Help regards denoising

[Soloiam68]

Does anyone know how to improve motion scenes while degraining with something like MDegrain? It's a temporal denoiser that works great, but it doesn’t handle motion scenes very well.

Recently, I found what I think is the best denoiser QTGMC. It handles motion scenes well, but its built-in denoiser doesn’t fully clean most of the noise (it blurs a lot if the value is set too high). Additionally, it’s primarily a deinterlacer, which has its own downsides when working with progressive video.

is there any script that uses algorithm of QTGMC and uses that on a simple temporal denoiser to detect noises

Just so you know, the degraining in QTGMC is done by MDegrain. ;)

When using MDegrain, it's all about tuning the settings. The programmer who built the QTGMC script was genius and spent a lot of time getting things right, but it isn't always the best thing for a particular video.

When doing any sort of noise reduction, you have to do your own tuning because each type of noise is different. MDegrain, whether you use it yourself, or use it inside of QTGMC, is not always the best solution.

There are hundreds of denoising threads in this forum that you can read in order to find the best denoiser for your particular video.

You can try M_QTGMC with medium or high settings to see if it will help with motion scenes. But its defaults params to underlying QTGMC may not include all required for denoise - you need to check and add to M_QTGMC function is something is missing. It includes some latest build of mvtools2.dll with many new features for better MVs quality at motion and also some way to extract more details from several QTGMC calls with different set of params.
