Learn more about reference-to-video generation

Tell your agent what each reference is meant to control, such as identity, wardrobe, product detail, composition or visual style. Clear roles prevent the references from competing with one another.

Assign one purpose to every reference

Label the authoritative image for identity or product appearance and explain what to borrow from supporting references. State which differences are intentional and which details must remain consistent.

How many references should I provide?

Use the smallest set that resolves the visual brief. Extra references can introduce contradictory faces, palettes, proportions or environments, so remove any image that does not control a specific quality.

Test continuity in a simple shot

Begin with a short action and restrained camera movement. Check identity, object geometry, wardrobe, style and background continuity before attempting a complex sequence.

Example prompt

This example gives two references distinct jobs.

Example prompt to give your agent

Use Scrollport's Reference-to-video capability to create a [DURATION] shot for [USE]. Use [REFERENCE A] as the authority for [IDENTITY OR PRODUCT] and [REFERENCE B] only for [COMPOSITION OR STYLE]. Show [ACTION] in [SETTING] with [CAMERA MOVEMENT]. Preserve [DETAILS], ignore [CONFLICTING REFERENCE DETAILS], and show me the price before the paid run.
