- Avidemux: gives you the best of both worlds with the ability to control bitrates, codecs, filters and so on, but also has a handy 'Auto > ' feature that automates the creation of video for things like Youtube, iPod, DVD etc.
- Arista Transcoder: The best, easiest to use transcoder I've seen. Presets take the hard work out of conversion, and there are a lot of presets.
- PiTiVi: this is a video editor that also supports exporting to a range of different file formats. Easy to use trim feature, transitions and effects and pretty simple export at the end of the process too.
While we're at it, can I also say how impressed I am with Google's open source video codec called webm? Try it for yourself with Arista: convert a large DVD quality file to webm and see what a difference it makes. I've had file size savings of up to 90%.
