YouTube Video Formats

Which configuration to choose for the best result

YouTube Video size

Google Corporation sets a number of requirements and offers many recommendations on video format, codec, bit rate, and resolution to upload to YouTube servers. Clips should be added in the highest resolution available, ensuring high image quality when viewed on large screens, flexibility when converting or rendering after editing.

Videos intended for rental should have a frame size of at least 1080p (Full HD) and an aspect ratio of 16 to 9, the parameters of most modern monitors. For commercial videos where you plan to insert ads, there are no frame size restrictions. However, you should not upload files with frame sizes below 720p at 16: 9 and 480p at 4: 3. With low quality, users with large monitors will find it uncomfortable to watch video footage, they may miss its content.

It is worth knowing that after downloading the video, YouTube always re-converts the material to optimize the playback quality.

In what format can you upload videos to YouTube?
In search of information on what video format is needed to upload to YouTube, you can re-read dozens of pages of information in articles and forums, and when you try to upload a finished file, you run into a problem. The service will not read it. At the same time, a file of a certain format may be compatible with a video hosting service, but the video codec used to encode it is not. To avoid duplicate work, convert or save your work in the following formats:

3GP;
AVI;
CineForm;
DNxHR;
FLV;
HEVC (compressed with H.265 codec);
MOV;
MP4;
MPEG4;
MPEGPS;
ProRes;
WebM;
WMV.

The platform does not support pure audio files, even in such common formats as WAV and MP3. If you want to share your own composition or track that does not violate the rights of its owner, convert the audio to MP4 or other format by adding a video sequence in the form of a cover or a series of thematic images. The following types of files can be used as an audio track:

AAC (in a MOV container);
FLAC;
MP3 (included in a WAV container);
PCM (to WAV).

The resource administration does not give recommendations on the most suitable format, however, it is advisable to give preference to MP4 due to a number of characteristics of the container. For example, most digital devices write in MP4, many media players are sharp for it, the format has a higher compression ratio than AVI.

Video size (resolution and aspect ratio)
The size of a video to upload to YouTube depends on the way it is viewed: in an Internet browser, an application for the Android or iOS mobile platform, a third-party player, and the format: classic horizontal or vertical, shot on a mobile device. The player for mobile platforms adapts to the dimensions of the video, regardless of its orientation, trying to fill the maximum area of ​​the screen with useful content. In this case, the frame is neither stretched nor compressed.

The YouTube video player window has a length-to-height ratio of 16 to 9. Deviating from the royalties is not recommended; this is a classic format, the most widespread in the world.

When playing videos with different settings, gray or white bars may appear in the corners or at the top and bottom of the screen, depending on the active theme. They will be black in the internet browser. Avoid the appearance of these stripes in the video during recording and eliminate them during editing. They make it more difficult to automatically resize the player window.

The optimal video size for YouTube in 16: 9 progressive scan is shown in the table. Meeting the requirements will prevent solid color streaks on the sides or below and above the image when viewed on most mobile devices, televisions and monitors.

It is advisable to take care of the video transmission format (1080p) and MPEG-2 or MPEG-4 for DVD players. The following features ensure that there are no playback issues in any way, regardless of device and platform.

Best format for Youtube videos

Youtube videos format

Let’s see what is the format that allows you to retain the highest quality when you upload your video to YouTube. In case you do not know, in fact, once YouTube has acquired the video on its servers, once the upload is finished, it proceeds to recode it and therefore it is important that we provide a file with the highest possible quality and with the specifications that you require.

YouTube video formats

CODEC

Let’s start with the CODEC. The choice is almost obvious and falls on the ubiquitous H264. Used both in the acquisition phase in many camcorders, and in the distribution phase, it is the best option even when we want to share movies on the Web. The reason is very simple: with the same file size, it provides the best quality. Then, in your editing or encoding program, select it. Of course it would be nice if it ended here. Actually, this algorithm can have variations within it, which I will not explain in detail because it is a very complicated and long speech.

What you need to know is that the H264 profile that YouTube asks us is HIGH, its entropy mode is CABAC and obviously it must be progressive and not interlaced, since we are going to upload a video that will be seen on PC, smartphone and tablets and not on old televisions. Regarding the bit rate, that is the amount of data per second, YouTube tells us that we can leave it automatically, even if as a reference it suggests selecting 8000Kbits / sec for movies in FullHD and 5000 for movies in HD.

We can increase these numbers, but keep in mind that as they grow, the size of the files increases, with more time to load and more space for storage.

CONTAINER

Regarding the extension, that is, the container, mp4 is the best option. Obviously, the frame rate, that is, the number of frames per second, must be the same as what you recorded and edited at.

PHOTOGRAMS TO THE SECOND

For example, if you choose 25 frames per second in these two stages, make sure it is the same when uploading.

AUDIO

Ok, this for the video part. And for the audio?

The choice here falls on the AAC-LC codec, which is obviously stereo and with a sample rate or sample rate of 48Khz.

I know it sounds complicated, but once you dictate these parameters into your encoding program and save them, you just have to select them when exporting and you can forget about them. You may be thinking: but my program already has the ‘export to Youtube’ function, can’t I use it? The quick answer is: you could do it, because in any case they generally have parameters that go more or less well with what YouTube asks us.

However, if you want maximum control and quality, create a preset with the parameters that I told you before, and that I will now quickly summarize:

H264 codec with HIGH profile, CABAC entropy mode and bit rate that can be automatic or 8000 Kbits / second for FullHD movies and 5000kbits / sec for HD movies
extension in mp4
number of frames per second that is the same as the one you recorded and edited as long as it is between 24 and 60 fps
Progressive and non-interlaced movies (for example, 1080p and not 1080i)
48 kHz audio, compressed in AAC-LC
