How did you manage this? What tool did you use? Even erightsoft's Super, supposedly the most feature rich freeware video converter doesn't have an option to convert from yuv to rgb24, nor anything mentioning color space at all.
I actually converted the videos to some YUV444 format I think, which seemed to match the quicktime originals. The tool I used was ffmpeg
. However, the LAV video decoder (which the game automatically chose as its default decoder with the unofficial patch in place) allows you to select which output color spaces are allowed - so I set it to only allow RGB24. You should be able to do the same with with ffdshow if you prefer that. Most other spaces just show up as black, and RGB32 gets really choppy for some reason.
If you want my converted videos, by the way, just ask and I'll PM you a link (I'm not sure how GoG would feel about me uploading content from the game here, converted or not).
