AI video generation and control
Investigate motion, identity, continuity, avatars and controllable video workflows.
What we currently think
A convincing demo does not establish production control. Identity, temporal continuity, editability and repeatability fail independently.
Start with your question
- What does this model actually control?
- Which failure appears across repeated generations?
- Can the result survive a real production workflow?
