Grok Imagine - Cinematic Videos with Synchronized Audio

Does Grok Imagine generate audio as part of the video, or do I need to add sound separately?

Native audio synthesis is built into Grok Imagine, so the tool generates synchronized sound effects and background music in the same pass as the video itself. You do not need post-production audio work; the sound effects naturally sync to visual events in the final output.

Can I use multiple reference images to guide the style of a generated video?

Yes, Grok Imagine accepts up to 7 reference images as input to help match a specific visual style or aesthetic. This is useful if you want to maintain consistency across a series of videos or ground the generation in exact compositional details.

What aspect ratios does Grok Imagine support?

The tool supports 16:9, 9:16, 1:1, 4:3, 3:4, 21:9, and 9:21 aspect ratios. It also includes a Video Reframe tool if you need to convert a generated video from one aspect ratio to another after creation.

How much text can I include in a prompt to describe what I want?

Prompts can be up to 10,000 characters long, which is enough room for detailed descriptions, stylistic direction, and scene-by-scene breakdowns. This length lets you specify nuance that shorter prompts cannot capture.
