When I'm ripping one of my DVD, I found that the original colorspace is YUY2(base on the Information from PowerDVD), but when I use DVD2AVI to put the Vob file into the encoder, it was reconized as YV12(from Avisynth 2.5 info()). Is there anyway to keep the original YUY2 colorspace without put a covertYUY2() filter in Avisynth Script? because I want to use some filter that only works on YUY2 and I don't want to change the colorspace.
Almost all DVDs store the video as YV12. PowerDVD probably just decodes it to YUY2 and reports that back to you.
If you check the AviSynth FAQ you'll find the regular mpeg2dec.dll (which outputs YUY2) in a version that works for AviSynth2.5x. |
