Veo 3.1 is Google DeepMind’s video generation model, released in late 2025. It produces 1080p clips of roughly 8 seconds per generation, with synchronized sound, and adds ingredients-to-video and scene extension on top of what Veo 3 did.
What is Veo 3.1?
It is a text-to-video and image-to-video model reachable through the Gemini app, Google Flow and the Vertex AI API. “Ingredients to video” lets you supply up to three reference images โ a character, a prop, a location โ and keep them consistent across shots.
Audio is generated alongside picture, covering dialogue, effects and background music. Google pairs it with SynthID watermarking, so every output carries an invisible provenance mark.
What are Veo 3.1’s main features?
- Native audio: dialogue and sound effects in one generation pass.
- Scene extension: continue a clip past the base 8 seconds.
- Ingredient references: up to three images to lock character and setting.
- 1080p output: with a vertical mode for Shorts and Reels.
- SynthID watermark: invisible provenance on every frame.
Product Highlights
- Scene extension helps, but drift creeps in after two or three continuations.
- Consumer access sits behind Google AI Pro ($19.99/month) or Ultra ($249.99/month).
- Vertex AI bills per second of generated video, which gets expensive for iteration.
What is Veo 3.1 used for?
- Product ads that need a spoken line and sound design.
- Vertical social clips from a single product photo.
- Storyboarding a scene with a consistent character across shots.
- Localizing an existing ad into another language.
- Filling gaps in a timeline with generated b-roll.
Quick Summary
- Veo 3.1 is Google DeepMind’s 2025 video model with native audio.
- Base clips run about 8 seconds at 1080p and can be extended.
- It accepts up to three reference images for consistency.
- Consumer access starts at $19.99/month through Google AI Pro.
- SynthID watermarking is always on, which matters for rights-sensitive work.
