Chaîne multi-modèles pour la vidéo IA
The idea that a successful AI video doesn't come from a single model, but from a chain where each link does what it does best: a seed image to set the art direction, a model that generates shots with character and lighting consistency, a premium model for hero shots, a voice, then an edit. In 2026 nobody in serious production leans on ONE model: multi-model has become the silent standard, because Veo excels on hero and audio, Seedance on continuity between cuts, Kling on linked shots, Runway on marketing edits. Each has a strength, none covers everything.
Strengths
- Each shot is better: you use the strong model on its specialty instead of an average generalist everywhere
- Budget under control: you reserve costly premium models for hero shots only, not for B-roll
- Resilient to a volatile domain: the grid stays true even as models change every month
Limitations
- More moving parts to orchestrate than a single tool: you must know how to hand an artifact from one link to the next
- Requires some perspective on each model's strengths, a knowledge that dates fast in a fast-iterating domain
Best for
- A designer or PM who wants to produce a full short video (promo, explainer, teaser) and wonders where to start
- Someone who tried a single video generator, was let down by the result, and wrongly believes "AI video isn't ready"
