Direct answer

Video extension prompts should preserve the existing clip state and add only the next visible beat.

Publication and release gate

• Curation gate: this page can stay public only while curationStatus is published.
• Rights gate: source rights must be known, non-blocked, and attribution must remain visible.
• Discovery gate: public HTML, Markdown, llms.txt, sitemap, and search-index entries are generated only from published records.
• Official-source policy: paraphrase BytePlus or paper material and cite the original source.

Prompt reuse checklist

• Name the exact input type: text, image, audio, video, first frame, or final frame.
• State what each reference controls so the model does not blend competing instructions.
• Use one camera move, one main action, and one final-frame payoff.
• Test the smallest version in HolyCrab before expanding the shot.

Reusable pattern

Video extension prompts should preserve the existing clip state and add only the next visible beat.

Rewrite rule

Keep the capability structure, then replace subject, reference role, camera, action, and final-frame payoff.

Source evidence

Use video extension when a clip needs a second beat, a longer payoff, or a continuation that respects the previous motion and style.

HolyCrab next step

Test the smallest official-style Seedance prompt in HolyCrab before adding more reference inputs.

Prompt pattern

Continue from the current final frame, preserve subject identity and camera direction, then describe the next action.

Example prompt

Continue from the last frame. The camera keeps drifting backward as the astronaut slowly turns toward the blue planet, visor reflection staying consistent.

Common failure modes

Prompt restarts instead of continuing; Style changes between clips; The continuation introduces too many new objects

Recreate with HolyCrab Seedance

1. Start with the source-attributed Seedance capability or example brief.
2. Name each input type and what it should control.
3. Write one camera path and one final-frame payoff.
4. Generate a short HolyCrab test, then revise only the weakest prompt variable.
