Einar, I'm not suggesting changing the editing engine. Ffmpeg is a good tool for transcoding and rendering audio and video (especially for DVD or Bluray). Transcode and Mjpegtools have not kept up with technology. All the editing functionality in the world is useless if you can't create a finished product. The current ffmpeg interface is so far out of date that it doesn't allow 1/10th of ffmeg's current functionality forcing extra steps in rendering, often times with loss of audio or video quality.
Some functions that would be nice to have are: Pre-defined surround sound audio configs (the angle configuration make no sense for the lfe channel (an lfe plugin would also be nice)) and simultaneous audio and video rendering.
