Gemini + Veo: A Deep Dive into Google’s High-Fidelity Video Generation Pipeline

Google's Veo uses a Latent Diffusion Model architecture optimized for spatio-temporal consistency to generate high-fidelity 1080p video, treating video as a 3D volume rather than 2D frames. Gemini acts as a semantic bridge by performing prompt expansion into detailed cinematographic instructions before conditioning Veo. Key architectural innovations include alternating spatial-temporal transformer attention, a high-resolution VAE preserving fine-grained details, and integration through the Vertex AI ecosystem.
