Some video cropping snippets using ffmpeg.
# Crop to 1240x768 (tablet) on retina screen
ffmpeg -i input.mp4 -filter:v "crop=2048:1536:256:32" output.mp4
# Center video onto 1920x1080 canvas with white background
ffmpeg -i input.mov -vf "scale=min(iw*1080/ih\,1920):min(1080\,ih*1920/iw),pad=1920:1080:(1920-iw)/2:(1080-ih)/2:color=white" output.mov

Useful metadata editing and batch renaming snippets using exiftool.
# Changing metadata -----------------------------------------------------------
# Copy tags from one file to another
# http://thomer.com/howtos/copy_exif.html
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)
