Grok Imagine Video Edit

Edit an existing video with a text instruction using xAI’s Grok Imagine. Provide the public URL of the source clip and describe what should change. The output keeps the source clip’s length.

Model

xai/grok-imagine-video-edit

Pricing

Billed per second of generated video plus a per-second charge for the source video. The per-second tier is decided by the source clip’s resolution, and the output is as long as the source.

Source clip resolution	Per generated second	Per source second
480p	$0.025	$0.005
720p	$0.035	$0.005

Example: editing a 10-second 720p clip costs 10 ×

0.035 + 10 ×

0.005 = $0.40.

Parameters

Parameter	Type	Required	Description
`prompt`	string	Yes	What to change in the clip
`video_url`	string	Yes	Public URL of the source clip to edit
