Site updated!!
look at:
http://ragozini.googlepages.com/vdpenc
Now VDP limitations are taken into account, but the k-means and the VDP "quantization" are in cascade
I need to speed up a lot the VDP "quantization" in order to include it in the k-means loop
only in this way we can really improve WRT the standard bmp->scr2 converters
BTW, how does the preliminary result look like?
IMO it looks non excellent but convincing ...

The right side should be pure MSX1 screen2 !!
(at least I did my best to include in my code all the limits of MSX1 - tell me if the color clash and the palette are wrong)
PS
the msx1 palette i use is (in RGB) :
pal = [ 0, 0, 0
0, 0, 0
0, 241, 20
68, 249, 86
85, 79, 255
128, 111, 255
250, 80, 51
12, 255, 255
255, 81, 52
255, 115, 86
226, 210, 4
242, 217, 71
4, 212, 19
231, 80, 229
208, 208, 208
255, 255, 255 ];

Well I'we found a small bug :-)
The screen 2 tiles are rotated 90° vertically, so the 2 colors in 8 pixels apply on vertical 8 points in each 8x8 block...
As soon I correct the problem I'll post new results

IT's a video encoder that optimizes the pattern table usage.
IT's idea is based on the utopia demo from dvik and joyrex. |

And it makes videos possible on MSX1 machines at a decent framerate, right? Using little data?

Yes! Using the same tileset (3x2 = 6K) you can encode 12 frames at 768bytes each (or less if you use dfferential encoding across frames)
