how can i rip AC3 from Avi file?

[wizzy]

not with VirtyalDub....the output from that is bad....for me...
any other application do that?

What do you mean exactly? If you save the audio direct stream copy from Virtualdub you have the AC3 saved exactly as it is - albeit with the wav extension, which you simply change to AC3.

first is XVID so i dont have msg when i load the file than when i save avi like you said...i have bad result in the end...and its only with XVID , DIVX is ok

Then you can probably use Graphedit. I don't know offhand what filters you will require, but if you load your XviD into Graphedit and describe the filter graph (ie the various boxes) you see I am sure we can make progress.

However, I make the presumption you can actually hear the AC3 audio when you play back the XviD. If not, you will need to install the XviD codec first, or perhaps only ffdshow to allow XviD playback on your system.

I'm saying use VirtualDub, select audio - direct stream

Download Besweet and Besweet GUI from www.doom9.org

Use AC3 - mp2 if your planing to make a vcd/svcd.

If your just wish to rip out it as AC3 use VirtualDub then get AC3 fix to remove the .wav header that virtualdub inserts to your AC3 stream.

I suspect he may be having difficulty actually loading the XviD into Virtualdub.
