with rotation

Use -vf "transpose=2" 0 = 90° counterclockwise and vertical flip (default) 1 = 90° clockwise 2 = 90° counterclockwise 3 = 90° clockwise and vertical flip

find * -type f -name '*.MOV' -exec bash -c 'ffmpeg -y -i "$0" -c:v libaom-av1 -crf 30 -b:v 500k -vf "transpose=2" -map_metadata 0:s:0 -metadata language="ru" -metadata title="${0/.MOV}" -metadata creation_time="2015-06-26T00:00:00.000000Z" "${0/MOV/webm}"' {} \;

Change meta only

For single file

Tip1: copies all global metadata `-map_metadata 0`

ffmpeg -y -i '/home/a/mystorage/terinyLoveMusic/dropbox/ballroom dance/convertMe2/metaChange/Бал-презентация '\''Надежда, Вера, Любовь 2017'\''.webm'  -c:v copy -c:a copy -map_metadata 0 -metadata language="ru" -metadata title="${0/.mp4}" -metadata creation_time="2017-04-08T12:58:01.000000Z" '/home/a/mystorage/terinyLoveMusic/dropbox/ballroom dance/convertMe2/metaChange/Бал-презентация '\''Надежда, Вера, Любовь 2017'\''2.webm'

Make the same datetime for all files in current folder

Direct way will not works because of "FFmpeg cannot edit existing files in-place."

find * -type f -name '*.webm' -exec bash -c 'ffmpeg -y -i "$0" -c:v copy -c:a copy -map_metadata 0:s:0 -metadata language="ru" -metadata title="${0/.webm}" -metadata creation_time="2017-04-08T12:58:01.000000Z" "${0/mp4/webm}"' {} \;

Add EXIF's ImageDescription based on current folder's name

exiftool -overwrite_original -ImageDescription="$(basename "$PWD")" "$PWD/"
fdfind -e '.jpg' -e '.jpeg' -e '.JPG' -e '.png' -tf --one-file-system --maxdepth 1 -x exiftool -overwrite_original -ImageDescription="$(basename "$PWD")" {}
