Full motion video on C64
Any examples? Wildfire is one, I am just writing an article regarding the different full motion video techniques that are feasable and doable on the C64. These include the standard 40x25, 80x50 fli, interpolated by look up table, etc etc
I am working on a PC Vector quantization video converter which will generate 256 characters which best match the video sequence. so in effect each frame will take up 1000 bytes using the same 2k char set.
Demo may be released some time soon..

Any links to the weekend demo? or screenshots. did it use an entire (2k) charbank for each frame?
it would only result in max around 20 frames on c64 single load though |

I have thought about the same, but I think it's a bad idea to use a new charset for each frame, since that would make each frame take up 3K instead of just 1. Instead I would have a few different charsets, and then switch it every 8th rasterline to the charset that fitted each char line best.
A good way to reduce the char errors is probably to blur the whole thing heavily before packing. |

4 charsets, lousy best fit, and shuffling of the lines of the chars after conversion: k-bit 2006 |

@hollowman - nice work on k-bit! Great design as always :)
@algorithm -
Effluvium packs in 120 frames by defining each frame with tile indices rather than characters. It does make the player considerably more intensive though!
Only one cset is used. |

probably.
anyway since some years my rule of thumb for choosing demonames is this:
1. make it short
2. easy to remember
now sphaeristerium is anything but a good choice marketingwise :) |
