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.
