It’s a 1.6 GB video and every smart phone and PC has a built in unzipper.
There’s no reason to not download the zipped one, even if your technologically impaired it’s literally a single button press on both iPhone and Android and two clicks on a PC.
And if you’re worried that a zipped file might have something malicious, take a Xanax. It’s been downloaded way over 1,000 times, someone would have complained by now if there was anything wrong.
