Recommended upload encoding settings

Below are recommended upload encoding settings for your videos on YouTube. 

Container: MP4
  • No Edit Lists (or the video might not get processed correctly)
  • moov atom at the front of the file (Fast Start)
Audio codec: AAC-LC
  • Channels: Stereo or Stereo + 5.1
  • Sample rate 96khz or 48khz
Video codec: H.264
  • Progressive scan (no interlacing)
  • High Profile
  • 2 consecutive B frames
  • Closed GOP. GOP of half the frame rate.
  • Variable bitrate. No bitrate limit required, though we offer recommended bit rates below for reference
  • Chroma subsampling: 4:2:0
Frame rate

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.

Resolution and aspect ratio

The standard aspect ratio for YouTube on a computer is 16:9. When uploading other aspect ratios (vertical, square, etc.), the player automatically adapts itself to the size of the video, giving the best viewing experience based on the aspect ratio and device.

Color Space

Recommended color space for SDR uploads

YouTube recommends BT.709 as the standard color space for SDR uploads:
Color Space Color Transfer Characteristics (TRC) Color Primaries Color Matrix Coefficients
BT.709 BT.709 (H.273 value: 1) BT.709 (H.273 value 1) BT.709 (H.273 value 1)

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:

When YouTube Action
The upload color space has unspecified TRC. Assumes BT.709 TRC.
The upload color space has unknown or unspecified color matrix and primaries. Assumes BT.709 color matrix and primaries.
The upload color space mixes BT.601 and BT.709 color primaries and matrix with specified values. Uses the color matrix to override the color primaries and make them consistent.
The upload color spaces mixes BT.601 and BT.709 color primaries and matrix, and either primaries or matrix is unspecified. Uses the specified value of color primaries/matrix to set and override the unspecified one.

After the upload color space standardization, YouTube checks if the color space matches BT.709 or BT.601, in which case the color space passes through. 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). YouTube converts full color range to limited color range.
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. It will then infer the color matrix using the color primaries during standardization. Note that sRGB TRC will convert to BT.709 TRC. YouTube re-tags the color primaries/matrix/TRC to BT.709 if it is not supported by Ffmpeg colorspace conversion filter.
