Mkvtoolnix - Set Color Space Conversion Flag to REC709

[0028606]

I was wondering if there is a way to set the Color Space Conversion flag
for HD content to REC709 when muxing .264 video in to .mkv container using mkvtoolnix

You're supposed to set Rec.709 when you encode your .264 file. You can use the --colormatrix command in x264 to do it.
