Question 1

Which videos can I extend?

Accepted Answer

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.

Question 2

Do I need to provide a prompt?

Accepted Answer

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

Question 3

Will the extended video match the original style?

Accepted Answer

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

Question 4

What is the maximum resolution?

Accepted Answer

SD 2.0 supports up to 2K resolution output, maintained through the extension.
