short: no clue
longer:
I only used ddcolor so far on a few small samples.
I saw such flickering with other colorization methods (like deoldify) too.
Given that ddcolor is rather slow (at least on my system), I would recommend to:
1. first try to find good ddcolor settings
2. export to a lossless format
3. take that as source and try to stabilize
No clue how to stabilize these flickering, I would be surprised if any of the filters currently in Hybrid could really help with this.
Maybe looking the output in 'splitYUV' can give some inspiration.
First thing is probably trying to get a feel for what triggers the flickering. (if smoothing the source strongly before applying ddcolor would help, one could later write something to take the UV channels from a smoothed source and Y from a sharper version,..)
-> no clue,..
Cu Selur
Ps.: main problem is that all the coloring stuff I'm aware of is meant for images and thus has no temporal awareness and the used models are not trained on much data.
PPs.: compression artifacts might also improve the problem, looking at your file with retinex enabled, it's quite blocky.
PPPs.: attached a colorized version (script used: https://pastebin.com/qHnpa81b), I doubt that this can be really color stabilized.
