MKV2PS3 is an application that can convert video files in the MKV container format to MP4 video files that are playable e.g. on the Sony PlayStation 3. MKV2PS3 can convert most common MKV files very quickly and has a queue for converting hundreds of files at once. MKV2PS3 can convert files so fast because it doesn't produce strictly standard conformant MP4 files, they play fine on the PS3 and elsewhere (see the F.A.Q.), but not everywhere (e.g. not iPhone compatible). Because MKV2PS3 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 the PS3 does not display them at this time.
