Noise quantization

[Stefan_Holst]

Hi Shotcut friends!
I cant find out how the new filter “Reduce Noise Quantization” works.
How does it differ to Reduce Noise HQDN3D?
When to use which or used combined?

I suppose I missed something in the forum about the new filter or a request for it?
Found this for Reduce Noise HQDN3D and Wavelet Video Filter.

Reduce Noise: Wavelet Video Filter

This filter is available since version 20.06. About wavelet denoising Wavelet denoisers are excellent when decent-bitrate footage comes from a decent-quality camera, and the only real problem with the footage is high ISO noise or high thermal noise or photon shot noise. Wavelets are great at targeting inconsistency at the pixel level, as opposed to algorithms that average patches or regions, and end up smearing pixels in the process. A nice side effect of this precision is that gradients (es…

It is based upon this post and see its related post

QML for filters that don't have UI yet

I just want to do FSPP since it takes care of “my couch noise”. If I figure it out I could do the rest of PP filters that I did screenshots for in linked post, if there is an interest. I am using HQDN3D as a reference.

That comes from the underlying FFmpeg filter fspp

I renamed it in Shotcut to something less ambiguous than “post-processing.” In Shotcut, it always operates in constant quantization mode since the editing engine does not make the source quantization factor available. I recently used it to reduce noise on my Super 8 transfers.

Is it possible for you to make a description of your work flow and thoughts about settings of the noise reduction?
I will also eventually digitize my father’s Super 8 60:s and 70:s family movies.
