Spring Peepers make a "Peep...Peep...Peep" noise.

I'm on bandwidth limited internet so I haven't watched the video, but if you can figure out where the part with the trilling was recorded, you can head to AmphibiaWeb: World Map Search and narrow it down to the area. They have many sound recordings available when you get down to the province/state level lists of local amphibians. Any with missing sounds can be searched for individually on google, or by area (e.g. "frog calls of Ontario" coughs this up: https://www.naturewatch.ca/english/f...ml?Province=on)

I'll take a bold stab at a 'high pitched trilling" and suggest American Toad (though there's little or no overlap with Pseudacris regilla's range).
