Earlier I was a bit concerned about whether an external Avisynth+ filter could change the video format, e.g., from YUV420P16 to YV12. Then I realized that is exactly what z_ConvertFormat() does. So I tried it and it is actually quite easy. So I now have a filter that just converts YUV420P16 to YV12 ...

OK, good to hear. Of course, there are a lot of ways to map the out-of-gamut values back into range, but it seemed sensible to me to just reverse what is given for 709->2020 in REC 2087.

So, we have established that we need to do the 2020->709 conversion and the tonemapping all together on the GPU if we expect CUDA to give us good performance gains. So I have been researching how to do that. Here is my tentative plan for the 2020->709 part. If it pans out then tonemapping can be add...

64 PCIe lanes. Now you're starting to get my attention.

Thanks, I'll study that carefully.

Eeww, AMD? Are you sure?

Good to hear and thanks for the update.

You should be really envious of gonca's CPU.

Waiting for Volta...

If you'd like to give me a sample I can test it on my 1050 Ti and 1080 Ti.

Yes, please provide a sample of the source video that shows these errors and tell me how to duplicate your issue.

You are welcome. It's always my pleasure.
