Most editing software don't read Matroska files. And if the container is
MOV, non-Mac editors usually rely on antiquated 32-bit Quicktime to open
the file, whereas they normally have native MP4 demuxers. And some
editors don't skip the priming sample in AAC/MP3 streams causing a
desync - in which case PCM is preferable.
