How to fix converted QuickTime movies that have no sound

I've been making some short videos of my son with my new digital camera, a Sony CyberShot DSC-H50, with the goal of syncing them to my iPod Touch so that I have them around to show to family, friends and colleagues.

However, when I use QuickTime to convert the video to the iPhone/iPod Touch format, I get stuck with a video with no sound. And why is that? It's because my digital camera (and as most digital cameras) records the video and audio on the same stream within the movie file. And QuickTime is only able to convert movies that have separate video and audio streams.


In search for a solution to this problem, I found this neat program that takes care of that conversion real easily: MPEG Streamclip.

So if you're having similar problems, make sure you give this program a try.
