# AI videos with no cuts and no drift

AI galaxy · Cédric Merlin, CTO · https://merlin-cedric.fr/en/ia/video-ia/

Routing between video models, a frame-by-frame automatic judge, hidden-cut detection and joins on the last real frame, with cost tracked per call.

## The problem

Video-generating models cut, drift and make things up, without warning.

## What I did

1. **The right model.** I choose the model according to the shot (Kling, Seedance, MiniMax, Wan).
2. **A judge checks.** An automatic judge checks every frame.
3. **Hidden cuts.** A script detects hidden cuts.
4. **A seamless join.** Each clip restarts from the last real frame of the previous one: no jump.

## The result

Clean joins and a cost tracked call by call.

## Watch

From zero to this result: character, set, motion and editing, all generated by AI.
