Runway is a browser workspace for generating, transforming, and assembling video. For this review, we assessed Gen-4.5, Aleph 2.0, Act-Two, exports, model retirement, workspace billing, and the 2026 plan transition.
Gen-4.5 is the current flagship. Motion physics, subject consistency, and lighting behavior approach professional VFX quality on the right prompts. The output has that “convincing for a few seconds before you notice the AI” quality, which sounds like faint praise until you realize that window was zero seconds two years ago.
The creative controls are what separate Runway from everything else. Motion Brush lets you select specific regions of an image and animate them independently: move the water without touching the sky, animate hair while the body stays still. Camera Controls give you cinematographer-level specification of shot type, movement speed, and trajectory. Act-One transfers motion and expression from reference video to AI characters. These aren’t gimmicks. They’re production tools that give you the kind of control that turns random generation into directed filmmaking.
Aleph is the post-generation editor that arrived in 2025 and changed the workflow entirely. Instead of regenerating an entire clip when one detail is wrong, you can prompt changes within the existing video: “add rain,” “change the lighting to golden hour,” “remove the background object.” It understands spatial relationships and maintains temporal consistency. For production teams, this is worth the subscription on its own.
Credits are the pain point. Standard clips cost 5-10 credits. Gen-4.5 at higher quality costs 12 credits per second. A 10-second 4K clip can consume 100+ credits. The Pro plan at $28/mo gives you enough for roughly 125 seconds of Gen-4 Turbo or 52 seconds of Gen-4 Standard. Active creators burn through a month’s allocation in a few days. The free tier offers 125 one-time credits, watermarked at 720p. It’s enough to see what Runway can do, but not enough to do anything with it.
