How AI Video Extension Works

Start with an existing clip, describe what happens next, and generate a continuation that follows your original scene.

  1. 01

    Start with Your Video

    Upload the clip you want to continue. Choose a source video with a clear ending and enough visual context for the next moment.

  2. 02

    Describe What Happens Next

    Explain the next action, how the scene should develop, and whether the camera should remain still or continue moving.

  3. 03

    Generate the Continuation

    Review the generated segment and check how its movement, setting, and visual details relate to the source clip.

Prompt Tips

Describe the next moment clearly, build on the existing action, and guide how the scene continues.

01

Describe What Happens Next

Write the next action as a clear continuation of the source clip. Instead of restating the whole scene, describe what the subject does next and how the action develops.

Hallway Source → Kitchen Continuation

Prompt idea · Not yet tested

Continue directly from the final frame of the source video. The woman reaches for the door handle, turns it, and pushes the door open. She steps into a warmly lit kitchen, walks to the counter, places her keys beside a bowl of fruit, then picks up a glass and pours herself some water. She takes a sip while looking out through the kitchen window. Use continuous, natural movements as the action progresses from the hallway into the kitchen. Keep her appearance and outfit consistent with the source video.
02

Keep the Scene Connected

Refer to the existing environment, lighting, and character appearance when they matter to continuity. Avoid introducing unnecessary changes that make the continuation feel like an unrelated scene.

Apartment Source → Hallway Continuation

Prompt idea · Not yet tested

Continue from the final moment of the source video. The woman turns away from the apartment window, crosses the living room, and picks up her handbag from the sofa. She walks to the front door, opens it, steps into the hallway, and pulls the door closed behind her. She then walks toward the elevator and presses the call button, shifting her weight as she waits for it to arrive. Follow her movement naturally from the living room into the hallway, preserving her recognizable appearance, outfit, and the established visual style.
03

Guide the Next Camera Move

If the camera movement matters, explain how it should continue from the original framing. Keep the direction simple and consistent with the source shot.

Hallway Source → Rooftop Continuation

Prompt idea · Not yet tested

Continue the source video as the man walks toward the glass door at the end of the hallway. The camera tracks smoothly behind him as he reaches the door, pushes it open, and steps onto a rooftop terrace overlooking the city at night. Once he reaches the railing, he stops, places both hands on it, and looks out over the illuminated skyline. As he stops, the camera gradually moves from behind him to a three-quarter side view, revealing the city lights in the background. Make the transition from the indoor hallway to the outdoor terrace feel continuous, with natural walking and door-opening movements.

Frequently Asked Questions

What is an AI Video Extender?

An AI video extender uses an existing video as the starting point and generates additional footage based on your prompt. It helps you continue an action, develop a scene, or add the next moment to a video.

How do I write a good video extension prompt?

Describe what should happen after the source video ends. Specify the next action, how the scene develops, and whether the camera should continue moving or change position. Mention important visual details that should remain consistent.

Can I keep the same character and environment?

You can describe the character, outfit, setting, lighting, and camera perspective you want to preserve. Continuity can vary between generations, so review the output to see whether it matches the source video.

Can I extend any video?

Supported formats, file sizes, clip duration, and other input requirements depend on the selected model. Check the requirements displayed in the upload panel before submitting a source video.

What is the difference between Video Extender and Video Editing?

Video Extender generates footage that continues beyond the source clip. Video Editing changes elements within existing footage, such as the background, appearance, or visual style, depending on the supported editing features.
