【Update】 Questions & Answers to MKV to MP4 Conversion on Mac

Question 1:
Converting MKV to MP4 fails. Hello, I'm trying to convert an MKV container to MP4 / M4V while maintaining 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. The problem is that the resulting M4V output file contains only the audio track; the video is missing. If I use the "Streaming/Exporting Wizard" instead of the "Convert/Stream" function, 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! - cinergi from forum.videolan

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 converting MKV to HEVC x265, you're suggested to ditch away VLC player, instead using the advanced MacX Video Converter Pro to convert MKV to HEVC x265.
