Grok Video Editing Suite: Edit & Extend
Last updated: May 4, 2026
Two models, one complete video editing pipeline. Grok Edit Video transforms what's already there. Grok Extend Video adds what comes next. Together, they give creators full control over video content from within Scenario - no timeline software, no VFX suite required.
Introduction
Grok Edit Video and Grok Extend Video are xAI-powered video tools integrated into Scenario, built around a simple principle: describe what you want in plain language, and the model handles the rest. Both tools are part of the Grok Imagine family - xAI's visual generation engine - and bring the same semantic intelligence that powers the Grok language model into the domain of video production.
Grok Edit Video is a video transformation tool. Give it a clip and an instruction - "make the car metallic silver," "add giant scorpions emerging from the sand," "retexture the robot in gold and chrome" - and it reinterprets the footage according to your prompt while preserving the original composition, motion, and timing.
Grok Extend Video is a video continuation tool. It picks up where your clip ends and generates new footage that flows naturally from the last frame. You describe only what should happen next - the model reads the visual context of the source and produces a coherent continuation.
Parameters and Settings
Grok Edit Video
Prompt (Required): Natural language instructions describing the desired edit. Be specific about what to change and what to keep.
Example: "Change the environment to a snowy mountain pass, keep the subject and motion unchanged."
Source Video (Required): The video to edit. Auto-preprocessed to a maximum of 8.7 seconds at 720p. Longer or higher-resolution clips are automatically trimmed and resized.
Grok Extend Video
Prompt (Required): Describe only what should happen in the new footage (the continuation). Do not re-describe the existing clip.
Example: "The camera pulls back to reveal the full room, light shifting from white to warm gold."
Input Video (Required): The source video to extend. Preprocessed to a maximum of 15 seconds at 720p.
Extension Duration: Controls how many seconds of new footage to generate. Range: 2 to 10 seconds (Default: 6 seconds).
Prompt Craft
For Grok Edit Video: Write instructions as directives: "Make," "Change," "Add," "Remove," "Retexture," "Replace." Specify what to preserve as well as what to change to prevent unwanted alterations.
For Grok Extend Video: Write the continuation as a description of what the camera sees or what happens next. Think like a cinematographer or director giving a brief for the next shot.
What to avoid: Vague instructions ("make it better"), contradictory directives, and overly long prompts. Clear, specific, single-direction prompts consistently perform best.
Use Cases
Grok Edit Video is built for:
Product visualization: Retexture, recolor, and restyle physical products without reshoots.
Character and environment transformation: Change a person's look or apply visual style shifts across a clip.
Creative VFX: Add fantastical elements like creatures or weather effects directly into footage.
Rapid iteration: Test multiple visual treatments of the same scene in minutes.
Grok Extend Video is built for:
Narrative extension: Add a story beat, reaction, or reveal to the end of a scene.
Product reveal pacing: Control how long a showcase lingers after the initial reveal.
Scene building: Combine multiple extensions to build longer sequences.
Content repurposing: Extend short clips to meet minimum duration requirements.
Conclusion
Grok Edit Video and Grok Extend Video bring the intelligence of xAI's Grok directly into Scenario's video workflow, removing the barrier between creative intention and finished footage. Used together, they create a powerful iterative loop: source a clip, transform it with Edit to match your visual direction, then lengthen it with Extend to build the full scene you need.
Both models are available now in Scenario. Start with a clear instruction, observe how the model interprets your prompt, and refine from there.
