Hello les Cocréateurs,
ByteDance a sorti Seedance 2.5, hier vendredi 31 juillet.
La nouveauté principale, c’est la durée : 30 secondes générées en une seule passe, là où la 2.0 plafonnait autour de 15.
L’autre gros morceau, c’est le nombre de références acceptées : jusqu’à 30 images, 10 vidéos et 10 fichiers audio dans une même entrée. Plus de l’édition ciblée par timestamp et du fond vert.
On peut tester ça sur Dreamina ou CapCut. J’ai l’ai testé hier en mode avatar sur CapCut.
Voici ce que ça donne sur une scène de mon Odyssée, avec le prompt complet :
Le prompt :
« L’Odyssée »
CHARACTER: @Jeanviet (use avatar). Face fully visible throughout.
Ancient Greek hero outfit: off-white linen tunic with leather chest
strap, bronze arm guards, brown leather sandals, red cloak. On his
head: a burgundy NY baseball cap — worn in every single shot, never
removed (signature running gag).SECONDARY: @Clara (use avatar). Teenage girl. Athena costume: flowing
white and gold robe, bronze breastplate, golden laurel crown, spear
in hand. Face fully visible.CYCLOPS: a giant one-eyed humanoid, 4 meters tall, muscular, rough
skin, single large eye in the center of his forehead, wearing rough
animal hides.Style: photorealistic epic cinema, Mediterranean light, Ridley
Scott-style color grading — warm gold, deep shadows, dust particles.0–5s — Le nom
Interior of a dark rocky cave, firelight flickering. Hero stands small
in the frame facing the towering Cyclops seated above him. Hero looks
up calmly, hands behind his back.
DIALOGUE (French, calm and confident): « Mon nom est Personne. »
Camera: low angle from behind the hero, emphasising the Cyclops’ scale.5–9s — Le pieu
Hero seizes a long wooden stake, its tip glowing red-hot from the fire.
He runs forward with three companions, they raise the stake together
and drive it into the Cyclops’ single eye. Bright flash, sparks and
smoke. The giant recoils backward, roaring, hands over his face.
Camera: fast tracking with the stake, then hard cut to a wide shot of
the giant staggering.9–13s — L’embarquement
Exterior, rocky Mediterranean shore at dawn. Hero runs down to a
wooden Greek galley, sail unfurling. His soldiers in bronze armour
push the boat into the water and climb aboard. Hero leaps onto the
deck last, cloak flying.
Camera: side tracking of the run, then wide shot of the ship leaving
shore.13–19s — La colère de Poséidon
Open sea, violent storm. Towering black waves crash over the deck,
rain lashing, lightning splitting the sky. A colossal figure of an
ancient sea god rises from the water in the background — bearded,
crowned, holding a trident, made of water and foam. He slams the
trident down, a giant wave tilts the ship almost vertical. Hero grips
the mast with one hand, holding his cap on with the other, shouting
into the storm.
Camera: handheld chaotic shots on deck, then wide shot of the ship
against the wave.19–24s — Ithaque
Calm returns. Golden sunset. The galley reaches a quiet rocky bay
with olive trees and white stone buildings on the hills. Hero steps
off the boat onto the sand. Clara, dressed as Athena, walks toward
him and embraces him.
DIALOGUE (Clara, French, warm): « Papa, bienvenue chez toi. »
Camera: wide shot of the arrival, then medium two-shot on the embrace.24–28s — La colline
Hero and Clara walk up a grassy hill together, side by side, backlit
by the setting sun. They reach the crest and look down. Below them,
a huge Greek crowd in white tunics fills the valley, cheering, arms
raised, waving olive branches.
Camera: tracking behind them up the hill, then reverse to reveal the
crowd below.28–30s — Le dézoom
Camera pulls back rapidly into a vast aerial shot — the two silhouettes
on the hill, the crowd below, the sea and the galley in the distance.
Bold golden text appears centred on screen: « JEANVIET IS BACK ».
Camera: fast dezoom to extreme wide, freeze frame.CONSTRAINTS: 16:9. Both faces fully visible (use avatars). Burgundy NY
cap on the hero in EVERY shot including the storm. Photorealistic epic
cinema throughout. Crowd faces blurred or distant. No brand names or
logos.
Petit tuto pour créer une vidéo Seedance dont tu le héros, change Seedance 2.0 par Seedance 2.5
Mon retour : l’enchaînement des plans en un seul prompt est bluffant, la cohérence du personnage tient sur les 30 secondes. Les deux limites que j’ai rencontrées : le rendu en 720p et le coût par génération, qui monte vite quand tu itères.
Vous l’avez testé de votre côté ? Ça donne quoi sur des scènes plus calmes ?
