Could you share the full terminal output rather than only this part. I suspect your copying an audio encoding from the input to output that QuickTime doesn’t support, but there’s not enough clues to see that. If re-encoding the audio is acceptable, then replace -c:a copy with -c:a aac or another audio encoding that QuickTime will support.
