 This is so many things wrong with this: while mp4 converts FLAC (from your
 source nut file) to aac, mkv converts it to Vorbis (also mp4 does not
 support flac, only with -strict -2 -c copy it will work, while mkv
 converts it to Vorbis of all things, while it supports flac). But because
 flac from your file is very interesting as it is longer than video:

 Stream #0:0: Video: h264 (High 4:4:4 Predictive), yuv420p(progressive),
 1920x1080, 24 fps, 24 tbr, 1k tbn, 48 tbc (default)
       ENCODER         : Lavc58.91.100 libx264
       DURATION        : 00:01:08.459000000
   Stream #0:1: Audio: flac, 44100 Hz, mono, s16 (default)
       ENCODER         : Lavc58.91.100 flac
       DURATION        : 00:01:08.470000000


 it breaks mkv. Well...
