I've read a little about color space and matrix but I am unsure what to do at encoding time. For example I have a source that is reported by MediaInfo as YUV 4:2:0 with "Format settings, Matrix" as "Default". What even is default? Considering the source is NTSC DVD, should I treat it as BT.601? If I do not specify anything during encoding, the resulting video will hold not information pertaining to the color matrix, and the color will be displayed exactly like the source. If I enforce BT.709 then the colors are slightly altered, but I am not entirely sure which is the correct one. I am wondering considering that a software like Handbrake will default to BT.709.
I would suppose that SD sources should be BT.601 and HD sources should be BT.709 but then again, it's just a guess at this point.
