Here's an idea for the next round of reworking these old videos, but it would be a LOT more work... orders of magnitude more work...
Find people from the same region today, ideally descendants of people who were in the video, and deepfake their faces onto the video. Possibly go a step further and find period clothing, and deepfake the clothing in higher resolution onto the video. Or at least get samples of the materials and use that to deepfake improvements to the "resolution" of the video. Could do something similar with the audio.
