Runway Gen-4.5 Guide

Runway flagship generation model with professional/HDR output options. This page connects the model data to working GenVideoKit prompt, image-to-video, comparison and cost tools.

Prompting strategy

Use direct production language: subject, environment, action, camera, lighting, timing and final state. Keep motion coherent and controllable. Avoid vague style-only prompting; describe what visibly changes over the shot and preserve reference identity when applicable.

How to use Runway Gen-4.5 in a production workflow

Catalog checked 2026-09-20

Reference-led workflowsThis catalog entry includes reference-oriented controls. Use the source frame or reference asset to define appearance, then keep motion and camera instructions separate from identity constraints.

Text-to-video baselineFor text-only generation, specify subject, one dominant action, camera behavior, environment and final composition before adding style language.

Questions to answer before choosing the model

Does the workflow require a reference image, first/last frame, keyframes or video input?
Is synchronized audio or lip sync a hard requirement, or can sound be added in post?
How many retries can the project budget tolerate before the cost advantage disappears?
Will the final delivery need several aspect ratios or should composition be generated natively for each format?
