# 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

This is what I've been looking for. I just need to figure a couple of extra things out. Is there a way to have this script also keep the original file modify and file create dates, and also to bring over the original files exif data such as location and any other info?

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.
