I'm trying to figure out the best settings for converting or recoding a mkv file into a mov or mp4 or something after effects will allow me to import.
I've read up a bit about recoding the mkv, it works as a container right? And switching to something else will be the least corruptive way of getting the footage out. What's the best way of doing this and what format settings etc to choose?
I've tried using MKVExtractGUI-2 to do it but it doesn't seem to like me and keeps telling me there are no chapters in the file I'm trying to use.
Another thing is the file is quite big so I was also looking for the best way of extracting sections out, can you do that to pieces when you recode it or do I just do the whole thing?
Thanks very much for any pointers or help.

It depends on what compression is used for the audio & video. You could use mediainfo to find out (view=>text)
If it's compatible , you could stream copy into MP4 container using something like avidemux or ffmpeg
You can also cut a clip at the same time using avidemux or ffmpeg.
If it's not compatible, then you could re-encode to a lossless codec (it will likely be several times larger than the original), or an image sequence (e.g PNG sequence)
