Runway ML
Runway is an AI video platform built around generative world models — Gen-4.5, Aleph 2.0, and Act-Two for performance capture — split across Runway Creative for filmmakers, Runway Dev for builders, and Runway Robotics.
- Most complete AI video toolset for genuine production work
- Aleph transforms real footage, which gives far more control than pure generation
- Act-Two solves the uncanny performance problem better than prompt-driven acting
- Characters and Workflows make multi-shot sequences realistic to attempt
- Clips remain short, so longer pieces must be assembled and matched
- Control is coarse — directing a specific result takes many attempts
- Hands, on-screen text, and complex physical interaction still fail visibly
Seedance 2.5 AI
The site at seedance2-5ai.im is a browser workspace, operated by Jev AI, for generating video with ByteDance's Seedance 2.5 model and others — up to 4K and 30 seconds with native audio, from text, a frame or references, priced in credits.
- Native audio removes a whole sound-design step for ambience
- Strong reference control keeps identity consistent across a shot
- Longer, higher-resolution clips than much of the short-video field
- Model choice and transparent credit cost in one interface
- Quality is the underlying model's, not the front-end's
- Availability and terms are set upstream and can change without notice
- A model-named domain means you must confirm you are in the right place
