Encoded audio pitch too low converting from 30fps to 25fps

[Lint Ninja]

Converting from Divx4 with mp3 audio @48khz. Resulting svcd encodes fine, audio is in sync but voices have gone down 1 or 2 octaves.
So i have a stupid question - is there another step i can introduce to resample the extracted wav to keep the pitch (like pause operation, use something like cooledit to resample, then continue with encoding)? Or is there a setting within avi2svcd i've missed?

Either that, or i stop trying to be so damn spoiled and actually do some manual steps rather than using this cool app :)

Hi Lint Ninja,

have you already tried to set audio to 48kHz in "Audio" tab? - I think the pitch shifting is caused by the upsampling of the audio to the default of "128" kHz - but don't know for sure (DSPguru might help!?). ;)

So try with 48kHz Audio setting as your source is already 48kHz and it should not gain any improvement with 128kHz.

Greetings,

Tried changing to 48khz, and also changing the bitrate - none have any effect - still the same low pitched voices.
Only audio setting i haven't found is the toolame mode - just going to quickly try it

Tried all settings for audio now - no joy :(
Is there anything else i should be trying?

i guess u tried downsamling to 44.1
im not familiar with divx with dvd2svcd but i have had the problem once with a dvd and downsampling fixed it for me.
