It's nice to see, but just some initial fooling around leaves more to be desired. There's basic ease of use things that other recording systems have had for years that it seems to lack. Such as a quick and easy way to just say "save the last x minutes."
No, you can either record far more than necessary and drop pins for later, or you can specify when to start and stop (as if you know when somethings coming up), or apparently grab only the last 10 seconds in a quick clip.
I prefer to save recent funny things, but sometimes they are varying time lengths. So it's a tad disappointing, but it's pretty cool for a start.
Also it's already crashed my Steam Deck once within like 10 minutes of fooling around with it.
