How to write Runway Gen-4 and Gen-4.5 prompts with image-plus-text workflows, continuity anchors, and shot-safe pacing.
Runway Gen-4 workflows are strongest when text prompts are paired with reference imagery. This improves consistency for characters, products, and environment details.
Treat the image as identity anchor and text as motion and camera instruction.
Use short motion beats with explicit camera language. Keep each shot to one primary action and one transition intent.
When teams ask how to adapt one prompt across models, this pattern usually ports well to Kling, Veo, and Seedance too.
Repeat wardrobe, props, and scene constraints in every shot block. Do not rely on memory from earlier prompts.
Use short blocks, evaluate output, and continue from the best block instead of rewriting from scratch.
