# For mp4, the recorded date can exist as Recorded date or Tagged date. If you want to do this for all the files in a folder, use the following command:
for file in *.mp4; do touch -t "$(mediainfo "$file" | grep --color=never -iEm 1 '(Recorded date|Tagged date)' | sed -r 's/.*([0-9]{4})-([0-9]{2})-([0-9]{2})[T ]([0-9]{2}):([0-9]{2}):([0-9]{2}).*/\1\2\3\4\5.\6/')" "$file"; done

# Some videos will not have that date in the metadata, so you'll have to correct it yourself
touch -t CCYYMMDDHHMM[.ss] file.ext
