How to enable GPU for MCTemporaldenoise filter?

[Toothache]

My input file is an 8 bit x264 YUV, not RGB. I'm encoding it to 10 bit x265, is that what you meant by high bit depth?

The important question is what color space and bit depth the content is in the filter chain when fed to the filter.

Oh how do I determine that, what the color space and bit depth are?

I just tried the KNLmeansCL using the last build you sent me - while it doesn't crash anymore, I don't think any denoising is being performed, when I set the channels to UV.

Also - similarity radius can't be increased beyond 4 in Hybrid, while the developer of KNLmeansCl had stated that its maximum value had been increased to 8 some time back.
