⚠ Using this command it is possible to add Rec.709 tags to a file that is actually Rec.601 (etc), so apply with caution!
These commands are relevant for H.264 and H.265 videos, encoded with libx264
and libx265
respectively.
Note: If you wish to embed colorspace metadata without changing to another colorspace, omit -vf colormatrix=src:dst
. However, since it is libx264
/libx265
that writes the metadata, it’s not possible to add these tags without reencoding the video stream.

For all possible values for -color_primaries
, -color_trc
, and -colorspace
, see the FFmpeg documentation on codec options.
1. Out of step with the regular pattern, -color_trc
doesn’t accept bt470bg
; it is instead here referred to directly as gamma.
