Audio Compression

All the pros who've been rating my amvs have been giving me flak about not compressing my audio. I looked at the guides and all they show is how to compress into a MP3, but most of my audio are already MP3s. I searched in the forums but found nothing. So can someone tell me how to compress audio please.

how are you exporting from your program?

when you go to compress you might need to compress the audio again, it doesnt stay as an mp3 when you export uncompressed

It seems that you use the same settings to export all of your amvs, except for the first one, which has a wma track.

PCM @ 1411.2 kbps
44.1 kHz, stereophonic sound

Change the project properties before exporting the final render. If you don't know, then you can tell us the program you are using and we can tell you how to.

For my last three I was using Sony Vegas 7, for my latest AMV I'm using Premiere Pro CS3. So I'd need to know how to do it for premiere, at least for now. I doubt I'll go back to Vegas. Premiere takes some getting used to but is smoother and has a lot more to work with.

Don't compress your audio on export from the editing program. Encode it separately and join the video and audio together in VDub (or MP4Box or MKVMerge, etc., depending on what format you're using), or encode the audio while compressing your video for distribution in VDub.

So you're saying just send out the video on it's own and add the audio. Honestly, not sure if I saw a guide on how to join them up in Vdub, could someone give me a quick once over on how to do it. I pick things up pretty quick so it shouldn't be that big of a problem. Or point me to a guide if I missed one.

Exporting from Adobe Premiere Pro

Compressing video with XviD

Compressing audio with MP3 (and muxing the video and audio together)

If you are lucky, the original MP3 may be used together with the video which avoids losing audio quality due to re-compression (MP3 > WAV > MP3). Depending on your circumstances, this might not be possible if you edited the audio or if your video depends on tight sync with the audio (since the audio may have changed during editing of the video in some way, possibly during export).

I was looking at that New Program Zarx264. Seems like it can combine the audio and Video pretty well. I'll most likely use that method. Thanks everyone For all the help.
