๐ŸŽฌ Consistency is the hard problem in AI video

PM AI Video Products
(2026 Edition)

Character consistency across frames is the hardest unsolved problem in AI video, since footage drifts mid-shot even as Sora and Runway push clip length past ten seconds; PMs track this through re-roll rate and seconds of final video produced per user, while rights and likeness stay a legal landmine that avatars need explicit consent to avoid โ€” which is why hybrid pipelines pairing AI B-roll with human production dominate 2026 workflows.

5 Dynamics

1.

Consistency across frames is the hard problem โ€” characters drift mid-shot

2.

Length limits matter โ€” Sora and Runway push past 10s, but cost and coherence fall off

3.

Generation vs editing โ€” two different product shapes, often in one tool

4.

Rights and likeness are legal landmines โ€” avatars need explicit consent

5.

Workflow integration matters for pros โ€” plugins into Premiere, DaVinci

5 Metrics

1.

Seconds of final video produced per user

2.

Re-roll rate (how many attempts before a keeper?)

3.

Upgrade conversion to longer/higher-res tier

4.

Professional workflow integration adoption

5.

Safety incident rate

FAQ

Will AI video replace traditional video production?

For short-form social and advertising, it's already taking share. For long-form narrative, the ceiling is still meaningfully below human production. Hybrid pipelines (AI for B-roll, motion graphics, previsualisation) are where most production studios land in 2026.
