 4K video where every pixel was a different colour, it would be impossible to compress it without losing information. Now, 4K captures a lot of detail, and for the most part, a lot of that detail goes unnoticed. YouTube knows this, and so they tweak their compression algorithms to be a little more… keen.

If there is only a relatively small difference between two pixels, such as you might get from film grain, then it won’t make a noticeable difference to the video, but it could save an extra megabyte of bandwidth per frame. When you consider that a typical video will have at least 24 frames per second—with some videos being as high as 60 frames per second—you can see why YouTube might be willing to sacrifice a little of that detail.

Size Matters… With Your Screen

There is a thing called “pixel density” which refers to the number of pixels in a physical area and is measured in “pixels per inch”, or PPI. To understand what this represents in practice, imagine an iPad-like device with a 1080p resolution. Now consider a standard 21″ computer monitor with the same resolution.

Both devices are displaying the exact same number of pixels, but one of them is packing those pixels into a much smaller space. The higher the PPI, the more pixels there are crammed in, and the clearer the image looks.

There is a point, however, where pixel density becomes so great that the human eye is no longer capable of discerning the increased detail. This translates to a little over 300ppi. What that means, in practical terms, is that once you get above that threshold, there is no benefit to increasing it further, as our eyes literally cannot tell the difference.

As we’ve established, 4K has around 4x the number of pixels that 1080p has. This means that the critical pixel density we mentioned, where the human eye stops being able to tell the difference, is on a screen size of around 13″ for 4K, but is down to 6.5″ for 1080p.

What does this mean for YouTubers? Well, mobile phones—which often have screens between five and six inches—are the most popular way to consume YouTube content. That means that the majority of YouTube videos are watched on devices where there is no benefit to being in 4K since the viewer can’t tell the difference visually. Furthermore, only a tiny portion of computers running a 4K resolution are currently active on the Internet, meaning that of the people looking at a big enough screen to do 4K justice, the vast majority of them are not using a screen capable of displaying 4K content at all.

Recording 1080p Vs Recording 4K

What about recording video? By now, 1080p is ubiquitous in the sense that it is difficult to buy a device that doesn’t support 1080p.

Even budget webcams offer 1080p, and phones have long since moved beyond that barrier. 4K, on the other hand, may require you to buy a specific device (though you might already have one capable of recording in 4K).

It also requires more effort in setting up your recording space, more time spent encoding and uploading, and more power in your computer to edit that enormous video file.

YouTube 4K Vs 1080p

When you factor everything in, 4K begins to look like a lot of extra work for not much reward. Still, when comparing it to 1080p, there is little argument to be made against it in terms of quality.

While our eyes may have maxed out when it comes to mobile phone screens, computer monitors and TVs still have plenty of room to expand, and it is here where 4K YouTube content will make the most difference.

We can’t, in all seriousness, recommend that you take any difficult steps to move to 4K at this moment in time, but there will come a time when it is a necessary move. And, given that YouTube automatically scales video down to suit the device, there’s no downside to uploading 4K content if you can.

But if you can’t, and if you’re not thrilled about the idea of investing more time and money in your channel at this stage, don’t worry about it. 1080p will do just fine for now.

Should I Upload 4K to YouTube? 3

Maybe you are a youtuber and you want to know if uploading in 4K vs 1080p is better for YouTube? I have a deep dive into this and youll be surpised how much impact it could have on your views.

Finally, there is the issue of streaming. Internet speeds may be increasing all the time, but many homes don’t have a fast enough connection to stream 4K content, and certainly not at higher frame rates.

For reference, here are the different standard resolutions broken down.

Resolution Up to 30FPS Up to 60FPS
2160p (4k) 3840×2160 35-45 Mbps 53-68 Mbps
1440p (2k) 2560×1440 16 Mbps 24 Mbps
1080p (Full HD) 1920×1080 8 Mbps 12 Mbps
720p (Std HD) 1280×720 5 Mbps 7.5 Mbps
480p (DVD) 720×480 4 Mbps 4 Mbps

Conclusions

4K represents something of an inevitability for YouTubers. Even if the majority of viewers didn’t care, PC gaming and television sales are bringing 4K displays into the mainstream, and once people have 4K, they typically want to use it.

Whether this represents any kind of significant opportunity to find new subscribers through providing that 4K content at a time when there isn’t much of it will remain to be seen. But it is undoubtedly something of a unique feather for your cap.

