ffmpeg can produce PNGs, one per frame, and convert only a few specific

There's a couple of variants for comparing images.
compare foo.png bar.png x:
gm compare -highlight-style assign foo.png bar.png -file x:
Hi Ralph
Would you first need to convert the H.264 or H.265 to raw video? If one
PNG is of an I-frame and the next is a P-frame or B-frame they are bound
to be different.
Best wishes
