or does frameserving to TMPEG cause some quality loss? I noticed that if I use avisynth to create a second avi file that has been filtered and THEN encode with TMPEG, the resulting mpeg is clearer than if I frameserve with either VDub or TMPEG to avoid the middle file. Anyone else notice this? I've tested it by creating small clips with both methods and the frameserved ones had more artifacts and noise. Hope someone can explain it.
