Hi,
I am capturing from my analog video camera. I have an ATI 7500 AIW and I capture using Ulead Studio. I usually capture to AVI and then produce XVCD(720X480). I followed the guide posted in the forum(capture avi, edit/convert to mpg2 using ulead, use TMPGEnc to produce the XVCD).

When I capture clips for about 1 min(30 of them), the XVCD quality is excellent. However, if I capture ONE 30 min clip(the file size is about 48 GB), the end product becomes greener and the quality is quite low.
I don't understand why the file size might be a factor???
