That Smooth Criminal and Beat It show very obviously their source material and the Beat It sadly the guy wanted to let you know it was him by overlaying his name throughout the entire video lol.
Wonder if they were originally shot on film, if so the Jackson estate (or whomever own them) would be able to order a real restoration. When you look at the quality of the 4K remaster of Thriller, which was clearly shot on film, the difference is beyond measure.
For the Thriller video, is it just the YouTube compression making it look bad, or is there some DNR? There is significant detail loss and a bit of waxiness, from what I see.
