ffmpeg 만세

If you only want to convert mkv to mp4 then you will save quality and a lot of time by just changing the containers. Both of these are just wrappers over the same content so the cpu only needs to do a little work. Don't re encode as you will definitely lose quality. It's very straight forward using ffmpeg: ffmpeg -i LostInTranslation.mkv -vcodec copy -acodec copy LostInTranslation.mp4 Here, you are copying the video codec and audio codec so nothing is being encoded. Tip: To convert all the mkv files in current directory, run a simple loop in terminal: for i in *mkv; do ffmpeg -i $i -vcodec copy -acodec copy $i.mp4; done
