What is Veo 3.1 Reference-to-Video?
Veo 3.1 Reference-to-Video is Google DeepMind's reference-guided video generation model that creates video while maintaining visual consistency with provided reference images. The model preserves subject identity, visual style, and compositional characteristics from the reference throughout the generated video. With per-second billing at $0.20 per second base, the model supports both 1080p and 4K output with optional audio generation. 4K and audio each double the base cost. Up to 8 seconds of video can be generated per request. The reference guidance ensures consistent character appearance and visual style. Compared to standard text-to-video models that rely solely on prompts for visual direction, reference-guided generation provides significantly tighter control over the output's visual identity. Against Kling's reference-to-video options, Veo 3.1 brings Google's premium video quality and flexible resolution options. Best suited for character-consistent video from reference images, brand content, and product demonstrations where maintaining visual consistency with reference material is essential. Available on FairStack at infrastructure cost plus a 20% platform fee.
