[Update] FAQ on MKV to MP4 Conversion on Mac

Q1:I want to convert mkv to mp4 without re-encoding to keep the same file size and video quality. I need a program that allows me to just drag my 720P MKV video file onto, set it to mp4 and get the file with no quality loss. Any help?

A1: If the video streams in the MKV file are in an mp4 compatible codec like H.264, then you can move content from mkv to mp4 intactly by simply changing the format. In MacX Video Converter Pro, the Auto Copy box on the right lower interface is designed for that job. There are many other demuxers on the market for the same task. An extra benefit is that it can copy a large high-definite MKV to MP4 few hundred times faster than re-encoding.

Q2:I have a MKV file with subtitle muxed, now i want to convert it to mp4 without losing the subtitle. I already tried the other softwares like Handbrake, rebox.NET and VLC to convert it but the subtitles didn't carry over.

Mkv To Mp4 Online

A2: It will depend on the type of subtitles. You should note that MP4 supports less types of subs than MKV. If the subtitle is in XSUB, SAMI, MPSub, SubRip or others, you can't pass-through the subtitle into MP4. To keep the subtitles, you can either: 1; extract the subtitles out of MKV and convert them to .srt format. 2; go to handbrake, select subtitles tab, select the subtitle track and then burn in the subtitle. With MacX Video Converter Pro, it will pass-through supported subtitles from MKV to MP4 as soft subtitles, and automatically burn in subtitles to MP4 when it's not supported. Not o mention that this program can extract subtitles and save them in .srt format in one stop.

Q3:I'm trying to convert an MKV container to MP4/M4V with the existing video and audio codecs (HEVC x265 and AAC audio). I used the 'Convert/Stream' function and selected the 'keep original video track' and 'keep original audio track' checkboxes. But the M4V output file contains only the audio track; the video is missing. If I use the 'Streaming/Exporting Wizard' instead of the 'Convert/Stream', the MP4 output option is greyed out and can't be selected unless I enable transcoding to 264 (which I don't want to do). Any ideas? Running VLC 2.2.1 on OS X El Capitan.Thanks!

A3: The highest possible reason why you fail to convert MKV to MP4 on Mac with HEVC x265 is that x264 works fine in MP4 file container while x265 is not supported in an MP4 container, at least not in VLC. So if you insist on transcoding MKV to HEVC x265, you're suggested to ditch away VLC player, instead using MacX Video Converter Pro to decode MKV to HEVC x265.
