@Chillheimer:
Your slomo is quite interesting, the way the palette moves seems to enhance the 3d effect as if the pattern is pulsing without shifting the colours too much. I do spot some jumps in the palette but maybe that's youtube recoding stuff as it always does. Recoding works best when providing lossless source and I'm not sure if youtube is willing to recode **huge** h264 lossless source videos.
edit: your slomo is more than quite interesting, how much patience would one need to render a 4K video of 24hours long with such antialiasing? Just think of the weeks of encoding to pristine h265... I'd be doing that in the winter time because it might increase the room temperature :-)
About colour perception and testing if one has 'perfect' colour vision. I think that setting up a good and unbiased test could turn out to be not too simple.
Sometimes green can be yellowish or blueish without actual changes to the actual colour pigment/pixel itself.

I have cancelled the slope thing and continued the same zoom without slopes. I've completed 7680x4320 .kfb's, rendered those to 1920x1080 (for antialiasing) with 900 frames per .kfb file, using Lagarith as codec. Another reason for me to not encode to mpg immediately, is that with Lagarith I can jump to any frame without waiting for virtualdub. So it's practically like random for me, I just click somewhere in the timeline and the frame immediately comes up.
I'll be sharing 12 movies using bittorrent, varying the following properties, all the same very boring zoom from .9 to 1.23e27 (see source below):
- 1920x1080 resolution (h265 codec) versus 1280x720 (h264 codec)
- 'original' slow motion (45m20s) versus factor 9 speedup (5m02s) versus factor 18 speedup (2m31s)
- constant quality ratefactor 19 (higher fidelity and bigger filesize) versus constant quality ratefactor 22 (smaller filesize)
Any 'big' file will have a .mkv containers, smaller ones like the x18 speedups are all .mp4.
The failed slope piece will also be available, probably as h264 .mpg just for showing why I cancelled the slope thing.
As it seems, using 870x4320 .kfb's as input leads to 'slope' jumps every 'keyframe' so for me each 900 video frames.
I've have tested this with 2.7.9 KFF with the KFM version of that time. Could be that using latest KFM doesn't have this issue.
If requested I'll provide the 91 .kfb files involved (7680x4320, slopes included) on bittorrent as well. I do have the equivalent .jpg's of that same resolution, included the failed ones at the beginning of the zoom (low zoom factor).
All .kfb's have been rendered with max iteration fixed to 15000000.
I guess that apart from slopes, I'll be working on finding an acceptably easy way of getting rid of any colour banding. Using a bit of noise for that is supposed to do the trick, as it should be smearing out the rounding errors that you get when throwing away (colour)bits. By smearing rounding errors, the average rounding error per pixel per frame can remain unchanged while our brains have a harder time to notice the colour information loss.
Videos with slow position /colour changes to large surfaces with shallow gradients suffer the most of colour banding I think.
