MKV2M4V can convert MKV files to M4V(MP4) files. It is very fast because it converts only the audio tracks, while only copying the video track. For that reason, it can convert while preserving the full video quality. It can also decode FLAC audio. And if you have a SRT file, it is available to insert as a closed caption.
v1.3 [Oct 6, 2014]
• Fixed the issue that os type options are not applied to the closed caption.
• Fixed other minor bugs.
• Improved parsing for ASS/SSA format.
