Q1: How does Google Veo 3.1 Ingredients to Video keep characters consistent?

A: Unlike standard text-to-video prompts that reinvent faces, Google Veo 3.1 Ingredients to Video lets you upload up to 3 distinct reference images—typically assigning Image 1 to your character/subject, Image 2 to an interactive object or prop, and Image 3 to the scene background. By referencing each image's role in your prompt, you eliminate identity drift across episodic scenes.

Q2: How do I use First and Last Frame control in Google Veo 3.1?

A: Upload a starting keyframe image and an ending keyframe image, then describe the camera movement or transformation in between. Veo 3.1's frame interpolation engine bridges the two states with smooth physics and lighting continuity.

Q3: Can Veo 3.1 generate native 9:16 vertical videos for TikTok and YouTube Shorts?

A: Yes. Veo 3.1 supports true native 9:16 vertical video generation alongside 16:9 widescreen, ensuring mobile-first framing for TikTok, Instagram Reels, and YouTube Shorts without cropping or resolution loss.

Q4: How do I prompt for spoken dialogue and sound effects (SFX) in Veo 3.1?

A: Simply enclose spoken lines in quotation marks (e.g., She says, "We need to go now.") and clearly state sound effects or ambient noise (e.g., SFX: distant thunder; Ambient noise: quiet cafe murmur). Veo 3.1 generates synchronized lip movement and audio in the same pass.
