How long can I extend a clip?

You can add 2 to 15 seconds per extension. For longer results, run multiple extensions sequentially on the same clip.

Will the extended portion look different from the original?

The system analyzes the original clip's color grade, lighting, and motion patterns to generate a visually consistent continuation. In most cases, the seam is undetectable.

Can I extend in both directions?

Yes. You can add frames before the start or after the end of your clip, useful for creating lead-ins or extending outros.
