I'm only interested in the "editing part" of Kinovea (it's the cleanest I've seen for a while) and it would be nice if the outputs could be in the same format that the inputs, with no transcoding involved.



Currently this is not possible and not to be expected in the foreseeable future.

The main reason is that some of the main usages include saving with drawings painted on which need recoding. When muxing to AVI, not all codec would be available, also, depending on codec, not all framerate are possible, which would mean yet another case for saving with slow motion.

It was initially trying not to reencode if not needed, but it proved too much of a hassle to maintain.
It's a bit of a shame but it's currently the only maintainable solution for me…