As for switching to 4K, there’s no rush. If moving to 4K for you would be a frictionless affair, it is certainly worth doing. As mentioned above, YouTube will scale your videos down when needed, so the only reason not to go to 4K is the added costs and inconvenience to you. If those inconveniences don’t worry you, make the switch. You’ll be giving your channel a certain amount of prestige while also future-proofing your content for such a time when 4K does become the standard resolution. When this happens, you will not only be providing 4K content for your viewers, you will be established as a channel which provides 4K content.

And, when you’re all set up and producing stunning 4K content for your YouTube channel, you can begin planning for the next big thing—8K

Should I Upload 4K to YouTube?

As a general rule, the better the quality of your video, the better it is for your channel. While channels can—and indeed have—succeed with lower quality video, there is hardly any reason at all not to opt for the highest possible quality you can manage when considering things from a viewers perspective.

However…

As with most things in life, the practical reality of uploading videos in 4K isn’t quite as straightforward. 4K is nowhere near ubiquitous, yet the cost of a good 4K camera over a regular HD camera is not insignificant. The result of this being that you could end up putting considerably more time and effort into making your videos 4K, only to find none of your audience is watching in that resolution. But we want to go a little deeper than that, of course.

So let’s get to it. Should I upload 4k to YouTube? Kind of. If it is something you can already do—if you have a 4K camera, your set is nice and dressed up, you’ve mastered your makeup game, and you have a beefy Internet connection and a beefier computer, there’s no reason to not upload in 4K. If some or all of these things are not true, however, you need to weigh up the pros and cons before deciding 4K is for you.

What is 4K?

Let’s start with the basics. Before you decide whether 4K is right for your channel, you should know what it is you’re deciding about. 4K is a somewhat gimmicky name given to the latest standard screen resolution to hit the market. The name could come either from the fact that the horizontal resolution of 4K is almost 4,000 pixels or from the fact that there is exactly 4x the number of pixels in a 1080p display.

4K represents several challenges from a creator’s standpoint, from recording to editing and, ultimately, streaming. Not only do you need a camera capable of 4K, but it also needs to be a good camera, as poor quality video will be considerably more apparent at that resolution. You also need a computer capable of editing such high-resolution footage. As anyone who has rendered a video before can tell you; video editing is not light work.

You also need to pay more attention to yourself, your set, and anything that might be in the shot when filming. The increased resolution of 4K will bring a lot more detail into the light.

Finally, there is the issue of streaming. Internet speeds may be increasing all the time, but many homes don’t have a fast enough connection to stream 4K content, and certainly not at higher frame rates.

For reference, here are the different standard resolutions broken down.

Resolution Up to 30FPS Up to 60FPS
2160p (4k) 3840×2160 35-45 Mbps 53-68 Mbps
1440p (2k) 2560×1440 16 Mbps 24 Mbps
1080p (Full HD) 1920×1080 8 Mbps 12 Mbps
720p (Std HD) 1280×720 5 Mbps 7.5 Mbps
480p (DVD) 720×480 4 Mbps 4 Mbps
Of course, the average Internet connection speed in most developed countries has risen in the 100s, but it is important to remember that averages can be easily skewed by a relatively small number of abnormally high connections. And there is also the possibility that all of a households internet connection will not be available, such as would be the case if someone were watching Netflix at the same time your viewer is attempting to stream your 4K content.

One final thing to factor in is your connection. As fast as Internet speeds are getting, upload speeds have always been notoriously slow in comparison. Having to wait 4x as long for your video to upload (plus additional processing time at YouTube’s end) might not be an issue for you, but it’s worth mentioning.

4K Represents a Tiny Slice of the Market

Finding concrete statistics on 4K as it pertains to YouTube is not easy. What we can safely say is that only a tiny share of computer users online have their resolutions set to 4K. As shown by screenresolutions.org (at the time of writing), only 0.12% of users online are using 4K resolution, with 2K just creeping inside the top ten, and regular 1080p (1K, if you like) topping the list by a wide margin.

“But what about TVs?” I hear you yell. Well, more and more people are indeed watching YouTube through their TV, thanks to the prevalence of things like Amazon’s Fire Stick, Smart TVs and gaming consoles with an app ecosystem. However, 4K TVs are still vastly outnumbered by 1080p, so even if every TV owner on the planet was watching YouTube on their television rather than their computer, 4K would still be in the minority.

