Runway ML
Runway is the go-to platform for AI video creation and editing. From text-to-video and image-to-video generation to AI-powered editing tools, Runway is used by filmmakers, content creators, and marketing teams worldwide.
How to Get the Most Out of Runway ML
Generate Cinematic B-Roll from Text for Video Projects
Use Runway's Gen-3 Alpha with a detailed scene prompt: "Aerial drone shot over misty mountain peaks at sunrise, golden hour light, slow pan left, cinematic aspect ratio." Generate several variations and select the best clip for your edit. For documentary, commercial, and corporate video work, AI-generated b-roll can replace expensive location shoots for establishing shots and abstract sequences that set tone rather than tell story.
Remove Backgrounds and Objects from Video with AI Tools
Upload any video to Runway and use the Background Removal tool to isolate subjects without a green screen — it handles complex edges like hair and moving backgrounds reliably. Use the Inpainting tool to remove unwanted objects (a microphone stand, a bystander, a logo) automatically. These post-production capabilities used to require expensive software and hours of manual masking; Runway handles them in minutes.
Use Motion Brush to Control Exactly What Moves in Your Video
Upload an image, click the Motion Brush tool, and paint over specific areas to tell Runway which elements should move and in what direction — paint the clouds to drift left, the water to flow down, the hair to move in the wind. This level of directorial control over AI-generated motion is unique to Runway and produces more intentional results than text-only motion prompts.
Our Take
Runway is the most complete AI video platform — it combines generation with professional post-production tools in a way no competitor matches. The Motion Brush and background removal features are genuinely useful for working video editors, not just AI novelty. For pure generation quality on cinematic clips, Luma AI sometimes produces more impressive single outputs, but Runway's full toolkit makes it more valuable for professional workflows. The credit-based pricing can add up quickly for high-volume use — calculate your expected usage before committing to a plan.
