3D Billboard Ad Illusions City Brands

Generate a static 9:16 iPhone-style video of a massive corner building billboard displaying an anamorphic 3D advertisement. A large fictional CGI mascot appears to push out of the flat LED screen through forced-perspective illusion — no camera movement, no cuts, single take. Swap 2 variables to customize: - [CITY] — location & lighting mood - [TYPE OF ADS] — brand or product category Works with Gemini Video. Great for social media mockups, ad concept reels, and creative portfolio.
