Video model guide

Veo 3.1 Lite video generation with the length and the tier you pick

Generate from a description or from a starting frame. Set 4, 6 or 8 seconds, choose 720p, 1080p or 4K, and pick a shape in both modes. This page covers the two Lite entries.

Controls and specifications

Veo 3.1 appears in the selector as several separate entries. This page describes the two Lite ones, which are the entries where the clip length and the quality tier are selectable: 4, 6 or 8 seconds at 720p, 1080p or 4K. The shape selector stays available in both modes.

Text to video builds a shot from your description. Image to video takes one picture to define the first frame, or two pictures to define a first and a last frame, and moves between them. Both entries keep a translation switch and an optional watermark text field under Advanced parameters.

Choose 4, 6 or 8 seconds and 720p, 1080p or 4K. Both modes offer 16:9, 9:16 and Auto. Advanced parameters hold a translation switch, which starts on, and an optional watermark text field. Descriptions are capped at 2000 characters, and the image entry accepts one or two pictures.

What this model is good at

Three lengths, three tiers

Choose 4, 6 or 8 seconds and 720p, 1080p or 4K on the same entry. Changing quality creates a new generation; it does not upscale or reproduce an earlier result.

A first and a last frame

Supply one picture to start from, or two to land on. That is how a move between two composed stills stays inside a single task instead of being joined together afterwards in the edit.

A shape in both modes

Both modes offer 16:9, 9:16 or Auto. Choose 9:16 for a vertical target. Auto lets the service choose the ratio and may crop an input image; review the result.

Typical projects

Cut to the length of the slot

A 4-second sting for a feed placement and an 8-second establishing move come from the same entry, so a storyboard with mixed lengths does not need a second product.

Move between two stills

Give the image entry a starting frame and a closing frame and describe the move between them. The result is one clip rather than two that have to be joined.

Weigh a tier against the placement

Render the same description at 720p and at 4K and compare the two on your own footage before you commit a campaign to the higher tier.

Limits to know before you start

  • Generated clips can include audio. Neither entry has a sound on/off switch; review the soundtrack and mute it in your editor when you need silence.
  • This page covers the two Lite entries. Veo 3.1 is also listed as a Fast and a Quality entry that render a fixed 8-second clip at one resolution each, and as a reference entry that takes up to three pictures and runs 8 seconds at 16:9 or 9:16. Those are separate products and are not described row by row here.
  • The image entry accepts two pictures at most: one starting frame, or a starting frame plus a closing frame. There is no third picture and no named subject, product or voice material.
  • Descriptions are capped at 2000 characters. There is no negative prompt field and no seed field, so a run cannot be repeated from a stored seed.
  • Prompt translation starts on and requests English translation before generation. Turn it off to submit your original wording; this does not guarantee literal rendering.

How to start

1

Open the workspace

Use a button on this page. It opens the right workspace with this model already selected, in the language you are reading now.

2

Describe the result

Write what should happen in the shot or image. Concrete subjects, framing and action give the model more to work with than short labels.

3

Set the controls and confirm

Choose length or quality tier, shape and sound where offered, then read the credit quote for those exact settings before you generate.

What it costs

Generation uses account credits. Cost depends on the model, quality and output size or duration. Reference images, video or audio may add charges in some modes. Check the workspace quote for your selected inputs and settings before generating; the pricing page lists credit packages.

Questions about this model

Which Veo 3.1 entries does this page describe?

This page covers Lite text-to-video and Lite image-to-video. Fast, Quality and the separate reference entry have their own controls and are not covered here.

How long can the clip be?

Choose 4, 6 or 8 seconds in either mode. Check the delivered duration before fitting a clip to an exact editing slot.

Can I set the shape of the video?

Both modes offer 16:9, 9:16 or Auto. Auto selects the ratio automatically and can crop an input image. Select an explicit ratio when the placement requires one.

Does it generate sound?

Generated clips can include audio. Neither entry has a sound on/off switch; review the soundtrack and mute it in your editor when you need silence.

How many pictures can I use?

The image entry takes one or two: one starting frame, or a starting frame plus a closing frame. Three pictures belong to the separate reference entry, which this page does not describe.

What does a task cost?

The current quote depends on resolution. At the same resolution, 4, 6 and 8 seconds have the same credit cost. Check the displayed total before generating.
