Hi,
I was thinking about testing various denoisers in vapoursynth with 4k, 16 bit camera footage, and took a look at Tears of Steel (for example https://media.xiph.org/tearsofsteel/tearsofsteel-4k-tiff/), however this Sony F65 footage looks like crap to me. It's noisy and posterized even in bright light. I wanted something noiseless that I could add synthetic noise to to see if denoising can retain details.
So I'm looking for something more modern, perhaps Red footage? I'd like to get the raw film frames (exr, tiff, doesn't matter), a scene with a sharp, in-focus closeup with details, and little noise.
Was planning on adding a really good film grain, not the fake type with script approximations, and also digital camera noise, to see how denoisers handle the two types.
*for an example of how bad it is, see https://media.xiph.org/tearsofsteel/tearsofsteel-4k-tiff/graded_edit_07630.tif It'll load directly in windows, and loads in Gimp. Either way, posteration on the side of his face, lots of noise in the blurred out background. Colour noise on his stubble.
