Preview model guide

Grok Imagine Video 1.5 Preview short clips from one second up

A preview video model that renders clips from 1 to 15 seconds in three quality tiers, from a description or one starting image.

Controls and specifications

Preview status means the model is live in the workspace but its behaviour can change between releases. Length, quality tier and shape are the controls you get today.

This workspace offers no sound on/off switch for the model. In the output samples we have checked, finished files carried a sound track, so decide in the edit whether to keep or mute it.

What this model is good at

From one second up

Render a single second to check how a description moves, then repeat it at full length within the same 1 to 15 second range.

Automatic shape

Leave the shape on auto to let the model decide, or pick an explicit ratio in either mode.

Three quality tiers

480p, 720p and 1080p, selectable per task with lengths from 1 to 15 seconds.

Typical projects

Voice-over b-roll

Place the clip under narration and mute its generated track in the edit so the two do not compete.

Quick motion studies

One-second renders to explore how a description moves before a longer version.

Image-driven motion

Animate a still while keeping explicit control of the output shape.

Limits to know before you start

  • No audio switch: this workspace offers no sound on/off control for this model. Output samples we have checked carried a sound track, so mute it in your edit if the placement needs silence.
  • Preview status: behaviour and availability can change between releases.
  • The prompt limit is 4096 characters, lower than the other video models on this page.

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.
