Not on Windows :-) I'm trying to first convert the two files into
something smaller, before editing/joigning them with eg. AviDemux or
some other NLE editor.

Is there a codec that would give a less compressed output than mpeg4?

ffmpeg -i myfile.mts -s 640x480 -codec:v mpeg4 -profile:v 3 -codec:a
copy myfile.mp4

Thank you.
