[12.1 MB] MKV2MP4 1.4.9 is an application for mac that can convert MKV to MP4 and supports multiple internal and external audio tracks. Supports subtitle format: SRT, ASS, SSA, ttxt, can change subtitle color
MKV2MP4 can convert most common MKV files very quickly, and has a queue for converting hundreds of files at once. MKV2MP4 can be configured to either produce files with perfect compatibility (at the expense of conversion speed) or to do conversion extremely quickly by producing files that are playable on most, but not all players (see F.A.Q.). Because MKV2MP4 doesn’t re-encode the video track, conversion is fast and the resulting video has the exact same high video-quality as the source file. Note that most subtitles are supported (see F.A.Q.) but some players do not display them.
