Overview

Veo 3.1 Fast Text-to-Video turns a written prompt into a short generated video using Google's Veo 3.1 Fast model, with optional native audio and dialogue support. Use it for prompt-only ad concepts, launch visuals, social motion drafts, and storyboard tests when 4-, 6-, or 8-second clips fit the brief.

Use cases

  • Create a short social or ad video concept from a written creative brief.
  • Draft an audio-enabled scene or dialogue moment before moving into production review.
  • Generate 16:9 or 9:16 prompt-only videos for campaign or launch-storyboard exploration.
  • Use negative_prompt to steer away from unwanted artifacts, styles, or scene details.

Input tips

  • Write a prompt that describes subject, setting, action, camera movement, mood, and any dialogue or sound.
  • Keep prompts under 20,000 characters.
  • Choose 4s, 6s, or 8s duration; 8s is the default.
  • Choose 720p, 1080p, or 4k resolution, and 16:9 or 9:16 aspect ratio.
  • Leave generate_audio on when sound or dialogue should be generated; turn it off for silent drafts.
  • Use seed, negative_prompt, safety_tolerance, or auto_fix only when those controls matter.

Expected output

The AI Tool returns one generated video with a downloadable URL and optional content type, file name, file size, and cost metadata. The shared video output view renders the video for playback, review, and download; duration is requested input, not returned as output metadata.

Caveats

  • This text-to-video AI Tool does not use source images, end frames, or reference images.
  • Generated motion, audio, dialogue, people, products, and text should be reviewed before use.
  • Duration is requested input and is not returned as video metadata.
  • auto_fix may rewrite the prompt; review the final video against your original intent.
  • Safety settings and model policy can block, alter, or constrain some prompts.
