Downloaded and converted a copy of Rick Astley's popular music video for the song "Never Gonna Give You Up". The screenshot gives the basic gist of what you'll be looking at, the .8xk download is the first 5000 (of 6,392) frames (roughly 2 3/4 minutes long)

On-calc filesize is 966,656 bytes (944KB). SPASM refuses to compile the entire video (it crashes if attempted).

First 5000 frames because it was a nice, easy number to pick that would still compile. The original video would've spanned 72 pages, and SPASM crashes on attempting to compile that.

Note that there is no real audio, but if you try anyway, you'll end up with a low pitched hum (since the audio driver is never disabled)

Any suggestions on other videos to try?

I had the same problems with Spasm, so what I did was save the additional pages as .bin files (I had my Python encoding script output them), had spasm assemble the first page as another .bin file, and then concatenated them all and signed it with Rabbitsign.

maybe you could cut out every second frame?

Awesome. Now if only the rickroll had sound


Do you think you could do this with Zelda: Dark Link Quest's final boss intro? (Although it's about 6 FPS)

The grayscale is a side-effect. I don't have anything at the moment that could make something like that intentional.

EDIT: Darn it. Now you've got me thinking on how to make it intentional. And to support dithering and other image manipulations in-app.

We need a compression routine which supports dithering. Bitmasking?
