OT: Cool photos! Michael, what lens
did you use? An 8mm? If you don't
mind me asking.

ffprobe reports:
    Stream #0:0: Video: mjpeg, yuvj420p(pc, bt470bg/unknown/unknown),
5472x3648 [SAR 72:72 DAR 3:2], 25 tbr, 25 tbn, 25 tbc

But I guess we already knew that from
your error message as Moritz said!

If you wanted to convert it back this
could work?

$ ffmpeg -i IMG_044.JPG -pix_fmt yuvj422p IMG_044-yuvj422p.JPG

The resulting difference is almost invisible:
