How to Set Perfect YouTube Video Dimensions

Every day new users sign up to share their masterpieces with the world on YouTube. If you also want to share your videos with the public, keep in mind that YouTube has a number of requirements for videos and their covers. Let's break down what video formats YouTube supports and how to properly format your videos.

in articles and forums but encounter an issue while uploading your clip.

The service will not accept it. Besides, a file in a certain format may be supported by the video hosting service, but the video codec used for encoding may not. In this case, an will be a useful solution. But to avoid double work, convert or save your work in the following formats:

1. 3GP;
2. AVI;
3. CineForm;
4. DNxHR;
5. FLV;
6. HEVC (compressed with H.265 codec);
7. MOV;
8. MP4;
9. MPEG4;
10. MPEG-PS;
11. ProRes;
12. WebM;
13. WMV.

The platform does not support blank audio files, even in such common formats as WAV and MP3. If you want to share your own song or track that doesn't infringe on its owner's rights, convert the audio to MP4 or another YouTube format and add a cover art or a series of thematic pictures. The following file types are acceptable as an audio track:

1. AAC (in MOV container);
2. FLAC;
3. MP3 (also in WAV container);
4. PCM (in WAV container).

A common question today is in which format to upload videos to YouTube. Today MPEG-2 and MPEG-4 are the best video formats for YouTube. Each of them has its own limitations:

• MPEG-4: audio playback speed of at least 128 kbps, H.264 video codec, and AAC audio codec.
• MPEG-2: audio playback speed from 128 kbps, Dolby AC-3/ MPEG Layer 2 audio codec.

. The higher the resolution, the better the playback and encoding flexibility. YouTube players have a 16:9 aspect ratio. Content in other formats will also be displayed without distortion as the system adds vertical (letterbox format) and
horizontal (envelope format) black bars around the edges. Use the following YouTube video dimensions to ensure that the video fills the player window completely:

1. 2160p: 3840 x 2160;
2. 1440p: 2560 x 1440;
3. 1080p: 1920 x 1080;
4. 720p: 1280 x 720;
5. 480p: 854 x 480;
6. 360p: 640 x 360;
7. 240p: 426 x 240.

YouTube automatically adds black bars so that videos are displayed correctly to satisfy YouTube dimensions without cropping or stretching, regardless of video frame size and player screen.For example, the system will add vertical stripes (letterbox format) to a 4:3 video to bring the image to a 16:9 aspect ratio. The same happens when the player is resized (e.g., when embedding on another site). Therefore, 16:9 frames are added at the top and bottom to match the 4:3 aspect ratio. Similarly, horizontal bars are automatically added to anamorphic videos ("envelope") in 16:9 or 4:3 players. However, this is only possible if the original aspect ratio is maintained. If you want to change the position of the added video in the player window, use format tags. If you have used horizontal bars in your video before uploading (e.g., to get a 4:3 frame from the original 16:9), the widescreen player will add vertical bars to them to achieve YouTube frame size. As a result, the image will be surrounded by a black frame, which gives an unfavorable impression of screen size.

Which bitrate should I upload the video to YouTube?

Bitrate is the number of bits that are used to transfer digital information per second. It has nothing to do with picture resolution and strongly depends on the codec used and container content. It is not necessary to make a special emphasis on the bitrate. It is better to optimize the video for frame rate and then compress the video for YouTube. Such an indicator as bitrate directly depends on a codec, so there is no minimum threshold. Standard bitrate for videos, which are designed for rental and sale — from 50-80 Mbit per second.

Ethical requirements

We've sorted out what format videos need for YouTube. But apart from technical features, there are also ethical requirements. So, before adopting the format for your YouTube video, make sure the video does not contain the following:

• Elements of a sexual nature or nudity: Video hosting strictly prohibits posting videos with pornographic or sexual content. This requirement is dictated by the protection of minors' rights and the security policy of the service.
• Dangerous Content: Dangerous content is defined as videos that may encourage viewers to be aggressive or hurtful. If the service determines your uploaded content is dangerous, it will be removed or subjected to an age restriction.
• Discrimination: Any user of the host can express their own point of view, but this must not demean or discriminate against other users, individuals, or groups, or call for violence against them.
• Sensationalistic or shocking content: If a video contains such elements, it will be thoroughly reviewed before being uploaded. A video is only uploaded if it is a documentary or news story and there is explanatory context.
• Intimidation, threats, and harsh insults. Gross violations lead to deletion of the material.

Recommended encoding settings for YouTube

In the final stage of producing a YouTube video, you need to have an idea of how to process it.When using an MP4 container, avoid using montage sheets.When working with the AAC audio codec, set stereo or 5.1 + stereo, and sample rate 48 or 96 kHz. Frame rate is the default, 24 to 60 fps. Remove interlacing before loading an interlaced video. Re-sampling is not permitted.H.264: Variable bitrate, progressive scan, pair of consecutive B-frames.

Conclusion

To upload content to your channel successfully, you need to know what video and audio formats YouTube supports, understand video encoding, and choose the correct aspect ratio in the converter or editing application settings.

It's important that your video is in a compatible format with the host, preferably with an aspect ratio of 16 to 9 and a resolution of at least 1280 × 720 pixels, always with interlaced scanning to get the best video size for YouTube. You can try a few options on your own to see which YouTube video format achieves the best results by experimenting with
it.
