True, but I'm trying to get a specific codec (h264) so that it will decode
on my Raspberry Pi properly, and I want to keep everything else the same,
that's why the -c copy.

The reason I need to do the image sequence is because the image upconverter
*isn't* in ffmpeg, and can't do what it does.  I'm not just making the video
bigger in size, I'm increasing the quality, and making it better than it
was.  There are some good example images on the main projects website here:
https://github.com/nagadomi/waifu2x It uses a Deep NN to render the images,
and it takes a bit to render a few hundred images, even using a GPU.

Either way, video -> image sequence -> video doesn't work, without doing any
kind of conversion in between.  That is my problem.
