LOL... I didn't realize SU meant that superuser page. Haha! I think it would be very helpful if you updated that page because it comes up a fair bit in search results. :-) That's too bad that episode_sort can't be changed to a string but if it can do a full 32 bits that might resolve the issue. I just tested adding a custom tag and it worked. It also shows in ffprobe. Yeah!! So this worked for me: ffmpeg -i input.mp4 -metadata media_type="10" -metadata title="Law & Order" -metadata show="Prescription For Death" -metadata season_number="1" -metadata episode_id="66209" -metadata episode_sort="1" -metadata:s:a:0 language=eng -movflags use_metadata_tags -metadata episode_number="Episode 1" -c:v libx264 -c:a aac output.mp4 ffprobe shows in the Format section: [FORMAT] filename=testoutput.mp4 nb_streams=2 nb_programs=0 format_name=mov,mp4,m4a,3gp,3g2,mj2 format_long_name=QuickTime / MOV start_time=0.000000 duration=3254.063000 size=213344376 bit_rate=524499 probe_score=100 TAG:minor_version=512 TAG:major_brand=isom TAG:compatible_brands=isomiso2avc1mp41 TAG:episode_number=Episode 1 TAG:media_type=10 TAG:title=Law & Order TAG:show=Prescription For Death TAG:season_number=1 TAG:episode_id=66209 TAG:episode_sort=1 TAG:encoder=Lavf58.13.100 [/FORMAT] This is fantastic!! No metadata limitations. :-D :-D Is this all in the official ffmpeg documentation? As mentioned I couldn't find anything and I searched through all of the references for metadata but it's possible I missed it. At least this answers my questions and solves my problem. Thanks again Gyan!! Cheers.
