When to reach for it
A prompt alone will not produce a clip here. The model requires a starting image, which makes it an animator rather than a generator. That is a real constraint to plan around, and also the source of its main strength: because the first frame is yours, the look of the clip is settled before the model does anything.
It always generates audio; there is no silent mode. Treat that as part of the output rather than a feature you can decline, and say what you do *not* want in the prompt if the model's instinct for scoring a scene is getting in the way.
Seven aspect ratios, the widest set of any clip model here apart from Seedance, and takes from one to fifteen seconds, which is unusually flexible at the short end. One second is a genuinely useful length for a punctuating cut. No reference images beyond the required starting frame, so it cannot hold a character across shots; pair it with an image model that can, and feed it the frames.

Guides that cover it
- Two pictures, fifteen seconds: the first-and-last-frame method
Make the opening frame and the closing frame yourself, hand a video model both, and let it fill the middle. Nine models take a last frame. What it buys.
- Grok Imagine Video 1.5: the complete prompting guide
One picture in, up to fifteen seconds out, with sound you cannot turn off. Nine rules, three pipelines and the failures worth knowing about first.
