How to Make an AI Video With Sound Using Veo 3.1

Updated 22 July 2026 · 4 min read

Most AI video tools give you silent clips you then have to score yourself. Google Veo 3.1 is different: it generates the video and matching audio together — dialogue, ambient sound and effects — so your clip feels finished the moment it's done. Here's how to use it inside Mina Labs.

Why Veo 3.1

• Native audio. Sound is generated in sync with the visuals, not bolted on after.
• Up to 4K. Choose 720p, 1080p or 4K depending on where the clip will be used.
• Cinematic quality. Veo handles lighting, camera movement and realism especially well.

Step-by-step

1. Open Veo 3.1. Go to the Veo 3.1 generator in the Video Studio.
2. Write a prompt with sound cues. Describe the scene and what you should hear — e.g., "a chef sears a steak in a busy kitchen, sizzling and clatter in the background, he says 'perfect'." Veo will generate the matching audio.
3. Choose duration and resolution. Veo supports 5, 8 and 10-second clips at 720p, 1080p or 4K. The price updates to match your choices before you generate.
4. Keep audio on. Make sure "generate audio" is enabled.
5. Generate and save. It runs in the background; when it's ready, preview it with sound and save.

Prompt tips

• Name the sounds you want. Dialogue in quotes, plus ambient cues ("rain on a window," "distant traffic").
• One location, one moment. Short, focused scenes look and sound the most convincing.
• Add a camera direction. "Slow dolly in," "handheld," or "static wide" changes the whole feel.
