| Hi, I am capturing AVI files off my cable TV (using Virtualdub of course). Divx & AC3 are being used. I wish to remove two annoying noise lines at the top which show up on some channels by serving Vdub the following simple avs script: AVISource("D:\Capture\test.avi") crop(0, 2, 0, 0) AddBorders(0, 1, 0, 1) Problem is the audio in the resulting AVI file is now PCM instead of AC3 I specify direct stream copy for audio, Full processing for video, compression using Divx and than Save AVI. Passing the same file directly through Vdub (no Avisynth) keeps the AC3 audio. What am I doing wrong here? I'd like to keep the audio as AC3. Thanks to all in advance. Never mind. I just figured it out. (Audio should also be full processing mode). |

Maybe just demux audio before video recompression and add again after? (Of course if You not cut video or change FPS...) |
