What is Grok Imagine 1.0 Video Edit?
Grok Imagine 1.0 Video Edit runs xAI's classic 1.0-class video model on a video you already have and changes it according to a text instruction. Pass the public URL of the clip and a prompt describing the change, and xAI's Grok Imagine returns a new clip of the same length and aspect ratio with the edit applied: a different time of day, weather, palette, wardrobe, or scene dressing, while the action and camera stay as they were.
The model key is xai/grok-imagine-1.0-video-edit. It works on any public clip up to 8.7 seconds, not only Grok output, and renders at up to 720p.
Key features of Grok Imagine 1.0 Video Edit
Prompt-driven video-to-video
Describe the change in plain language. Relighting, weather, season, color grade, and object swaps are the typical edits; the motion and framing of the source are preserved.
Any source clip by URL
The input is a URL, so clips from Grok Imagine 1.5 Video, 1.5 Lite Video, another model, or a camera all work. Upload a file in the playground and it is hosted for you.
Length and ratio follow the source
There is nothing to configure: the output matches the source clip second for second and keeps its aspect ratio, capped at 720p.
Two fields, no surprises
Only video_url and prompt are accepted. Unknown fields are rejected up front, so a typo cannot quietly change a billed job.
Chains with Extend
Edit first, then continue the result with Grok Imagine 1.0 Video Extend for a longer sequence in the new look.
What Grok Imagine 1.0 Video Edit is best for
Relighting and weather
Turn a daytime take into night, add rain or snow, or shift golden hour to overcast without a reshoot.
Look variants of one shot
Produce several color grades or styles from one approved clip to compare in an edit.
Fixing generated clips
Change the detail you did not like in a Grok Imagine 1.5 Video output instead of regenerating the whole thing.
Scene dressing
Swap props, signage, or background elements described in the prompt while the subject keeps moving as before.
Grok Imagine 1.0 Video Edit limitations
Source clips must be publicly reachable and at most 8.7 seconds long; longer sources are rejected. Output is capped at 720p and always matches the source length and ratio, so this is not the route for reframing or extending (use Grok Imagine 1.0 Video Extend to add seconds). Edits that need new camera moves or a different subject are better served by regenerating on Grok Imagine 1.5 Video with the source as a start frame.

FAQ
Grok Imagine 1.0 Video Edit에 대해 자주 묻는 질문
It rewrites an existing video according to a text instruction. Give it the public URL of a clip and describe the change, for example "make it night with rain and neon reflections", and it returns a new clip of the same length and aspect ratio with the change applied.
Any clip reachable at a public URL, up to 8.7 seconds long, from any source. It is not limited to videos generated by Grok. The output is capped at 720p.
Two. video_url, the public URL of the source clip, and prompt, what should change. There is no duration, aspect ratio, or resolution field; the output follows the source, and unknown fields are rejected before any charge.
Per generated second at a rate decided by the source clip's resolution (a 480p tier and a 720p tier), plus a small per-second charge for the source video. Because the output is as long as the source, a 6-second clip is billed as 6 generated seconds plus 6 source seconds.
Yes. Each edit returns a new video URL, which you can pass back as video_url for a further change, or hand to Grok Imagine 1.0 Video Extend to continue it.
Because xAI runs its video edit endpoint on the classic Grok Imagine video model, the 1.0 generation, whichever model made the source clip. The name says which engine renders the edit, and it is why the output is capped at 720p. An earlier web-based edit key was removed in July 2026; this is a new model on xAI's API.
