Color space used

Hello.

With the VirtualDub plugin, you can only feed RGB data.
From what i've understood, you convert internaly to YUV.
As there is no setting (unless i've missed it) to provide the colorspace information, how do you choose the correct colorspace matrix (BT.601, BT.709, BT.2020) to use to convert properly to YUV ?

My sources are alway YUV, i have to convert to RGB, but i hope, and it would be the best, that after when you convert back to YUV you use the same color space matrix.

Do you choose according image size ? Or do you always use the same ? In the last case, which one ? (At least that i use the same).

We always use the same custom one internally. It doesn't have to be a specific one or to match your color space. The internal one may also change from version to version. That should make no difference from an external point of view.
