Depends on at least three things. Is the LUT made for limited or full-range input/output? Is the source limited or full range? Should the output be limited or full range? 1) Input, in my case, is PQ video from UHD, so we can assume it's limited range. 2) My LUT wants full range. 3) The output shoul...

Let's test what we have and I'll look into the range stuff in parallel. In the examples you write: loadplugin("...\dgdecodenv.dll") loadplugin("...\dgcube.dll") dgsource("THE GREAT WALL.dgi") DGCube("PQ_to_BT709_slope.cube", fullrange=false, interp="tetrahedral") What is the output format and range...

Perhaps you already know but LUT cubes can work in RGB or Studio RGB, i.e. full TV range or limited TV range. On PQ to HLG, for full TV range, such as BBC ones, you would need: #From 4:2:0 16bit planar Narrow Range to RGB Planar 16bit Full Range z_ConvertFormat(pixel_type="RGBP16", colorspace_op="20...

That was all done in C code. Now I'll port it to the CUDA kernel. That should be plain sailing.

Eager to test it.

Sure. Bullwinkle already mentioned that.

And it gives a raison d'etre for DGCube.

Do you think it's possible to have the necessary color space conversion ported to CUDA, to offload the cpu as much as possible?

OpenCV supports it easily and, if I am not wrong, it's written in CUDA... so...

Please let the Doom9 guys know about this.

Your wish is my command.

P.S: Will you add tetrahedral to AVSCube too?

I compared scripts with BlankClip() source and no conversions and things are as expected.

Please, post your script.

Re-download DGCube to get the fix, i.e., ability to open any size cube file.

Rapidly tested and it seems to be working.

I will bench and post results.

Your cube is size 33.

Is the 65 size related to CUDA only? AVSCube works ok.

1. Where are you loading avsresize.dll? No need as it's in AVS+ default folders. 2. Can you give me the cube file? I can give you a identity one, that crashes too: IDENTITY.7z which must be size 65 Are you meaning kB or what? Both BBC and Warner Bros licensed cube files are around 1 MB. I asked a f...

Thank you for the link.

Thanks for your efforts.

It would be nice to have some of your results with cube (avs and cuda) + mvtools + x265 --preset slow, to simulate real world sets. I don't know with your processor but some offload of a very intensive task can be really useful.

Here's DGCube

Great! Does it follow the same syntax of AVSCube?

I tried! You are considering a modern CPU as reference for your benchmarks. I am running on a museum ready i7-2600k... do you think it could keep up against CUDA? :D Moreover, did you try to x265 encode at the same time, instead of just measuring raw cube mapping performance? I think that is the fi...

My initial idea was to have HEVC 4:4:4 not to encode movies, as there are almost none, but to ...
