Keep the camera rolling.

Point veo3-1-fast-extend or veo3-1-quality-extend at a finished take and write what happens next. Veo picks up from the last frame at second eight, so camera, light and characters carry straight through the cut.

    Shoot the source

    Generate with veo3-1-fast or veo3-1-quality as usual and keep the returned task_id.

  2. 02

    Submit the extension

    Switch to the matching extend model, pass the task_id as remix_task_id and describe what comes next.

  3. 03

    Collect the cut

    Poll the new task for the 15-second video, or set raw to true to receive only the new segment.

Editor's notes

  1. Same family only: the fast line (including 4K and ref) uses veo3-1-fast-extend, the quality line uses veo3-1-quality-extend. Lite is not supported yet.
  2. The source must be a completed task from your own account, created within the last 48 hours.
  3. An extended video can't be extended again; each source tops out at 15 seconds.
  4. The aspect ratio follows the source unless you set 16:9 or 9:16. Resolution can be 720p, 1080p or 4K.
  5. Extension works from the source alone: no new images, video or audio, and no duration to set.

Waveform measured from this clip's actual audio track

Pictures that bring their own sound.

Veo 3.1 generates audio alongside the picture: a fingertip scratching across paper, the wet slap of tentacles on wood, every sound locked to its frame with nothing to dub afterwards.

Foley
Actions and materials sound the way they look.
Sync & rhythm
Dialogue, footsteps and cuts stay in time.
Ambience
Rain, crowds and city hum follow the scene.

From one sentence to a set of references.

One endpoint, three starting points. The number of images decides what they mean, so there's no extra mode flag.

Just a prompt: framing, camera moves and mood all come from your words.

First / last frame

The first image opens the shot, the second closes it, Veo fills the motion in between.

Multi-reference

One reference each for character, style and set, so the same face holds across shots.

FAQQ & A06 / 07

Questions, answered

What is Extend?

Extend continues a finished Veo 3.1 video, taking an 8-second source to 15 seconds. Call veo3-1-fast-extend or veo3-1-quality-extend and pass the source video's task_id as remix_task_id.

Which videos can be extended?

The source must be a completed, regular Veo 3.1 generation from your own account, created within the last 48 hours. The fast line (fast, fast-4k, fast-ref) uses veo3-1-fast-extend and the quality line (quality, quality-4k) uses veo3-1-quality-extend. Lite videos and already-extended videos can't be extended yet.

What does the raw parameter do?

By default raw=false returns the full 15-second video, source plus extension. Set it to true to receive only the newly generated segment, handy when you stitch clips in your own editing pipeline.

Which aspect ratios and resolutions are supported?

16:9 landscape and 9:16 portrait, at 720p, 1080p or 4K (or use the -4k models for fixed 4K output). Extensions keep the source's aspect ratio unless you set one.

Does every video include sound?

Yes. Veo 3.1 natively generates sound effects, ambience and dialogue in sync with the picture, and the MP4 ships with its audio track.

How do I choose between Quality, Fast and Lite?

Quality delivers the best image for final output, Fast balances speed and cost for most work, and Lite is the cheapest way to explore ideas in bulk. Live prices for every tier are in the model list above.

How many reference images can I upload?

Fast and Quality take up to 2 images, used as the first and last frame. veo3-1-fast-ref takes up to 3 images as character, style or scene references.

Can I use the generated content commercially?

Content generated via the API is owned by the account holder and may be used commercially. See the Terms of Service for details.
