Common Questions

Frequently asked

Which videos can I extend?

You can extend any video generated by SD 2.0 (sd-v2.0-t2v or sd-v2.0-i2v). Provide the request_id returned by the original generation.

What's different from sd-2-vip-extend?

Output resolution. sd-2-vip-extend-1080p produces full 1080p, while sd-2-vip-extend produces 720p. The 1080p variant costs roughly 2.25× more per second.

Will the extended video match the original style?

Yes. The model preserves visual style, character identity, motion physics, camera movement, and native audio consistency across the extension.

Do I need a prompt?

No, the prompt is optional. If omitted, SD 2.0 intelligently continues the scene based on the original video's content, motion, and style.
