[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.
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.

Q4: I have a lot of HD MKV files that I wish to convert for iTunes. I want a converter, but need to keep the same good quality!! (the videos/movies are 720 and 1080p) Any suggestions please? OS X or Windows, I can use both. Linux too if it crops up..Thanks - Vortar from mac-forums
A4: You see, iTunes supports video formats including MP4, MOV, M4V, limited types. If you're itching to convert MKV to iTunes, one way is to change MKV format to MP4 iTunes acceptable format. Another better way is to directly convert MKV codec to iTunes profile, with iTunes best parameter settings. In case you are a layman and don't know much about iTunes suitable video parameter settings, you'd better resort to the MKV to iTunes conversion with most ideal profile offered.

Q5: Hi anyone know who is best .mkv to .mp4 video converter with high quality video and audio and low Mb size so if its possible. Now I'm using Handbake to convert a 4K MKV file but it takes much mb size (10 mins for 1.5GB). Which will give me the smallest output size with best possible quality?
A5: First of all, you should know that file size = bitrate * running time, and bit rate will influence the video quality. If you don't nitpick the video quality, lower the bitrate and resolution to one level below will result in smaller size with acceptable quality. Beyond that, editing features like cropping and trimming will also help. Put aside the objective factors, software design will lead to difference in output size. MacX Video Converter Pro has a unique compression engine which will be worth your try.
