There are anyway jaggies artefacts visible in last example from Avid. It looks "better" because it is a different scene with less clipping, less contrast.
No the still with grain is a quick and dirty approximation of where it's ending up, how it looks best to me, your examples just look over processed for me. The last examples are definitely mapped 16-235, they are not remapped but they are not graded or clamped to legal levels, so the gamut may exceed those levels. Yes Avid converts from 601>709, when you change format, so of course there is a shift from the original. I only sent pngs on the first lot.
The real problem is Hybrid's not working for me on Windows - I've followed your instructions to the letter but output files just keep on growing with no end until I kill them. I've decided just to deinterlace in Avid, export SD to Resolve Studio, via AAF, superscale, denoise, sharpen, CC, grain etc., back to Avid for online finishing, export.
"over TV and film for over 30 years", yeah great.
Sadly it's all too true. But if you're suggesting I'm clueless, then maybe you're right but I'm not a compression specialist, so I claim immunity
I do really appreciate your help though, thanks.
Hi Steve, here is another version (different algorithm):
Thanks Uli - I'll have a look
