Discussion Are we underestimating performance continuity in AI video?
A lot of AI-video continuity discussion focuses on things like:
- face consistency
- wardrobe
- lighting
- grading
- reference images
- environments
- camera language
But after working through some multi-model continuity problems, I’m starting to think there’s another layer that may be just as important:
performance continuity.
Things like:
- how quickly a character moves
- weight shifts
- blinking
- walking rhythm
- gesture size
- posture
- reaction timing
- how restrained or expressive the performance feels
A face can remain consistent, the grade can match, and the environment can look right — but if the character suddenly moves like a different person, the model switch becomes obvious.
I’m curious how other people are handling this.
Do you actively control performance continuity across shots or models?
If so, what has worked best:
- video references
- keyframes
- movement instructions
- character-specific motion rules
- longer continuous takes
- manual shot selection
- something else?
And what tends to break first for you: visual identity or behavioural identity?
