Overview

Veo 3.1 Fast First-Last-Frame-to-Video turns a starting image, ending image, and motion prompt into a short generated video using Google's Veo 3.1 Fast model, with optional native audio. Use it when a product reveal, before-and-after, or campaign moment needs clear start and end visuals.

Use cases

  • Create a product reveal that starts on one image and lands on a specific final frame.
  • Draft a before-and-after social video from two campaign visuals.
  • Test a fast frame-guided transition with or without generated audio.
  • Compare duration, resolution, aspect ratio, and prompt variants from the same two frames.

Input tips

  • Provide public first_frame_image_url and last_frame_image_url values that can be fetched without login.
  • Write a prompt that explains the transition, camera movement, action, mood, and any audio needs.
  • Keep prompts under 2,500 characters.
  • Choose 4s, 6s, or 8s duration; 720p or 1080p resolution; and auto, 16:9, or 9:16 aspect ratio.
  • Leave generate_audio on for native audio; use auto_fix only when prompt repair is acceptable.

Expected output

The AI Tool returns one generated video file with a downloadable URL and optional content type, file name, file size, width, and height when available, plus 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

  • Both frame image URLs must be public and reachable.
  • First and last frames guide the transition but do not guarantee exact timing, framing, or motion.
  • This AI Tool does not expose seed, negative-prompt, safety-tolerance, or reference-image-set controls.
  • Generated motion, audio, people, products, brand marks, and text should be reviewed before use.
  • auto_fix may rewrite the prompt; review the result against your original intent.
  • Use image-to-video AI Tools when only a starting source image is needed.
