Converting MPEG to WAV

Hi Everyone,
I’m brand new here and just starting to dip my toe into the wonderful world of video editing. I just bought Cyberlink PowerDirector. For my first project, I’m trying to find a away to take an mpeg movie and convert it to a wav file...this is so I can use the audio from the movie as background music while I have different video (with their own audio track) playing on top of it.

Can this be done? I’ve tried downloading some of the free trial versions out there, but they seem to always fail when I try adding my video. Plus. they can only do 1 minute.

Any help would be appreciated.

If you don’t need a wav file, but can work with MPEG audio, here’s what you can do. Get TMPGEnc from http://www.tmpgenc.net (click on downloads at the top after you select your language). Open TMPGEnc, skip the wizard. Click on File, MPEG Tools. Choose the Simple De-multiplex tool. Browse for your MPEG file and then click run. If you’re using MPEG-1, the audio will be .mp2 and the video will be .m1v. I think MPEG-2 video will be .m2v.

you can try use E.M. HD Video Converter
