When I was young and lived in the country with a big pond and marshland, most of the frogs went “THUMMM” at night (like this https://m.youtube.com/watch?v=6qHBRXLHXnc) and the others were more like a high pitch creaky door or one of those hollow wooden frogs with the back ridges that you play with a stick, like this

I’ve never lived near any sort of frogs that I’d describe as making a riib sound
I think this is the sound you are talking about?
It’s kinda harder to pick out in your video for me, but there’s a distinct riib sound there over the top of everything else that’s absent from the other video. If that’s not the sound you are talking about, I’m pretty sure it is the source of “ribbit”.

Have you ever set by a creek on a warm summer night? It’s more like riib riib riib riib, but I can see where ribbit came from
Edit: found this which is pretty close to what I’m talking about.
