unfortunately that one bored the hell out of me :( more pictures and faster slideshow would have made it a pigg ...

Really enjoyed this during the compo. Would love to hear more about the tech. Great soundtrack too.

@break: Screenmode is dynhires interlace, 16 colors of which 14 can be changed in the hblank. Color 0 is left black and some pictures have 1 or 2 fixed colors for aesthetic reasons. I do not calculate 14 fresh colors each line, but constantly reuse a K-Means' state. Input is a density function over line histograms with current line in the center. The K-Means is enhanced with motility/inertia factors per cluster, which are updated/fed-back from the number of pixels represented by them, so clusters have strong tendency to change little, sort themselves by popularity and into the same palette indices. So I get tightly packed line palettes (often only a handful minimal changes per line), and after render/dithering, 4 bit color indices. As Blueberry suggested, the color indices then undergo Move-to-Front transformation before entropy encoding. This idea saved the project 1 week before Deadline, but luckily we also had a canonical encoder and fast 68k Huffman decoder lying around, and MTF transformation is no big deal with only 2.7 bits per pixel on average. (The first picture is unpacked for getting the show up as quickly as possible, this drags down average compression.) The sync is factored around almost constant decrunching, the exact images and order were given by the art department. The music is a regular PT mod.

Thanks bifat, very interesting and the results looked good indeed :)

Very lovely and it has nice mood! I especially enjoyed the soundtrack growing towards the end, made it intense. :)

nice pics and so lively for OCS
so the next photocompo will be held using a a500? =))

I like the concept and the pictures. Having heard about this project some time ago, I was looking forward to seeing it completed.

Some more variation in the music could have underlined the mood of the pictures better.

Something to calm down ain't the worst you can get nowadays, though a slight faster smooth pacing could've helped

little faster pace would have been a plus

Minor fix available - now loops on real diskdrives without lambasting the stepper motor (this went unnoticed when coding against an USB drive, now I got hold of an Amiga with a real diskdrive again).

Nice photos.

Great copper display tech! looks like truecolor images. Must have taken a lot of tweaking to get it to this quality.

Magical resolution!

Really impressive to watch this on my A500.

Nice calm slideshow :)

Great interlace stuff. Been wondering if the interlace flicker could be reduced by having fields properly signal processed

bifat: very cool image codec. I like the work you did to minimize palette changes from one line to the next. It'd be interesting to try encoding the mtf transformed indices with an arithmetic coder (adaptive or otherwise), see if another smidge more ratio could be squeezed out :)
