AI Video Extension Tool

Make any video clip longer. The AI picks up from the last frame and continues the scene naturally — same characters, same style, same motion direction.

Extend Any Video Clip Seamlessly

Upload a short video clip and our AI extends it. The extension engine analyzes the final frames and generates new footage that continues the scene without visible cuts. Got a 5-second clip that needs to be 15 seconds? The tool can add new frames that continue the action, the camera movement, and the overall feel of the original footage. It works on AI-generated clips and real footage alike. The transition between original and extended footage is smooth enough that most viewers will not notice where the original ends.

Guide the Extension with Prompts

Optionally write a prompt to tell the extension tool what should happen next. Without a prompt, it continues the existing motion. With one, you can change the scene direction. Say you have a clip of someone walking down a street. Without a prompt, the extension continues the walk. Add a prompt like "the person stops and looks up at the sky" and the AI changes the action mid-clip. This makes video extension useful not just for lengthening clips but for building multi-shot sequences from a single starting point.

Capabilities

Why Use Our Video Extension Tool?

Most AI video generators give you a fixed-length clip and that is it. Video extension lets you keep going, building longer sequences from any starting clip.

Seamless Continuation

The extension AI matches colors, lighting, and motion from the source clip. No jarring transitions between original and new footage.

Prompt-Guided Direction

Add a prompt to steer what happens next, or let the AI decide based on the existing motion in the clip.

Works on Any Source

Extend AI-generated clips, screen recordings, phone videos, or professional footage. The tool adapts to whatever you feed it.

Chain Multiple Extensions

Extend a clip, then extend the result again. Build sequences of 30+ seconds from a single short clip.

1080p HD Support

Video extension output matches the resolution of your input, up to 1080p HD.

Free Credits to Start

Test video extension with free credits on signup. See how well it continues your clips before purchasing more.
