[HELP] Fragments disappear in hand-drawn animation

[Dmitry]

Thanks! And in the case of sample 5, which is better? What settings should there be for filters? And where to find DPIR deblocking? 
As I understand it, DPIR is needed only on a very noisy picture, what in other cases? And I tried cutting the video in parts, for sequential processing. This increases the time, but does not overload the equipment.

No video cards have become very expensive lately. I bought the option that was optimal in price and quality. The only drawback, yes, there is no cuda here and working with rays is worse.
