Where can I find this video?

I think you are wrong because links you shared aren't a good proof.
One your first link: https://smutty.com/s/UBBIX/ the watermark isn't enought to proof her name. More, this watermark Snaptchat: katiewillsx2 appears on many other pics of different girls:

and more....

Then, there is a IG profile with this name but it's empty: https://www.instagram.com/katiewillsx2/
Here, the PimpEye results with the profile pic:

And some links with many other photos of this same girl:

You can see that the OP's source photo never appears...

Now if you compare the OP's source photo with this girl's photo on IG, you can see some differences between their bodies like moles or tattoo:

In red circles, some moles on her boobs and belly. And there is nothing in green circles. Check the tatoo too that not appears on the OP's source.

There is no more pics of the girl in the OP's source. So, I really think she is just a single pic of an unknowned amateur on the beach....

Her name is Katiewillx2 on Snapchat.
