Default settings for the Denoise: Quantization filter

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.

As far as I can tell it was an arbitrary default or perhaps I based on some experience now unknown. This is based on a FFmpeg filter whose default value maps to 23% in Shotcut. I have changed it to your suggestion of 3% for the next version 25.10 (not beta).

Thank you. Just a few more seconds of time saved :slight_smile:
