yeah, I after I wrote those paper authors I also wrote the slide author - who is the only one who emailed me back, so I got the slides.

Still, I think more information is recoverable. For example I could tell Video Enhancer wasn't using that many frames (from the encoding progress and framerates), maybe just a few adjacent frames.

Yet you could see a very clear improvement:

(As though a sharpen mask was applied, but it isn't.)

I did see if I could get an improvement if I forced it to use more frames by running through a few times, each time doubling video speed so I end up with 1 frame from the whole segment - but it didn't end up better. Anyway, now I have the original.
