Full 2K Workflow (optionnel) : ① Context-IR enrichit le prompt → ② MiniMax-H3 en 768P pour un aperçu → ③ Regeneration monte en 2K. Les prix unitaires combinés correspondent au 2K direct, avec des itérations moins chères. Vous pouvez aussi appeler cet endpoint seul.

Aperçu

Envoyez votre idée et éventuellement des médias pour une compréhension multimodale ; recevez un prompt structuré et plus riche.

Aucune vidéo n’est produite. Le résultat est dans result.prompt (pas result.videos)
Les champs médias utilisent les mêmes règles de validation que la génération vidéo (exclusion mutuelle trames vs références ; l’audio ne peut pas être seul), afin de réutiliser les mêmes entrées pour la génération

      "prompt": "integrated_multimodal_description: [Shot 1] Cinematic, close-up shot. The camera slowly pushes in on a lone adult astronaut standing in a dimly lit, metallic corridor. The astronaut wears a weathered, white and silver extravehicular spacesuit heavily scuffed with grey dust, featuring a completely opaque, gold-tinted helmet visor. The astronaut slowly pushes open a rusted, thick steel airlock door on the right side of the frame. As the heavy metal door shifts, a sudden, intense beam of vibrant green light spills across the dark frame, illuminating the intricate fabric folds of the suit. The curved golden visor vividly reflects a dense, tangled mass of luminescent green leaves and vines. [Shot 2] At 00:02.500, the camera cuts to a wide shot from directly behind the astronaut from Shot 1, smoothly pedestaling up to reveal the interior of the abandoned orbital station. The vast, hexagonal titanium room is completely overrun by a lush, zero-gravity living garden. Giant, emerald-green vines spiral tightly around cracked, grey ceiling support beams, while thick patches of bioluminescent cyan moss emit a soft glow from the rusted floor grid. Several large, perfectly spherical water droplets float weightlessly in the midground, refracting the ambient green light. The astronaut lowers their heavy, white-gloved hands to their sides, standing perfectly motionless before the massive canopy of overgrown flora.\noverall_soundscape: A loud, grinding metallic creak dominates the foreground as the heavy steel door shifts, instantly followed by a pronounced, high-pitched hiss of escaping pressurized air. A continuous, low-frequency mechanical hum rumbles in the background, establishing the station's deadened room tone. As the space opens, the distinct, crisp rustle of thick foliage is clearly heard, accompanied by soft, resonant liquid plops as unseen water drops collide in the metallic chamber.\nnon_diegetic_music: Ambient electronic score, slow tempo, featuring a deep, sustained synthesizer drone heavily overlaid with delicate, shimmering glockenspiel notes and a solitary, reverberating cello."

Paramètres de la requête

string

requis

Valeur fixe : MiniMax-H3-Context-IR

string

requis

Texte d’idée original, ≤ 7000 caractères

integer

défaut:"5"

Durée cible de la vidéo (secondes), 4~15, défaut 5. Influence le langage de rythme dans le prompt enrichi.

string

Ratio d’aspect cible. Obligatoire pour une entrée texte seule, et ne peut pas être adaptive.Valeurs courantes : 16:9, 9:16, 1:1, 4:3, 3:4, 21:9, etc.

string

URL de l’image de première trame

string

URL de l’image de dernière trame

string[]

Images de référence (toujours traitées comme références), ≤ 9

object[]

Images avec rôles : first_frame / last_frame / reference_image

string[]

Vidéos de référence, ≤ 3 ; chacune 2~15 s, total ≤ 15 s

string[]

Audio de référence, ≤ 3 ; ne peut pas être utilisé seul — associez-le à une image ou une vidéo

Facturation

Basée sur les tokens (seul modèle de la famille H3 facturé aux tokens) :

Élément	Prix
Tokens d’entrée	$0.87 / million
Tokens de sortie	$3.45 / million

Un appel typique (~5,6k entrée + ~3,4k sortie tokens) coûte environ $0.0167. Un dépôt fixe est prélevé à la soumission, puis régularisé sur les prompt_tokens / completion_tokens réels (remboursement de l’excédent / complément). Les entrées multimodales augmentent fortement les tokens d’entrée.

Notes

Habituellement 20~40 secondes ; interrogez le statut de tâche toutes les 3~5 secondes.
Mauvais paramètres → 400 synchrone (pas de tâche, pas de facturation) ; échecs d’exécution → failed avec remboursement auto.
Les notes du workflow complet sont sur la page Regeneration.
