AI Video Extender
Extend any video beyond its original length with AI. Continue a 5-second clip into 15 seconds, extend a scene, or add new content that seamlessly matches the existing footage. The AI maintains visual consistency, motion flow, and style.

How to extend videos with AI
Drop your clip
Upload any video, or right click any video from the AI Video Generator and select "Extend video" to send it here instantly.
Guide the extension
Optionally describe what happens next. "Camera pulls back," "she turns around," or leave it blank and let the AI continue naturally.
Get extra seconds
The AI generates new frames that seamlessly continue your clip. No visible cuts, no style shifts. Extend again to keep going.
Right click any video in the AI Video Generator to extend it instantly.
Best results
Make short clips feel like finished shots
AI video extension works best when the last frames give the model clean visual context. Use it to add breathing room, finish motion, or create a natural transition without looping the same frames.
Read the full AI video extension guideStart from a stable ending
Clips with readable motion, steady lighting, and a clear subject extend more smoothly than hard cuts or heavy motion blur.
Choose the right direction
Extend forward to continue an action, backward to create a lead-in, or both directions when the original clip needs more setup and payoff.
Prompt the next beat
Short prompts like "camera slowly pushes in" or "the character turns toward the window" help steer the generated continuation.
Chain for longer scenes
Generate a few extra seconds, review the result, then extend again. Iterating keeps continuity stronger than asking for one long jump.
What makes this AI video extender different
Most video tools only generate new clips. Melies extends existing clips — continuing the exact motion, style, and content seamlessly.
Seamless Continuation
Extensions match the original perfectly — same style, motion flow, lighting, and visual quality. No visible cut between original and extension.
Motion Consistency
Camera movement and subject motion continue naturally. Zoom, pan, and character motion flow seamlessly into the extended portion.
Prompt-Guided Extension
Describe how the video should continue. 'Camera pulls back,' 'character walks forward,' or 'scene transitions to sunset.'
Chain Extensions
Extend multiple times. Start with 5 seconds, extend to 10, then 15. Build longer sequences from short clips.
Multiple AI Models
Access different video AI models for extension. Try Kling, Runway, or Minimax and pick the best continuation.
Timeline Integration
Extended videos integrate with your Melies timeline. Build scenes by extending, chaining, and composing AI-generated clips.
AI video extender vs loops, slow motion, and new clips
Extending video is different from stretching footage. It creates new frames that continue the shot, giving editors more usable material.
| Method | Best for | What changes |
|---|---|---|
| AI video extender | Adding real extra seconds to the beginning or end of an existing clip. | Generates new motion and visual content that follows the original shot. |
| Video loop | Background ambience, screensavers, or repeatable texture footage. | Repeats the same frames, which can look obvious when subjects or cameras move. |
| Slow motion | Sports moments, dramatic pauses, and shots already captured at high frame rate. | Stretches existing frames rather than adding new action or composition. |
| New AI video | Starting a fresh shot from text or image when continuity with source footage is not required. | Creates a separate clip that may not match the exact lighting, subject, or camera motion. |
AI video extension prompt examples
Use short, practical prompts. Describe the next action, camera movement, or mood shift instead of rewriting the entire scene.
Cinematic reveal
Continue the shot as the camera slowly pulls back, revealing the full city skyline while keeping the same blue-hour lighting.
Character motion
The character finishes turning toward the door, pauses for a beat, and the warm hallway light spills across their face.
Product shot
Extend the close-up with a slow clockwise camera move, keeping the product centered and leaving clean space for a logo.
Nature and B-roll
Let the wave continue rolling toward the beach, preserving the same handheld camera motion and soft sunset color.
What can you extend with AI?
From short AI clips to film scenes, video extension adds length and content to any video.
AI Clip Extension
Extend AI-generated clips from 5 to 15+ seconds. Turn short generations into usable scene lengths.
Scene Building
Build longer scenes by chaining extensions. Start with a shot, extend the motion, and compose a complete sequence.
B-Roll Creation
Extend short B-roll clips into usable lengths. More footage from less source material.
Slow Reveals
Create slow reveal shots — extend a zoom or pan to build tension and visual interest.
Loop Creation
Extend and loop video clips for backgrounds, ambience, and digital displays.
Film Production
Extend shots that ended too early. Additional footage for editing flexibility and scene pacing.
Extend any video with a single click
Upload your clip, choose a direction, and let AI generate seamless extra seconds. No editing skills needed — extend forward, backward, or both.
