Model comparison
Reference costs come from the current GenVideoKit model catalog and may differ from consumer plans, promotions, regional pricing or third-party API markups. Models are not ranked; this tool exposes differences so you can choose for your own workflow.
Luma AI
Luma Ray 3.2
Current Luma video model with frame-level control and HDR/EXR workflows.
Text → videoImage → videoKeyframesHDREditingReframe
Prompt emphasis: Think like a director using keyframes and shot control. Define composition, action trajectory, camera path and the desired ending frame/state. Keep movement continuous and avoid contradictory instructions; use precise visual transitions rather than abstract mood language.
Runway
Runway Gen-4.5
Runway flagship generation model with professional/HDR output options.
Text → videoImage → videoProResHDR
Prompt emphasis: 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.