To briefly touch on phones since, of course, mobile devices are the most popular kind of device for watching YouTube on. While it is true that many—probably most—modern phones can display 4K videos, it’s something of a moot point since our feeble human eyes can’t tell the difference on screens that small. It is estimated that a healthy human eye can discern detail up to 326ppi (pixels per inch). 1080p on an average mobile phone screen is already higher than that, so increasing the pixel density further won’t make a noticeable difference.

4K is Growing

Now that we’ve talked about how small a market 4K is for YouTube let’s look to the future. 4K TV sales are increasing exponentially, and the ever-hungry PC gaming market is driving the sales of 4K monitors. Furthermore, the cost of making a 4K device is dropping to the point that the Smart TV Effect is beginning to take hold.

If you’ve never heard of the Smart TV Effect before… that’s because we just made it up, but the premise is simple enough. The “smart” part of smart TVs is notoriously terrible. There are exceptions, of course, but most smart TV interfaces are clunky, slow, and generally unpleasant to use. So why, then are they in almost every television?

The answer is because it got so cheap to add to their product that it was worth it just to get that “Smart TV” sticker on the box, it doesn’t matter if nobody wants a smart TV, it became almost impossible to buy one without it.

4K is heading in the same direction. The cost of making 4K TVs is dropping, which means the cost of the TVs themselves is dropping, too. 4K is proving to be a powerful marketing tool, if not a particularly useful feature given the lack of 4K content.

So what does all this mean for YouTubers? Well, 4K is a significant minority now, but it almost certainly won’t be staying that way. So when you consider whether or not you want to record your videos in 4K, you need to think about how important having the best possible quality is to your channel. Right now, 1080p is good enough, but 4K is coming.

So, now we have laid out all the basic information, how do you decide? We can get one straight forward answer out of the way easily enough. If you already have the means to record in 4K, and the thing you are recording is ready (remember, every imperfection, be it on you or your set, will be 4x larger), your computer is up to the task of editing, and the additional upload times do not bother you, then there is no reason not to upload in 4K.

YouTube will automatically process lower-resolution versions of your video, which will then be delivered to those who are not viewing on a 4K screen, so nothing will change for them. But you will be future-proofing your videos. Not to mention; with the lack of 4K content available right now, you may even gain viewers just through virtue of having 4K video on your channel.

But what about everyone else? What if you don’t have a means of recording 4K, or your computer wouldn’t be able to handle the editing even if you did? Is it worth taking steps to get 4K video?

This will depend on your channel. If you are making software tutorial videos, you shouldn’t be in too much of a rush to switch. The important thing there is clarity. If your viewers can see what it is you’re doing on screen, that’s good enough. If you can relatively easily switch to 4K, by all means, do it. If it’s going to be too difficult or expensive, don’t worry about it.

The same can be said for most types of channel, actually. For the most part, the benefits of moving to 4K right now are not big enough to warrant the cost and effort involved. But are there any types of channel where switching to 4K should be considered a priority? As a matter of fact, yes. Any channel where the viewing experience is paramount should consider getting onto 4K as soon as possible. This is as much for future-proofing your videos as it is for capturing current viewers. Videos like this tend to be evergreen—that is, they remain relevant long after they are uploaded. An example of such a video might be nature videos or aerial drone footage.

In two years, if somebody wants to watch “3 hours of serene woodland ambience”, they are not going to care if your video is two years old, but they might care if it is only available in 1080p when everything else is in 4K.

Tips When Switching to 4K

So you’ve decided that 4K is a good move for your channel? Great! Here are some things to think about.

Prepare Yourself

We’ve touched on it a little in this post. For better or worse, 4K video offers considerably more detail, which means your viewers will be able to make things out that they wouldn’t before.

If you like to look good on your stream, you might need to up your prep game. You should also take special care to make sure there is nothing in the shot that you don’t want public. This can include address labels, serial numbers, and any other potentially sensitive information.

You should do this anyway, of course, but the chances of a viewer being able to read the address on a label a few metres behind you in 1080p are pretty slim. Not so much with 4K.

