bitrate, 4K, HDR10, Dolby Vision …

That your tv and the OTT that you’ve contracted have a label that claims 4K it doesn’t imply that the content material seems the identical in all of them. First, we now have to have a appropriate tv. The second, many platforms require a appropriate plan and never everybody permits the utmost decision, as is the case with Netflix. But not solely your tv or what you pay month to month relies on the picture high quality of the streaming platforms.

There are different components, past the 4K title, which refers to decision, that can point out the diploma of high quality of the picture that we’re going to see. That is, though Netflix and Disney + have content material in 4K, it doesn’t look the identical on each platforms, since picture compression, bitrate and a sequence of things come into play that we’re going to let you know about beneath in case you’re curious. otherwise you need to put them to the check.

Nowadays, with the advance of televisions and Internet connections, it is not uncommon for 4K has entered our homes. But it’s possible that once we sit down to observe a 4K content material from our streaming platform we will likely be upset, as a result of the pictures are very compressed, as a result of it doesn’t look pretty much as good as you anticipated … The 4K label is to not blame, however different components that, in every streaming platform, are completely different.

We discover, primarily, three “high quality” meters to know one platform or one other: whether or not or not the content material is 4K, bear in mind the bitrate and whether or not it has Dolby Vision or HDR10 (or HDR10 +)

What is 4K and what content material is in 4K

Surely you will have heard of 4K and we all know that it signifies that the movie, sequence or documentary seems higher. But what’s it? 4K decision refers back to the decision of 3840 × 2160 pixels and we will often see it as 4K or as UHD. Or like each collectively. This is as a result of the unique 4K decision is meant for cinema with a decision of 4096 x 2160 pixels, however it doesn’t adapt to the 16: 9 format of most televisions. In order to “fit” the 4K decision into the tv format, it’s dedicated to creating match the UHD or that 3840 x 2160 we instructed you about earlier than.

Offers us a very noticeable enchancment in pixels in comparison with earlier fashions like Full HD, for instance. It permits us to get an enormous variety of pixels that cowl your entire display even if you happen to purchase a really massive TV, protecting your entire display with out inflicting a lack of picture high quality. In addition, we at the moment discover many televisions of all costs and appropriate for any kind of viewers.


The very first thing we ask ourselves when in search of a 4K TV is: are we actually going to make use of it? Yes. Where is there 4k content material? Here we’ll examine the distinction of 4K in streaming platforms or what ought to we have a look at however it is best to know that the principle video OTTs supply us this decision: we will discover titles on Netflix, on Disney +, on Apple TV + or on Amazon Prime Video. Not on HBO, the place 4K has not but arrived and we nonetheless haven’t any information.

Of course, though they’re appropriate with 4K decision, it doesn’t imply that each one the content material will likely be seen on this high quality. There are films and sequence which might be out there with this decision however not all of them will permit us to get pleasure from 3840 × 2160 pixels. Generally we will see a label that tells us if we now have a appropriate system from which we’re going to play it.


To set up the distinction between one 4K and one other, one of many elementary factors that we should have a look at is the bitrate. As we now have mentioned, there may be lots of content material in 4K however not the whole lot goes to be the identical and we should attend to different components.

What is bitrate?

The bitrate of a video is the speed of information that’s reproduced over a time frame, often measured in seconds. That is, the upper the bitrate, the extra data will arrive each second and, due to this fact (though there could also be extra components), the upper the standard of the picture in query. Although we now have two movies in 4K decision, if considered one of them has twice the bitrate than the opposite, orViamente it can look higher. In reality, it’s in massive resolutions the place we must focus essentially the most on the bitrate, since there may be extra ‘hole’ to fill with data.

For instance, throughout lockdown in spring 2020, streaming platforms they lowered their bitrate because of the excessive client demand by its clients, to keep away from falls. As the demand is way increased than normal, the authorities requested a reducing of this bitrate to keep away from saturating the communications networks, even when that meant a loss in picture high quality. By the scenario, customers understood the measures. But as soon as the measures have been relaxed and the consumption of those platforms fell, virtually all of them recovered their normal bitrate and the typical client needed to know extra about this information that they beforehand didn’t know or didn’t think about necessary. That is why we’re going to overview what this information is in every of the most typical OTTs that attain our properties.

