Part 5: FAQ on MKV to MP4 Conversion on Mac

Q1:I want to convert a mkv file to mp4 format 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.

A1: In MacX Video Converter Pro, tick on the box of Auto Copy. It convert MKV to MP4 without changing the underlying codec. Also, it can copy a large high-definite MKV 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. 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 extract MKv subtitles and convert them to SRT or burn subtitle to the video permanently.

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.

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.

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?

A4: iTunes supports video formats including MP4, MOV, M4V, limited types. You can change MKV format to MP4 iTunes acceptable format or directly convert MKV codec to iTunes profile. 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, 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.
