TemporalDegrainV2

[rgr]

Why am I getting this error?

Both clips should have the same colorspace!

In the new version I get this error:

Rolling back to 2.6.3 solves the problem.

Yes, I just updated the file. Should be fixed now.

I found that there is a wierd inconsistent chroma shift for 420 sources. It can be upto half a pixel. Which means that when resized onto the luma, it will be twice of that.
From my investigation I found that it comes from mvtools MDegrain. I reported it here, you can take a look of the magnitue of the deviation there.

I thus decided to go back to a single degrain step for the chroma. I think this is the best compromise in total.
This halfs the shift introduced by mvtools, which I think is good enough. And it gives quite some speed increase, at the expense of a slightly less clean chroma.
For the paranoid among us, a complete the circumvention of the chroma shift bug can be enabled by the flag "degrainAvoidChromaShift", but that is relatively expense at 10% performance cost.

Also, if it is really necessary to clean the chroma more, which should be rather rarely, both degrains steps can be enabled for the chroma by the flag "degrainChromaTwoStep". This will however also enable the relatively expensive circumvention of the bug.

thanks for v2.6.6! Can it ported in G41fun.py Vapoursynth? Its actually v2.6.3

I have abolutely no Idea how to do this, even with googling, maybe i only need to adjust some lines? they are very different AVS and VS codelines.

Can you have a look into my G41Fun.rar to show us how to adjust it, so i can use v2.6.6?

Im using Staxrip and i already just Copy & Pasted the entire TemporalDegrain2 code from another G41fun.py into this one and replaced it from an old v2.4.3?. Improvising

I'm Trying the filter for the first time, i get an error (for a change) (tried v2.6.2 and v2.6.3 aswell)

avisource
convertoyv12()
TemporalDegrain2("CUDA"=false)

script error expected a , or )

CUDA=false , no ""

TemporalDegrain2(CUDA=false)

Cuda parameter only use with postFFT=5. You can use without postFFT=5 but that parameter no meaning when don't set postFFT=5
