# ----------
# 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
