BigMotion
AI video studio for ads, faceless shorts and music videos Category: Video & Audio.
- Covers ads, faceless shorts and music videos in one studio
- Auto-posts content across multiple platforms

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
