The result is very similar, but qtfaststart takes an existing mov file and
only moves the index in front of the file, leaving everything else exactly
identical while ffmpeg -i input -movflags +faststart out.mov writes a
new file (with different properties) that has the index already moved
to the beginning of the file.
