Otherwise, YouTube converts the unsupported color spaces to BT.709 by mapping pixel values. Uses the specified value of color primaries/matrix to set and override the unspecified one.Īfter the Upload Color Space Standardization, YouTube will check if BT.709 or BT.601 matches and passes through the color space. The upload color space mixes BT.601 and BT.709 color primaries and matrix, and either primaries or matrix is unspecified. Uses the color matrix to override the color primaries and make them consistent. The upload color space mixes BT.601 and BT.709 color primaries and matrix with specified values. Reduce video file size by adjusting video parameters like frame rate, bitrate, resolution, etc. The upload color space has unknown or unspecified color matrix and primaries.Īssumes BT.709 color matrix and primaries. Crop, merge, rotate, and split videos within the program.

The upload color space has unspecified TRC.

In addition, YouTube may take the following actions to interpret the color space values: When Or, BT.601 NTSC and PAL have functionally similar color matrices and YouTube unifies them to BT.601 NTSC. For example, BT.601 and BT.709 TRC are identical, and YouTube unifies them to BT.709.

YouTube standardizes functionally similar color matrices and primaries before processing the video.
