MP3 or WAV for SVCD audio/Problem Encoding Audio

[metranil]

Hi,

I have two separate but related questions:

1. Can anyone suggest whether or not a WAV or an MP3 would be better for a SVCD?

I am capturing to avi, then using TMPGEnc to convert to MPEG2. I open the audio portion in Cool Edit Pro in order to normalize, etc. I thought I used a WAV for my first test, but a subsequent trial had TMPGEnc giving an error saying WAV was an unsupported format.

If one uses a high quality MP3 instead of a WAV, can it save room on the disc for better quality video?

2. Like I said, my first capture trial produced an AVI. I opened the audio portion using Cool Edit, made some changes, then wanted to save my changes. It saves to the same name as the AVI, instead it has a new extension -- WAV. I had trouble getting TMPGEnc to accect the WAV file in the audio portion. Is there some way to save changes to the original avi audio so that is stays locked with the avi video, yet reflects the changes you made?

Thanks,

Brian

Neither, SVCDs most have mp2 audio. But I think what you're asking is what makes a better audio source for TMPGenc to encode? If so then wav. Everytime you compress your video/audio you lose 'some quaility' No need to capture, spilt to wav, encode to mp3, encode to wav, encode to mp2.

Instead just capture, extract wav file, normalize, encode wav file to mp2. TMPGenc can open wav files. If you couldn't open your wav file something went wrong somewhere (did you save the normalized wav as PCM audio).
