Runway ML Pros
- Gen-4.5 produces the most coherent AI video on the market right now
- Credit system lets you pay only for what you actually render
- Full editing suite (inpaint, outpaint, motion brush) built into the same platform
- API available for developers who want programmatic access
Runway ML Cons
- Credits burn fast at 15 per second for top-quality output
- Free tier only gives 125 one-time credits — barely enough to test
- No native audio generation — you still need separate music and voiceover tools
- Longer clips (30s+) still struggle with scene consistency
