This is a new My Little Pony movie where the ponies are made humanoid after walking through some stargate like contraption. I say humanoid rather than human, because they still retain their brightly colored skin and hair, something that is not natural for people, but appears to be the natural colors of the MLP ponies, in both pony and humanoid form.
Here's some official artwork for this movie.
And here's the trailer.
