Avidemux

Fugly & buggy — but still the easiest, lightest and yet versatile video editor with GUI.

Absolute amazing! Just cut out a section out of an mp4 file without re-encoding (no loss of quality!) - excellent stuff!

Simple, quick and surprisingly versatile little video editor that runs quite well on my modest Windows PC.

I was looking for simple solution to cut the scene from a .avi movie without loosing quality. For this purpose - perfect.

Note that no program supports WMV because that is Microsoft proprietary. You can only use Windows Media Encoder with that.

Other than pointing that out, this program is great for editing the files that it is listed to support. If you can't read that list and don't understand, then perhaps you should move on to a different program. It is multi-platform as well. I use it on Windows 7 and Linux Mint without a problem.

The problems I have with Avidemux are:

1. it doesn't support WMV or VC1
2. it won't import my DVD files. [I have a DVD-R that I recorded so it's not locked or anything.]
3. there's no real timeline editor thaT I can see which means that overlays and voiceovers are out...?

I don't like Avidemux. There are some little annoyances, like very bad, not reconfigurable shortcuts if you're using an non-english keyboard-layout. The preview is not scalable. You have to input the output name if you're saving cutted parts, again and again. It's not very stable (in Windows only?). It's having big trouble with converting mpeg2-streams, but it don't display any hints it's not able to convert it. So you have to wait hours of encoding too see the audio is asynchron, the resolution wrong or other problems. That's all points VirtualDub is much more comfortable! But Avidemux supports a lot of codecs and containers, while VirtualDub is very limited. I hope AviDemux will gain quality in the future, then it would be a really great tool.
