What this tool does
Extending a clip is a continuity problem. The preset tells the model to continue from the final frame, keep the same subject, camera direction, color grade and lighting, and avoid a cut. Use a clip with a stable final frame. If the original ends mid-motion or with a fast camera move, the extension has less information to work from.

Questions people ask
Does it keep the original audio?
The extender works on the visual clip. Check the studio's audio field and your downstream edit for sound.
Can I extend by more than five seconds?
The duration control is in the studio. Longer extensions cost more credits and are more likely to drift.
What if the last frame is blurry?
The model has less to work with. Trim to a sharper frame before uploading if your editor allows it.
