Sound doesn't convert using AutoGK

[Looler]

I've got a .mpg video that I want to convert to avi (XviD) using AutoGK. Everything is working fine and the output size is good, the only problem is that it doesn't convert the sound to mp3 as I asked in the settings. It only keeps the original audio (AC3). Is it because AC3 isn't supported with this program?

Thanks for your help!

AC3 is supported. It'll keep the original audio under certain circumstances. Did you go into the Advanced Settings and force it to convert to MP3 audio? Post a log for one that kept the original audio when you didn't want it to.

I selected MP3 on the Advanced settings (Output audio type).

So, either it made a mistake or you made a mistake. What's the AC3 audio bitrate? I suppose there's a chance it doesn't support AC3 bitrates different from the DVD ones. Is it 640, by chance?

You could easily convert it yourself to MP3 and mux it in, replacing the AC3 audio. It would save you reencoding it.

The bitrate is actually 384. So I'll have to demux it, convert to MP3, mux it and finally use AutoGK?

[manono]

No, you demux it, convert it, and then remux it into your AVI, disabling the AC3 in the process. However, if you follow that process I just outlined you won't reach 350MB and the video quality won't be quite as high as it would be if the audio had been converted to MP3 originally.

Unless there's something wrong with that AC3 audio in that MPG file of yours, I'd suggest running the entire thing through AutoGK again. Make sure to set the MP3 up in the Advanced Settings. Then, keep an eye open for that, "Audio 1 settings: Original. It'll appear almost immediately. If you see it, abort and maybe do the encoding manually if you're capable of that.

[Looler]

I just finished to convert a remuxed file with the MP3 audio, and it worked.

Thanks for your tip about the early abort (I won't have to waste 3-4 hours anymore) and all your help.
