MKV is a wrapper, not a codec

MKV can hold almost anything: H.264, HEVC, VP9, multiple audio tracks. Phones and many editors only want MP4 with H.264 plus AAC.

When the video is already H.264, we remux into MP4 without touching the picture. That is why a 2GB MKV can become an MP4 in seconds.

If the codec cannot live in MP4, we transcode with the hardware encoder. Extra subtitle tracks are not copied — burn them in an editor first if you need them.
