It seems the input is ProRes with PCM audio that mp4 does not support? So
the copied audio might not work for mp4.

Try this (modify -crf and -preset and audio options from their defaults if
needed. Oh, YMMV if you insist on some bitrate):

ffmpeg -i input.mov -c:v libx265 -crf 28 -preset medium -timecode
00:00:00:00 -tag:v hvc1 -c:a aac -b:a 128k output.mp4
