I have worked for few months just the Prove It All Night from Largo 1978.
It's still far from finished. Here's work in progress:
left is the 1080p remaster, on the right is my 4k version with QTGMC -> VEIA 100% denoise -> VEIA 4k upscale. Still missing color correcting, sharpening etc..

Not entirely happy with the results, but it's getting there.
