Some video cropping snippets using ffmpeg.

ffmpeg -i input.mp4 -filter:v "crop=2048:1536:256:32" output.mp4
# Center video onto 1920x1080 canvas with white background

exiftool -TagsFromFile a.jpg b.jpg
# Photos — change CreateDate metadata
exiftool "-CreateDate=2017:05:17 12:00:00" IMG.jpg
# Videos — change date to "Creation Date" (written by DSLRs)
