Whats the best app recomended for screen recording? Im interested in recording 5 seconds of a .MKV file. I could convert and edit in iMovie, but I believe the conversions plus the editing/publishing will make me lose quality, not to mention it would take hours to trasnport the .mkv file to imovie. I thinks its best if I simply capture the part I need while playing in VLC. How good is the Quicktime quality? Should I get a better app? I want to get best video quality.
