MP4 with H.264 / H.265 / AV1 codec, duration 2–15s. Grok Extend Video continues from your source clip’s last frame.
Cost: 6 credits per generation. Choose an extension length between 2–10 seconds (default: 6 seconds).
Grok Extend Video is an AI video continuation workflow built for one specific creative goal: continuing an existing short clip from its last frame. If your source video already has the right look, framing, and motion direction, Grok Extend Video helps you extend the moment instead of starting over with a completely unrelated new video.
The workflow is grounded in three inputs: a compliant MP4 source clip, a prompt describing what should happen next, and an extension duration between 2 and 10 seconds (default: 6 seconds). The continuation is generated as a seamless next segment anchored in the ending of your source video.
Because this is continuation-focused, prompt quality matters. The best prompts describe the next beat clearly—what the subject does, how the camera should behave, and how the environment should evolve—so the generated segment can match your intent while staying visually consistent with the original clip.
Supported formats and compatibility: Grok Extend Video accepts MP4 sources using H.264, H.265, or AV1 codecs. Output resolution options are 480p and 720p. Each generation costs 6 credits.
Feature 1
Grok Extend Video continues an existing short clip from its final frame. That means the extension starts where your source ends, so the continuation can preserve framing, motion intention, and the overall feel of the scene. Instead of rebuilding the moment from scratch, you guide what happens next while the clip’s ending becomes the anchor for the generated segment.
Feature 2
You direct the continuation using a natural language prompt. The most effective prompts describe the next action and how the scene should evolve: what the subject does, what changes in the environment, and how the camera behaves. With a prompt that focuses on a single coherent “next beat,” your Grok Extend Video extension can feel more intentional and easier to iterate on.
Feature 3
Short videos often need a bit more time to land a message. Grok Extend Video helps you extend a clip by adding 2 to 10 seconds (default: 6 seconds) of continuation. This is a practical fit for finishing beats in social content, adding a reveal to a product demo, or shaping landing page visuals so the viewer gets a complete story moment.
Feature 4
Grok Extend Video supports output resolutions of 480p and 720p. Resolution matters because it affects the visual compatibility of the produced continuation. By working within the supported options, you can keep the extension aligned with how your source clip is presented and reviewed.
Feature 5
The Grok Extend Video workflow is intentionally simple: you upload a supported MP4 source clip, write a prompt for the next segment, and generate one extension. The goal is creative continuity—helping you keep what already works and build forward in time rather than starting over from a completely new starting point.
Feature 6
When you extend a clip, pacing becomes a creative control. Grok Extend Video lets you choose an extension length between 2 and 10 seconds, so you can match the continuation to your intended rhythm—whether you need a quick payoff or a fuller follow-through that completes a scene.

Start Extending Your VideoGrok Extend Video performs best when your extension prompt matches the motion and intent of your source clip’s ending. The strongest continuity starts with a final frame that is clear, stable, and compositionally consistent.
Grok Extend Video supports output resolutions of 480p and 720p. Using the supported options helps keep the extension aligned with the quality expectations for short-form clips. If you want consistent presentation, choose an extension length that fits the pacing of your source ending.
Try writing your prompt like this: “Continue the scene from the last frame. The subject [next action]. Camera [behavior]. Lighting and atmosphere [description]. End on a clean, readable final frame for the next moment.”
Grok Extend Video is an AI video continuation workflow. You provide a short, existing MP4 source clip, and then you use a prompt to describe what should happen next. The extension is generated from the clip’s last frame so the result is a continuation of your original moment.
