I've been making xsvcds for awhile now and I sometimes run into a problem with tmpeg 2-Pass vbr output size. I'll go through the wizard and lets say the bitrate is 1000-2100-3100 and it will say the output file will be about 800MB and after it's all down it turns out to be like 600MB so I'll go to reencode it agian and turn up the bitrate, let's say 1000-2150-3100 and after encoding it will turn out to be the exact size it predicted, like 820MB just by turning up the abr to 2150. Does anyone else experience this? I would keep the video at 600 but I don't like the results, I want all the room I can get.
