What we like
- Generation and editing in one place: Gen-4.5 for clips, Aleph 2.0 for edits
- Edits can change only what you ask for and keep the rest of the footage
- Professional export formats such as ProRes and PNG sequences
Watch out for
- Credit-based use can add up when you iterate
- Generated clips are short, so longer videos need editing together
- Motion can be unpredictable, so expect to regenerate
Runway is a creative platform for AI video. Its generation models make new clips; its editing models change footage you already have.
What is current
- Gen-4.5 reached the Runway API on February 10, 2026. It makes 2 to 10 second clips from text or from an image.
- Aleph 2.0 launched on May 21, 2026 with a new Edit Studio. It edits existing video up to 30 seconds at 1080p from text prompts, and Runway says it makes targeted edits that keep the rest of the clip as it was.

How prompting works
Describe the subject, the camera movement and the light, one shot at a time. For edits, say what should change and what must stay the same.
Who should use it
Creators who want quick motion or want to restyle footage without a reshoot. Plan for several attempts per clip and watch credits. Compare it in Veo vs Kling or see the best AI video generators.
