Audio Issue when encoding AVI File to MP4

[dany66]

Im trying to convert an AVI file to MP4 however the audio is always low pitched and sounds slightly crackly.

The camcorder I used is a Sony DCR-TRV130E and I have imported the footage from a mini dv tape via firewire to a 2009 macbook pro running windows 7 32bit.

The AVI file plays back perfectly with no issues at all but when converting it to an MP4 using handbrake the audio messes up and sounds low pitched and crackly.

I have a few mini DV tapes and almost all of them have the same problem when converting the AVI file to MP4.

All of the audio settings on handbrake are on default. I have tried changing them but previously but nothing has worked.


I'm not sure what to do here as I am a newbie to importing mini DV footage any help would be appreciated

Could you post a mediainfo report (text mode) from your avi here?
Maybe you can simply remux the avi to mp4, without recoding.

Pcm audio is incompatible with the mp4 container.
It must therefore be recoded. A lossless option for mp4 would be flac.
Other lossy options are ac3 or eac3.

Pcm audio is incompatible with the mp4 container.

Actually it is compatible. The problem is in the open-source software (read: ffmpeg), which is unable to deal with that.
