So I love the idea of creating a database of deleted scenes that are finally fixed and cleaned up and can be used in edits/preservation going forward, or just for viewing.
So I got hold of the Rizzler Ebook and had a play with upscaling vid17_OnCliffAboveMosEisleyTunisia_ProRes.mp4 as an example.
I used AE to upscale from the SD quality video to a 4k plate using enhanced scale.
Here are some screens here: http://imgur.com/a/ipTEG
These are the most difficult clips where there is just no decent resolution available.
I want to get hold off the blu ray clips next and work on them.
