Uh, I am tad bit confused by what you said so let's answer everything you asked?
Is the new feature supposed to save recordings locally or somehow tell twitch to start recording the broadcast?
**Open OBS/click settings/click Hotkeys. Bind recording to any key you want.**
I can't seem to find where the recording ends up.
**The local recording should end up in your videos folder unless you changed the file path? Open OBS/Click File at the top left/ and select Open Recording Folder.
Did that answer your question or was it involving something else?
