@Adamcarter PM'ed to you...

Also in addition to color edges degradation. I notice that there is a some brightness levels shift when use Color -> ColorMatrix transform.
Seems brightness levels shift visible only in VS viewer preview. When rendered to x264 and in player levels are back to normal.
But chroma edges artifacts are still there.
UPDATE. seems chroma edges artifacts where caused by MPEG1 source. Seems Hybrid reads MPEG1 in some strange way. When i convert source file to 10bit ProRes422HQ and import again in hybrid, chroma edges have no artifacts when i apply 601 to 709 color matrix. But anyway other problems with color matrix still exists. I am not soo deeply technical in theory to explain the nature of this transformation. SeemsĀ part of this problem was discussed here:
