FAQ

What is AI outpainting?

A generative method that synthesizes new pixels outside the original frame, extending the scene logically to wider or taller compositions.

What videos work best?

Clips with stable, predictable motion—drone moves, camera pans, or straight‑line subjects—tend to produce the cleanest results.

How long can I extend a clip?

Limits depend on plan. Free tiers allow short extensions; Pro plans unlock longer durations and faster processing.

Is the generated content original?

Yes. The extended portion is newly generated from your clip's context, creating unique frames for your project.
