How It Works

Extend Any Video in Three Steps

No timeline, no plugins, no reshoots. Upload your input, tell the AI what happens next, and download a longer clip.

1

Upload a clip or a still image

Drop in the source video you want to continue, or a single frame to animate. The generator reads your footage to understand motion, lighting, and subject before it extends anything.

2

Describe the continuation and pick a model

Write a short prompt for what should happen next, then set duration, aspect ratio, and audio. Choose the AI model that fits your clip — from fast turnaround to cinematic motion.

3

Generate in the background, then download

The AI renders new frames that pick up where your clip ends. Preview the result, regenerate with a tweaked prompt if needed, then download the finished video.

Tips for the Best Results

A few habits that make AI extensions look natural instead of glitchy.

Start with clear motion

Source clips with a readable subject and steady framing extend far more predictably than fast cuts or heavy motion blur.

Upload 720p or higher

A sharp, well-lit source gives the model clearer visual context. Output resolution and detail still depend on the selected model and settings.

Write specific prompts

Describe direction, speed, and what enters the frame. "Camera keeps following the subject forward" beats a blank prompt every time.

Keep durations short

Use the duration choices offered by the selected model. Shorter outputs can be easier to keep consistent when multiple options are available.

Match the aspect ratio

Where the selected model supports it, choose an aspect ratio for the destination before generating to reduce later cropping.

Iterate the prompt first

If a result misses, refine the prompt before switching models. It's the cheapest, fastest lever on the outcome.

FAQ

Using the Generator

Practical answers about uploading, generating, and downloading your extended clips.

For video-to-video, upload the source clip you want to continue. For image-to-video, upload a single still frame. Common formats are supported and the file limit is 50MB — trim or compress longer clips before uploading if needed.

Turn a Short Clip Into a Longer Scene

Upload the footage that stops too soon and keep it moving with AI continuation that respects the original shot.
