Text is the best starting point when the idea depends on a sequence, opinion, lesson, or imagined scene. Describe the subject, setting, camera behavior, action, and intended feeling in plain language. A page link is useful when a business already has accurate source material and needs a Reel derived from it. Select one story from that page rather than trying to compress every section. Reference images are strongest when visual continuity matters, such as a product, person, location, palette, or established campaign look.
The input should reduce uncertainty. A vague prompt followed by several unrelated images can create more ambiguity than a short, specific brief. State which parts of the references must remain consistent and which parts can change. For example, keep the product shape and label accurate while changing the setting, or preserve the subject while exploring different camera distances. That distinction makes it easier to review the result because the team knows what was fixed and what was intentionally open to interpretation.
