How do you keep a "swipe file" of social videos worth learning from?

Something I've never solved well: keeping a reference library of video posts that actually taught me something — a hook that worked, an ad structure, a demo that landed.

Screenshots kill the motion, which is half the point of a video. Bookmarks on X work until you've saved 300 things and can never find the one you want. And browser tabs are not a system.

The closest I've gotten is pulling the raw video file down and dropping it into a dated folder with a one-line note on why I saved it. Low-tech, but it's the only version that's survived more than a month. The annoying part was always the download step — most of the "save tweet video" sites are wall-to-wall fake buttons and redirects, and a lot of them re-compress the clip or stamp a watermark on it.

I ended up writing up the clean approach I settled on (paste the URL, get the file back at full resolution, no account)

But the storage side is still unsolved for me. How do you keep the videos you want to study — and actually find them again later?
