Where can I find this video?

Complicated answer. There is no video. It's just a modular 3D render with multiple creators.
The body "Victoria 4" is made by Daz
The model/texture called "Danielle" is rendered by Addy
The hair "Immortal Dream Hair" is made by Magix 101
The outfit "Sexy Ruffles" is rendered by Supernova
The hub for selling these assets Renderosity.

Here are some more photos of the model:
