How big are those files going to be without compression? one HDD per film? ;P
It's only for (motly silent) cut scenes in my HD games based on films/TV shows etc one day, for now. (320x150x6)/8= byte size of frame. So 48000b for 4096 colour frame but you get 250% more resolution & 24/25fps image with no 'noise' over smaller CDXL files. You can tune the compression into playback after you benchmarked the chipset bus DMA throughput for OCS. I want to try lo-res interlace too actually

The whole point was to show Amiga 1000 was massively held back by storage technology of 1985 NOT OCS ie 1-2 decades ahead of it's time in potential. And that 7mhz A1000 movie will still look better than VGA ISA 486 25mhz 256 colour dithered animations thanks to HAM mode.
If nobody ever used it I wouldn't mind, it's for my own personal projects.
