[FFmpeg-user] Tag mp4s incompatible with output codec ?

Thanks a lot for your response.

I have just checked; IIUC, -sn would omit the subtitles in the output - is that correct?

OTOH, as far as I can see, the video does not have any subtitles.

I have also tried your suggestions, like this:

I must be using the option -sn wrongly.  What is the correct way?

Thanks a lot for the hint.  I tried this :

% ffmpeg -i "Neuroscience of VR, Congruency, pain distraction, presence, Enfacement effect, rubber hand, tools as part of the body, redirected walking - Bruno Herbelin, CERN, 2017.mp4" -map 0 -c:s copy -map_metadata 0 -map_metadata:s:v 0:s:v -map_metadata:s:a 0:s:a -c:a aac -b:a 128k -codec:v hevc -tag:v hvc1 -preset faster -crf 25 -profile:v main -x265-params "me=umh:subme=5:ref=4:aq-mode=2:aq-strength=1.0:psy-rd=2.0:psy-rdoq=1.0:rd=6:log-level=1" -f mp4 "Neuroscience of VR, Congruency, pain distraction, presence, Enfacement effect, rubber hand, tools as part of the body, redirected walking - Bruno Herbelin, CERN, 2017.mp4_converting"

But I get the error message 

[libx265 @ 0x7fbae600ce00] Unable to parse option value "main"


Maybe, I've got an older version of ffmpeg.
