I have a folder full of MOV videos taken by my DMC-FX10. The problem is that the occupy too much space, and I am wondering if it is possible to compress them without losing quality?

All videos have a resolution of 640*480.

Example: 3 minutes video @ 30 fps takes 240 Mb of space with a data rate of 11446 kbps and a similar total bitrate.

I imagine ffmpeg could reduce the size of those videos:

ffmpeg -i -c:v libx264 -c:a copy -crf 20

Or just download Handbrake if you want something with a GUI. Handbrake will also allow you to queue re-encodes.

Beware that you will lose quality no matter what. The movies from the camera are already compressed with a lossy codec, so there's not much you can squeeze out there without losing quality. – slhck Dec 28 '12 at 17:07