Bitrate of streaming platforms

According to measurements from the FlatpanelsHD web site, the OTT that comes out the very best within the comparability is Apple TV +. The tv of the Cupertino firm, at a decision of 3840 × 2160 and at 24fps, works with a bitrate of between 13 and 29 Mb per second, reaching peaks of 41 Mbps. It is the streaming platform that ‘broadcasts’ with the very best bitrate and fairly removed from its direct competitors.

The second OTT with the next bitrate in line with these measurements could be Disney +, which might transfer between 14 and 23 Mbps at 3840 × 2160 decision and at 24fps. Netflix wouldn’t be far both, though within the case of this streaming platform the info will not be up to date since its system has not too long ago modified and we’ll clarify it within the subsequent paragraphs.

As HBO doesn’t have 4K content material for the time being, of essentially the most widespread OTT we must discuss Amazon Prime Video, which as measured by FlatpanelsHD it could keep at 12-15 Mbps when it comes to video bitrate, navigating in that decrease step than Apple TV +, which takes the cake.

And we’re lacking Netflix, which, as we are saying, has not too long ago modified its system. Despite the truth that after the harshest confinement it had resumed its normal bitrate, the corporate has determined after the summer season to make a change. He promised to halve the bitrate sustaining high quality, however this has been proven to not have been the case. Its intention is to optimize the bitrate to avoid wasting bandwidth, however many customers have complained that this variation is admittedly inflicting the lack of picture high quality.

Dolby Vision and HDR

Bitrate is likely one of the high quality meters however he isn’t the one one. Therefore, we even have to have a look at different features corresponding to decision or, inside 4K, whether or not the content material is on the market in HDR or in Dolby Vision. We have to remember that you would be able to watch HDR titles in your cell phone on Netflix, for instance, with out this assuming that they’re 4K. We may summarize that 4K improves the picture high quality and determination whereas HDR10 and Dolby Vision enhance the colour of the pictures. photographs and make them extra practical. Both collectively get a significantly better picture however they don’t seem to be binding and never the whole lot we’re going to see in 4K streaming is HDR.

What is HDR10 and Dolby Vision

These are two applied sciences that strive to make sure that the unique shade and distinction of the content material just isn’t misplaced because of the transmission and the constraints of the gadgets. And there are additionally variations between each applied sciences. It could also be that two films will be performed on two completely different platforms and each with 4K decision however one might give you HDR10 and the opposite Dolby Vision. What occur? That even when it’s the similar film on each platforms and you’re enjoying the content material in 4K on each, it can look completely different on one or the opposite.

Let’s go in components … Both HDR10 and Dolby Vision are applied sciences that supply us the next high quality or realism within the photographs. The content material in HDR10 reaches a most of 1,000 nits of brightness and has a depth of 1,070 million colours. HDR10 is an open customary and anybody who needs to can create content material on it, simply as tv producers can use it with out paying. Not Dolby Vision, as it’s a much less frequent customary by which corporations should pay royalties. That is why solely a few of them work with this customary. Dolby Vision helps content material as much as 10,000 nits, though at current it’s only mastered as much as 4,000 nits. In addition, its shade depth permits it to achieve 68,700 million colours.


HDR10 and Dolby Vision are current on streaming platforms. On Netflix you possibly can see each though on Amazon Prime Video, on Disney + or on Apple TV + you will note one or the opposite. This will imply that the standard of the content material in 4K will likely be higher than in case you are watching the identical title with out this expertise, with larger realism in colours.

Dolby Vision and HDR on streaming platforms

Once we all know what to search for, past the title showing as 4K, we must know what which streaming platform provides. Dolby Vision expertise is current on Apple TV + and Disney +. Netflix is ​​a “particular” case as a result of we will discover content material in Dolby Vision but additionally in HDR10. For its half, Amazon Prime Video already has some content material that may be considered in HDR10 +.

What is best?

If you will have a really high-performance tv and also you need to profit from it, it is best to test that the OTT that you simply need to rent or have contracted has content material to make the most of it. With the knowledge that you would be able to learn within the earlier paragraphs, though with out neglecting the significance of the catalog of 1 or the opposite, you possibly can determine which one you need to guess on or which one is price it in case you are thinking about 4K content material. Although it can rely upon many components that 4K on one platform or one other is best, it shouldn’t be primarily the explanation why we may guess on them. For instance, if you wish to see just one film And to do it with this high quality it’s sufficient that you simply lease it on a platform such because the App Store or Google Play Store, for instance.
