Steam's new video recording feature is a bit wonky, but it's a start.

So I set up the recording beta on my Steam Deck, and despite some not-quite-there features, it kind of worked?

It only lets you send files if they're under 100mb/60 seconds, and you have to be under both for some features. Fortunately, despite a bug that prevented me from exporting to mp4 I finally got it working. Figuring out how to clip stuff can be kind of hit and miss, especially if you've recorded multiple clips.
