Wan 2.2 Spicy LoRA API

Wan 2.2 Spicy LoRA Video extend continues an existing clip from its final frame for another 5 or 8 seconds at 480p or 720p. It accepts the same three LoRA lists as image-to-video, so the weights that styled the first pass can be attached again to the next segment. They are not inherited from the source clip and have to be sent on every call.

Choose a Wan 2.2 Spicy LoRA mode by starting material

The style carries over because you repeat the weights

A LoRA attached on the first pass does not travel inside the rendered clip. Send the same links at the same strengths on every extension and the look is carried into each segment instead of being rebuilt; change a weight or its strength between passes and the render treatment shifts at the seam. Every extension is still a fresh generation, so small rendering shifts can creep in and each join deserves a look.

The output includes the source footage

The returned video starts with the clip you supplied and then continues it, so it runs longer than the seconds you requested. Trim the source portion before splicing the new material onto your original edit, otherwise the source seconds play twice.

Length built one segment at a time

Each call adds exactly five or eight seconds. A longer scene is built by feeding each approved segment back in as the next source, which means every segment can be reviewed and rejected before the next one is paid for. Keep the resolution of the source clip: switching between 480p and 720p partway through a chain shows at the join.

Continue a LoRA-styled clip for eight more seconds

The published extend-the-stack example takes the 720p clip made on image-to-video with three stacked LoRAs and asks for eight more seconds: she turns away from the light and the satin falls off the other shoulder. The prompt covers only the new movement, which starts out of a hold, and the same LoRA set is attached again rather than inherited.

Test the seam with no LoRA at all

The tail-rise-continue example extends a 720p clip by five seconds without any LoRA, to show the join on its own terms: she rises off her knees, a plush tail sweeps a slow arc across the rug and she turns fully to camera. Deep crimson lamplight and film grain have to cross the seam unchanged, which makes it a useful baseline before you judge whether a LoRA is causing a shift.

End a sequence on a hold that can still be extended

The closing-hold example asks for eight seconds with a locked camera and seed 640022: she stops at the top of the stairs, looks back toward the crypt and holds still as the candles steady behind her. Finishing on a settled pose gives the edit a clean ending and keeps a further extension possible, because extensions join most cleanly from a still final frame.
