Re: HDR -> SDR tonemapping
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 ...

Re: HDR -> SDR tonemapping
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...
