Flaws in image/video encryption via pixel shuffle vs AES encryption

I've come across a site that boasts they are an "Unrivalled" media encryption service. While it is hard to find exactly what they do differently, it appears they use AES encryption to encrypt media files, which can then be directly downloaded as a .crypt file onto a device. This effectively renders the downloaded file useless, with no way of getting access. Is this correct? If not, what flaws could compromise it's security?

However, I also see the more common online tools that scramble image pixels using the run of prime numbers and a pseudorandom generator.

But which one is safer, and presents the least flaws? Why go through the effort to perform shuffle on pixels, while you can instead encrypt the entire file using AES?

The website looks like a way for whoever controls the domain to gather a collection of images and media clips. Almost any article that illustrates how well it's image file encryption works using a visual (often of [Lenna](https://en.wikipedia.org/wiki/Lenna)) is to be regarded as seriously as a math article using an example as proof.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
