How to edit Vado HD videos with Cinelerra

Normally I edit my videos with PiTiVi. That’s easy, but has a disadvantage: HD-videos are getting rendered smaller and black bars are added (at least with my videos).

Now, I found an alternative: Cinelerra. Unfortunately, Cinelerra doesn’t recognize the sound of my Vado HD camera correctly. After some research I found a solution:

The following command-line extracts the sound from the video into a wav-file:

mplayer -vo null -vc dummy -ao pcm:waveheader:file=extract.wav video.avi

BTW: It’s fairly easy to convert videos with Handbrake. It even has multi-core-support! You can hear the sound in the resulting video, but Cinelerra still doesn’t recognize the audio.
