MKV2MP4 PS3 MP4
MKV2MP4 is an application that can convert video files in the MKV container format to more compatible MP4 video files. This will be a lot slower and incur some noticeable quality degradation, but at least the resulting file will be valid, compatible and playable.MKV2MP4 1.1.0 - Rapid, lossless MKV-to-MP4 conversion.
This means that HEVC MKVs converted with MKV2MP4 1.4 or newer should open just fine in QuickTime Player on High Sierra or iOS 11 or AppleTV devices with tvOS 11. Therefore MKV2MP4 starting with version 1.4 will fix-up the tag of converted HEVC MP4s from 'hev1' to the supported tag 'hvc1'. However, by default Apple's players refuse to open HEVC MP4s if these contain the common default 'tag' called 'hev1'. Apple has introduced support for HEVC in macOS 10.13, iOS 11 & tvOS 11. So the resulting MP4 will only play on video players that support H265/HEVC. If you are converting an MKV that has a H265/HEVC video track, the same thing happens, this video-track is embedded unmodified into the resulting MP4 file. Therefore just embedding the video-track unmodified into the MP4 works great in most cases and is very fast and reliable. Nearly all MKV files contain H264 video-tracks, which is excatly the video-codec expected in MP4 files. Only the audio-track is often converted for increased compatibility. The video is taken as-is and embedded into the resulting MP4 file without being altered. The important thing to know here is that MKV2MP4 does not alter the video-track of a MKV in any way.