Scale Up Your Text

This applies mostly to videos where text is a significant part of the content, such as with software tutorials. It’s important to remember that, while the resolution may be 4x larger than 1080p, the screens that your video is being viewed on are not.

Or, to put it another way, the same text that is legible on a 24″ 1080p screen will be 4x smaller on a 24″ 4K screen.

When you make the switch to 4K, you will need to rethink your various designs, such as end screens and lower thirds. Any text that would have been considered small in 1080p will need increasing in size when you switch to 4K.

Let People Know

If you are going to make the switch to 4K, be sure to let people know. This can be as simple as adding an “in 4K” to the end of your video title, and certainly tagging it and mentioning it in the description.

You will now be offering a type of content that is rare, so you want to capture that niche audience while you can.

Conclusions

The price of 4K equipment—both recording and watching—will continue to drop as it becomes more prevalent. There will come a time when the switch to 4K will not be as difficult as it is now.

That being said, there is an element of “getting in on the ground floor” about being a 4K YouTuber in 2020, and it could be a great way to gain extra subscribers that might not otherwise have checked out your channel.

Still, it is not a cheap transition to make. If that leap is too big for you at this moment in time, don’t sweat it. Most of us are watching in 1080p anyway.

Best 4K Video Settings for YouTube [Adobe Premiere Pro]

Faster, easier to worth with and smaller files in Adobe Premiere Pro with these 4K Export Settings! 

Today we are going to deep dive into what 4K video is, why it’s slowly replacing 1080p and what settings to use to make it painless to use!

Just because you’re shooting in 4K, that doesn’t mean you have to work in 4K. For many projects, 1080p is good enough.

The benefit of shooting in 4K is a quadrupled resolution, allowing you to zoom in cleanly since you have a much better source video to work with.

This is perfect for cutting to close-ups, effectively eliminating jump-cuts from your finished product entirely.

This effect can commonly be seen in single-camera interviews, where the perspective shifts between a wide full-body shot and a close-up shot of the interviewee talking. Pull it off well and it can be used for dramatic effect to add emphasis and connect better with the subject.

Even if your end product will be 1080p, shooting 4K will deliver a higher quality down-sampled image.

Capturing four times the amount of information you need won’t produce an image that’s four times better looking, but the end result will be noticeably sharper.

You’ll also reduce the chance of color banding, since most cameras record 4K at a higher bitrate. That means more color detail is captured, which will vastly improve gradual changes, like deep blue skies or other solid colors.

Sometimes the camera makes all the difference. Many modern mirrorless, digital SLR, and cinema cameras shoot 4K using larger sensors, effectively down-sampling a 6K or 8K image to 4K (like the relatively cheap Sony a6300, above). The Panasonic GH5 even does 6K video and 4K video at a bit-rate of 400 megabits-per-second.

Yes, there are many 1080p cameras that will shoot better HD footage than a cheap 4K camera.

What Is 4K? Do I need 4K Video?

We hear the word 4K every day in several places such as on youtube picture quality, gaming, in the specification of electronic devices like cameras, television, laptop, etc.

But what did this term mean? 4K means a digital resolution of approximately 4000 pixels; there are several different resolutions in 4K. 4K aka UHD (Ultra-high Definition), has a standard resolution as a 4K digital television of 3840*2160 with narrow borders, or 4096*2160 without borders – as popular in movies.

The picture quality of 4K content is very sharp, colorful, and professional; 4k quality enhances the user experience. It highlights every detail of the videos, let us have a quick eye on some of the advantages and disadvantages of 4K picture quality.

4K YouTube Videos vs 1080p YouTube Videos

4K is known as Ultra High Definition (UHD), whilst 1080P is simply labelled High Definition. As their names imply, 4K UHD has a considerably higher resolution than 1080P HD video. 4K resolution is exactly 3840 x 2160 pixels, whilst 1080P consists of 1920 x 1080 pixels.

The 4K designation refers to the close to 4000 horizontal pixels. Traditionally, resolution had been labelled according to vertical pixels and in the case of 1080P, 1080 vertical lines make up that high definition resolution. By comparison, 4K features 2160 pixels vertically; a considerable increase.

At an aspect ratio of 16:9, 4K contains almost four times the number of pixels on a screen compared with 1080P technology – more than eight million pixels for 4K and just two million pixels for 1080P.

This massive difference brings about some important advantages for 4K when one compares it to the quality of a 1080P video.
