KATU, this local news site, are the ones who not only produced the original segment, but 50 years later, worked with the historical society to restore and digitally remaster the original film. Their article contains context and retrospective commentary.
edit: to be clear, just explaining why I submitted the link rather than the Youtube link. I don't endorse dark patterned ad code, though I've tried opening the link in a couple of incognito browsers and didn't run into any issues.
Looks like I ended up being in the wrong then. This morning when I read it, the article embedded the high-res Youtube video (which you could also click to view directly on Youtube) at the bottom of the article. Looks like that at some point today, they've removed the Youtube embed for their own player:
The remastered 'chunky text' is a bit jarring and incongruent on the 4k version. It's just too sharp to be placed on film stock with that much grain. And then there's the issue of ruining the footage with these burned-in overlays (countdown, really?)
