Qu'est-ce que la generation de video par IA ?
La generation de video par IA utilise des modeles de deep learning pour creer des clips video a partir de prompts textuels, d'images ou de sequences existantes. En 2026, les equipes comparent Seedance 2.0, Sora 2, Kling 3.0 et Runway Gen-4 sur le realisme, la duree, le controle creatif, le prix et l'adequation au workflow.
Comment fonctionne la generation de video par IA
Concepts cles de la creation video par IA.
Modeles de diffusion
La plupart des generateurs video IA utilisent des modeles de diffusion qui partent d'un bruit visuel et le reduisent progressivement pour produire des images coherentes, guidees par votre texte ou image d'entree.
Texte vers video (T2V)
Saisissez une description et l'IA genere un clip video correspondant. Des modeles comme Sora 2 produisent des clips allant jusqu'a 20 secondes a partir d'un seul prompt.
Image vers video (I2V)
Telechargez une image fixe et l'IA l'anime en video. Le mode Director de Seedance 2.0 accepte jusqu'a 12 images de reference pour une sortie multi-plans coherente.
Video vers video (V2V)
Fournissez des sequences existantes et l'IA les transforme en changeant le style, en augmentant la resolution ou en modifiant le contenu tout en preservant le mouvement. Runway Gen-4 excelle dans les controles de transfert de style.
Coherence temporelle
Le plus grand defi de la video IA : maintenir la coherence des sujets, de l'eclairage et de la physique entre les images. Le verrouillage de visage et la prediction de mouvement repondent a ce probleme.
Modeles de tarification
La plupart des outils proposent des formules gratuites (5-30 generations/mois) avec des forfaits payants de 8 a 30 $/mois. Les options open source comme Wan 2.6 peuvent etre auto-hebergees gratuitement.
