character consistency failureidentity driftface changes between frames
What it means
The subject changes across frames because the prompt lacks stable identity anchors or reference handling.
Most common causes
- No reference image
- Too many descriptors
- Long shot duration
- Changing lighting or wardrobe
Fastest fix
- Reproduce the smallest failing case.
- Check environment, platform, and production settings.
- Use the related local tool to classify the issue.
- Fix the highest-risk security or data issue first.
Safe fix
- Keep secrets out of client code and logs.
- Prefer least privilege and explicit allowlists.
- Add a regression test or checklist before retrying.
- Document the working production configuration.
What not to do
- Do not disable security controls as a permanent fix.
- Do not paste secrets into public issue trackers or AI chats.
- Do not trust preview success as production readiness.
