Below are recommended upload encoding settings for your videos on YouTube. No Edit Lists (or the video might not get processed correctly) moov atom at the front of the file (Fast Start) Channels: Stereo or Stereo + 5.1 or Stereo + Eclipsa Audio Sample rate: 48kHz Progressive scan (no interlacing) 2 consecutive B frames Closed GOP. GOP of half the frame rate. Variable bitrate. No bitrate limit is required, though we offer recommended bit rates below for reference Chroma subsampling: 4:2:0 Content should be encoded and uploaded in the same frame rate it was recorded. Common frame rates include: 24, 25, 30, 48, 50, 60 frames per second (other frame rates are also acceptable). Interlaced content should be deinterlaced before uploading. For example, 1080i60 content should be deinterlaced to 1080p30. 60 interlaced fields per second should be deinterlaced to 30 progressive frames per second. The bitrates below are recommendations for uploads. Audio playback bitrate is not related to video resolution.

Recommended video bitrates for SDR uploads To view new 4K uploads in 4K, use a browser or device that supports VP9. Recommended video bitrates for HDR uploads Recommended audio bitrates for uploads The standard aspect ratio for YouTube on a computer is 16:9. When uploading other aspect ratios such as vertical or square, the player automatically adapts itself to the size of the video. This setting gives the best viewing experience based on the aspect ratio and device. Learn how to use video resolution and aspect ratios correctly. Recommended color space for SDR uploads YouTube standardizes functionally similar color matrices and primaries before processing the video. For example, BT.601 and BT.709 TRC are identical, and YouTube unifies them to BT.709. Or, BT.601 NTSC and PAL have functionally similar color matrices and YouTube unifies them to BT.601 NTSC. In addition, YouTube may take the following actions to interpret the color space values: After the Upload Color Space Standardization, YouTube will check if BT.709 or BT.601 matches and passes through the color space. Otherwise, YouTube converts the unsupported color spaces to BT.709 by mapping pixel values. Recommended color space for HDR uploads Refer to the Upload HDR videos article. Was this helpful?
