I recovered my old Technicolor-look-a-like-more-or-less regrade of A New Hope made two years ago, and upscaled the regraded HDTV using this technique:
comparison: http://screenshotcomparison.com/comparison/131279
test clip: http://www.filedropper.com/anhuhdtest (again 10s, it takes so long to make it!)
Guess I went too far with the highlight, clipping some whites.
So, if someone downloaded the clips, how do they seem? Too fake, plastic-y etc. or watchable? Thanks for the feedbacks!
