Is there some kind of specific popular site / app on mobile going around that allows people to import art and have it generate an AI animated version??

This is mostly asking a general question. I came here to see if anyone could answer because a person I met not too long ago on Instagram had posted this really smooth animated picture of an anime character’s head turning. There were some give aways of it being AI, like features shrinking for one frame or features gaining extra sides or warping into something else subtly.

Usually I’d just move on, block and ignore people using these generators as I personally dislike the use of them, but this person claims to have created it using VideoStar and CapCut, and claimed it was animated “frame by frame”. I’m not an incredibly seasoned animator but I’m not so sure you can create clean frame by frame drawn animations on either of those apps(?) The other problem is that the art is not drawn by them, so I don’t understand how they could have drawn it frame by frame if they did not even draw the beginning image in the first place. After saying these things they deleted the post and everything related to it after, then moved on like nothing happened. I think it might be obvious by this point that they’re lying to me, but I just wanted to see if there was something out there that’s popular, on mobile and capable of animating anime art. Thank you.

Just a quick disclaimer I will not be posting the video I’m talking about due to my own safety. I’m already pretty nervous even asking about this here. If I get some answers I’ll probably delete this post eventually as well.
