I’ll see about trying to upscale the plate later today/tomorrow, but if anyone else wanted to have a go at it, here is the Google drive link Poppa provided awhile back for the clean plate.
Hey, I found a few minutes! Uploaded the 4K backplate for the puppet show from sherlockpotter’s source to the same link. Thanks, sherlock, it is sooo much sharper. Honestly, it makes me want to remaster the film in 4K (hehe, in about 5 years).
I had to tweak the color slightly to better match the HD version we’ve been working with and got it in the ballpark, but it may need some refinement (and Hal’s LUT ultimately).
The trick to using sherlock’s MKV (which is great because it’s right from the disc, no conversion) is to use an app called TSMuxer to demux the mkv into just it’s video component, which was a .264 file. The .264 actually works in After Effects, but it’s a bit slow. I only needed a few frames so I just used it as-is. But you can also use (sorry MR!) ffmpeg to change the container from .264 to .mp4 using the code posted by sade1212: “ffmpeg -i inputfile.264 -c:v copy outputfile.mp4”. There would be no conversion so it’s incredibly fast and without any quality loss.
