Handbrake

At the moment my favourite video editing tool, although not the easiest to get in your fingers. It allows detailed finetuning, and once well understood, delivers exactly what you want. It also supports hardware aceleration, which pushes my GPU to maximum encoding support.

Another personal favourite, especially interesting for lossless trimming / stitching / deleting / appending parts of a video file (use the ffwd/fbackward buttons to jump to keyframes that allow cutting).

(I suggest playing around with multiples of 50ms).
