Runway is both a video generation model (Runway Gen-4.5) and a full suite of creative tools in the browser.
Who it’s for
Filmmakers and studios who want to direct their shots: camera movement, framing, transfer of an actor’s performance.
What it does well
- Control: camera moves, the motion brush and image references give you real directing power.
- The tool suite: rotoscoping, slow motion, image expansion and editing in one place.
- Performance transfer: an actor filmed on a phone drives a generated character.
Limitations
Credits go fast on long shots, and the interface takes some getting used to.
Alternatives
Pika for quick effects, or the Seedance 2.5 and Kling 3.0 models for better value for money.
