This is an animated crowd dancing. It is low poly and the textures are very stupid. So this can only be used for stuff in the background or in the dark. Definitely does not work for close-ups. There's a male and a female character in this, both have AI generated faces. so do not worry about the identity of these people, they don't exist.

The only files that contain animation are the FBX and Alembic (.abc)

Use the Alembic, it is better.
