“This video is not available in your country due to copyright restrictions.”

That, I suspect, is due to the background music. Fancy posting a silent version so people outside the US can have a gander?

Where are you located? I thought only GErmany had it blocked. Are you in Germany? Or for that matter, the EU?

Now it’s late and I’m tired but I’ll explain in more depth tomorrow. I use a whole bunch of programs, but the big one is avisynth. The despotting-descratching of the first movie clip was actually ridiculously complicated. It should be fairly easy using a filter called “despot” but the spotting was so heavy that getting the filter to do so also lost a lot of motion detail, which it shouldn’t do. On top of that the video had interframe blending in the telecine process which totally messed up the filter. To clean it I first had to de-telecine it, but I couldn’t get a good clean reconstruction of the 24fps frames.

What I ended up having to do was write a long script that first de-telecined it and then took the 24fps stream and broke it into two streams 12fps each – one for odd frames and one for even, and it had to do this in segments, using scene detection. So it took the two streams and alternated for motion mapping but used each stream individually for frame to frame temporal comparison. It used that for despotting (using several calls to the filter, each time with different thresholds for different size spots) and then interleaved the two and then finally ran the filter again on the interleaved stream. Then it still had some small problems and mosquito noise and a few areas of heavy grain. So after those filters, the whole stream went through a motion-compensating temporal denoise filter and a grain map denoiser.

Then after that, because the filter does not work properly on scene change frames, the first and last frame of each scene is dropped, which is completely unnoticeable, and replaced with a dupe.

That is pretty damn good. Actually, a couple are fairly remarkable. The ones that really impressed me are the old film spots and scratch removal and also the deblocking/compression artifact ones. What are your tools and how did you do that?

(If you don’t mind me asking. If it’s a trade secret I get it)
