This might be a suggestion, but I just want to start with an observation and a question.
When I use the Denoise: Quantization filter, the default strength is set to 43, which works basically just as a giant blur filter (something like the current “AI” video “optimisers” are likely to produce, or worse). Is there a reason for this?
I have to denoise old and noisy stuff quite a lot, and in my experience a default setting of 2 or 3 would make much more sense. I also rarely have to/can go beyond 10.
