No nitrate limit required, though we offer recommended bit rates below for reference Chroma subsampling: 4:2:0 When uploading other aspect ratios such as vertical or square, the player automatically adapts itself to the size of the video.
In addition, YouTube may take the following actions to interpret the color space values: Otherwise, YouTube converts the unsupported color spaces to BT.709 by mapping pixel values.
Note : YouTube converts the color primaries that require high bit depth (which does not use a supported HDR transfer function) to avoid banding, such as BT.2020, to BT.709 (8-bit). Warning : YouTube does not recommend the RGB color matrix on uploads.
In this case, YouTube initially sets the color matrix to unspecified before the standardization. Providing the best experience for your viewers is a worthy goal that all YouTubers should strive for, and one that can take many forms.
Fortunately, YouTube makes things easier by processing your video to ensure that the content being delivered to your viewers is up to scratch. Any time YouTube has to make changes, be it to the volume levels, the nitrate, the resolution, or any aspect of your video, there is a chance the results will not be to your liking.
Nitrate is the name given to the measurement of data encoded in a unit of time which, for video, is typically Mbps, or megabits per second. However, that higher nitrate comes with additional bandwidth requirements, which can mean a lousy viewing experience for people whose Internet connection (or computer hardware, for that matter) isn’t up to the task.
Another significant factor is the codec used since that will alter the amount of data an individual frame requires. And if this sounds like a foreign language, don’t worry, we’ll go over codecs in a little more detail shortly.
Now, whether this is a bad thing is subjective; if you are happy with the quality of the video at a particular nitrate, it doesn’t matter if it is low by any other standard. In fact, the lower you can get your nitrate without bringing the quality down too far, the better since it means a smoother experience for your viewers.
Higher nitrates will result in more bandwidth requirements for your user, which, may be necessary for certain video qualities. For example, streaming 4K at 60fps in anything approaching a decent quality is going to result in a lot of bandwidth; there’s no getting around that fact.
In cases where the bandwidth requirements are higher than your viewer’s connection can handle, they will get choppy, stuttering, buffering playback. In this case, the increase in demand on your viewer’s Internet connection is not worth it for the minimal improvement it grants them.
As we mentioned above, anytime you force YouTube to make changes to your video, you run the risk of them doing so in a way that you are not happy with. It is better to aim for YouTube’s preferred properties wherever possible, which in the case of nitrate, can be found in the table above.
That being said, YouTube put a lot of effort into making their platform work as smoothly as possible. The fact that the processing stage could alter your video in a way you are not happy with doesn’t mean it will.
For example, you could upload a 4K video with the encoding settings so perfectly aligned with YouTube that it needs no processing whatsoever… to display in 4K. In truth, the benefits of making your video match YouTube’s desired encoding settings apply more to other aspects, such as audio levels.

We could probably fill an entire post on each one, but it’s worth touching on them here since they are important terms to get familiar with when dealing with video encoding.
Typically, a container will include metadata that can tell a player information about the file, such as the title. With compression, that stretch of blank, silent screen can be significantly reduced in size since there is no need to store hundreds of frames of identical data.
For example, some focus on preserving as much detail as possible, which gives the best results visually, but doesn’t necessarily achieve a great reduction in data size. Other codecs might focus on getting the size down but, in the process, lose a noticeable amount of fine detail.
As with many things in life, choosing the right code is about finding a good balance between those two aspects. The resolution is fairly straight forward, and even those with little knowledge in this area are usually familiar with the concept.
The resolution of a video is the number of pixels being shown on screen, displayed as width and height. For comparison, a square video, where the width and height of the resolution are the same, would have an aspect ratio of 1:1.
By keeping your nitrates around the numbers suggested by YouTube, you shouldn’t have any issues with the quality of your video. When using YouTube to live stream or upload videos, the key to making them professional isn’t just the equipment you use.
If you use a YouTubebitrate that isn’t optimized for your Internet connection, you can increase buffering or lower the resolution of your stream. Streamergency n. The stressful situation when one's video call breaks down or cuts out unexpectedly.

Nitrate directly affects both the quality and file size of the video you are streaming. But, if the YouTubebitrate is too low, the file quality will poor and your stream will look unprofessional.
Here are some recommended nitrates for live-streaming and file uploads on YouTube : For example, in order to live stream a full HD 1080p @ 30 fps video on YouTube, you should have a nitrate of up to 6 Mbps.
If you’re uploading a full HD 1080p @ 60 fps video file on YouTube, you should set it with a nitrate of 15 Mbps. Everything including uploads, downloads, web browsing, gaming and streaming video can be improved by Speedily.
Speedily can bond any combination of 2 or more Internet connections and will intelligently distribute your online traffic between them for optimal performance. One issue many YouTube streamers run into is that they have a poor Internet connection.
This can prevent you from having a steady live stream, even if you are using the most optimal YouTubebitrate to avoid buffering. Speedily has smart technology: it only uses the minimum amount of data needed to keep your live stream up and running at your desired nitrate.
If I export my video from iMovie using the default 720p HD (High-Definition) settings, it takes my approximately 10 minute vlog and creates a file around 750 MB. Encoding my videos to H.264/AAC is already a pretty high compression and is also arguably the current industry standard (unless you ask Google, apparently), but fortunately there’s some flexibility within that compression to get an even smaller file size by adjusting the nitrate.
For my unscientific tests, I downloaded the MP4 of many 720p HD videos from YouTube across many users and channels. I also downloaded their FLY counterparts, which were actually 854×480 high quality videos, not true 720p HD.
Since it’s usually a good idea to encode with some overhead and give YouTube a higher quality video than it will produce. I’m using a Flip and a Canon HF100, fairly low-end cameras, so their image reproduction isn’t high enough quality enough to show much of a difference.
If I end up upgrading to a Canon 60D or 7D, the extra time dual-pass encoding takes will be worth it. With this I am able to encode files to approximately half the size I was previously getting from iMovie’s defaults.
It seems that the files still result with the same quality on YouTube as my 10 Mbps videos did and now my uploads also only take half the time. Tim Schmo yer blogs at Life In Student Ministry where he often shares what he's learning about online video as a communication and engagement tool.
Before we get started, please understand that Twitch and YouTube will deal with the data you send them differently, so we will split this guide into two sections. If you use a re-streaming service to stream to two platforms at once, it’s best that you use the suggestions provided in the Twitch section.
Alternatively, some services will allow you to choose separate settings for different platforms. Remember that all of these settings we will talk about will be within your streaming software, not on Twitch or YouTube.
Twitch will always reserve its bandwidth for its partners, so unless you stream during non-peak hours, your viewers won’t get access to quality options. If you stream at a certain nitrate, your viewers need to have the download speed to be able to match your upload.
If your upload speed is lower than this, you should try to find an alternative internet solution. Your viewers can then choose which quality option they want, and they won’t have any issues with buffering.
It’s highly recommended choosing the higher range in this list for the most optimal experience for your viewers. Ollie stumbled upon writing online whilst participating in a mobile network forum back in 2011.
