Hello,
I have some DIVX AVIs with AC3 audio (0x2000). I don't like AC3 for some hardware reasons :) My plan is: retrieve audio as separate file, use Azid or some other transcoder to get MP3 file and finally alloy MP3 with AVI video stream... (of course, VDub requires WAV, but it's possible to encode to MP3 in WAV format). Therefore, I launch VDub, open AVI, and select "Save To WAV". OK, it goes... I get some 200 MB WAV, BUT -
* Winamp fails to play it complaining some decoder error
* CoolEdit reports "Unknown Headerless RAW data" and, after import, I hear only random hiss (noise).
No good for me... Maybe wrong AC3 decoder scrambles resulting WAV? I have InterVideo retail, AVI is played in MediaPlayer correctly. Moreover, if I try to select Audio->Compression, the codeces listed doesn't give me bitrate choices, only empty list on the right side of the dialog!
So, can someone advise me how to extract AC3 audio track from an AVI in any USABLE format (AC3, MP3, WAV - doesn't matter, I'll transcode it) because VDub fails with WAV...
Thanks in advance. |

Vdub cant handle AC3. Use nandub from www.doom9.org ...

Hello
Winamp and cooledit complains because "save to WAV" does not actually decompress to WAV, but copy audio data. What you should do is :
Rename your extracted WAV file to .ac3 (because that's what it is)
Convert it to MP3 using something like BeSweet
Mux it back with video using Nandub |
