When should reference images, start frames, or end frames be used?

Reference inputs are essential for continuity and consistency.

• Image references guide visual style, subject appearance, and composition.
• Start frames establish the opening visual state for a video.
• End frames control how motion resolves or transitions.

These tools are especially important when:

• creating multiple assets for one campaign
• maintaining character or product consistency
• building sequences that will be edited together

Prompting alone is rarely sufficient for continuity across multiple generations.
