I'm "DevMonkey" on discord, and have been following your progress.

I've done alot of tests using tiles/bitmap/sprites for video it always comes down to bandwidth from sd-card.

also I forgot to note, you can press SPACE to pause and ESC to exit

I've come to the conclusion that SPRITES are the best frame vehicle unless the Video is either 320 or 640 in width and can be blasted to VERA without scanline math. The Sprites allow that if set up contiguously in memory. TILE mode may have some application but it seems to me that would be highly custom and I for one would have a hard time figuring out a generic conversion routine.

Using Try It Now, the resolution was horrible, but the audio and flow worked great.

Agree :)

Still working out resolution vs colors vs....w/e
limited bandwidth, so trying to maximize what can be done in it's limits.

Thanks for testing

I've done a number of these over the years. The main bottleneck is getting data from the SD card to VERA. I've managed 20fps for a distorted image (2.35 to 1 converted to 160x32 pixels, then using VSCALE to stretch the vertical back to proper proportions). I've got some ideas for converting video to double PETSCII, perhaps with a special character set.
