Do not pay for it. There is so many restrictions. When you think you got something cool going and use a bunch of credits then get ready to animate it. It tells you it's against there guidelines. So you back track to find out what it is that's against the guidelines and by that time you already used all your credits, scenes change. Its complicated, and very frustrating to use.

The app is good while it works, but once it gets a bug, it completely stops doing any task and there is no one who can help with it. I continuing get a "Generation Failed" block with the most innocent images such as trying to change the color of my characters dress as she hangs up a Christmas stocking. adding a collar to an image of a rabbit, etc. If the most innocent of images trips their safety filters, what good is it?

Extremely heavy handed and onerous guardrails, in no small part because they're full of false positives. To the extent that trying to use the app's own "animate image" feature on an image generated *in the app* of an original character, an alien with features so exotic AIs struggle to generate her correctly is misidentified as 'a prominent person.' The models and prompt adherence are good, but it's completely crippled by the fact that they're trying to control what you can and can't do with it.
