I'm looking for two programs (or one that does both). Firstly i want to cut video without any quality loss. It has to be the same video as before but without cutted parts. I have tried avidemux but it lets you cut in specific parts which is very inaccurate. HandBrake gives you more freedom, but you can't choose milliseconds which is quite inaccurate too.
And i want to convert mkv video to mp4. The same as before, without any quality loss, it has to be the same video, but mp4.
It can be paid software as long as it does what it should.
