Oh my... y'all need to chill.
Download yt-dlp and run this command, to get CNN's 'direct' 245MB stream on your hard drive instead of AP's (or YouTube's) tiny re-encodes on a web player:
yt-dlp -f direct https://www.cnn.com/2025/09/10/us/video/trump-oval-office-statement-white-house-charlie-kirk-death-digvid

See that combing? It's interlaced.

Or telecined, I think, to be more specific. While it's impossible to know what the actual feed from the White House looked like, re-encodes I'm looking at are clearly de-interlaced (poorly) which is why motion looks so weird. It's also choppy and MPEG-blocky, hallmarks of poor encoding even in a 13.9 Mb/s stream, and recompressing that to a tiny bitrate makes it even worse.
Y'all (and apparently the rest of the internet) are obsessing over literally decades-old video encoding/broadcasting issues and oldschool video filters to fix them that have nothing to with AI.
