# Extracts the MP4 video component of Motion Photos introduced on the
# Samsung Galaxy S7. Uses exiftool to get the job done. Ignores files
# that do not contain motion photo data. Unfortunately, exiftool does
# not yet support removing this embedded data from images.
# See http://www.sno.phy.queensu.ca/~phil/exiftool/TagNames/Samsung.html
#
# Example usage: extractMultiPhotos.sh /my/photos/*.jpg

Hi Wesley, you could definitely set the file’s filesystem timestamps with the touch command. I don’t know of a way off the top of my head to directly copy over all the EXIF data but if I had to guess exiftool would be capable.
