Sound with the picture
Every scene is written with its diegetic sound, and Seedance 2.5 generates the audio in the same pass as the frames. It is in the clip and in the price.
Seedance 2.5
Longer narratives. Better control.
Up to 30 seconds a shot, written as timed beats.
Seedance 2.5 renders 4 to 30 seconds in one generation, and reads a prompt the way this studio writes one: 0 to 3 seconds does one thing, 3 to 7 the next, and the beats come back in order. Cut the scene into shots, or ask for one take.
- Each shot's window is fitted to a clip length Seedance renders, 4 to 30 seconds.
- Six frames from 21:9 to 9:16; image-to-video keeps the keyframe's framing.
Timed beats · three cuts in 6 s
Smarter reference
Held to your photos from the first second to the last.
Every shot's first frame is drawn from the references you attach, and a scene with none never reaches the Queue. Seedance 2.5 keeps a product or a face the same at second one and second twenty-eight, and each shot's keyframe carries the previous shot's still for continuity.
- Upload photos for one scene, or save a person, product or place as an element and reuse it.
- The keyframe you approved is what the clip starts on, image-to-video.
Product held steady
Audio and picture together
Sound is generated with the frame, not laid over it.
Every scene this studio writes ends in its diegetic sound: the footstep, the room tone, no music bed. Seedance 2.5 decides picture and sound in the same pass, so the footstep lands on the frame the foot does, and the audio is included in the clip's price.
Native audio sync
Aiming for production
Priced before you spend, assembled when you approve.
Draft a scene at 480p for under half the 720p rate, look at every keyframe, then approve the tier, length and frame per shot with the credits on the card. The clips assemble in shot order into one MP4, loudness-normalised, with an optional music bed under them.
- Seedance 2.0 Fast and Seedance 2.0 stay on the same card for a quicker or a 1080p take.

One scene, three timed shots
Each shot is its own Seedance 2.5 clip.

Shot 1 of 3 (0–5s): Wide, static. A ceramics studio at dawn: the potter at the wheel by the window, one bulb burning over the shelves. Sound: the wheel's low hum, a bird outside.

Up to 30 seconds a shot
Each shot's window is fitted to a Seedance 2.5 clip length between 4 and 30 seconds, twice what 2.0 renders, in one generation.
- 03
Timed beats, in order
A scene is written as timed windows, which is the prompt shape Seedance 2.5 reads best: 0 to 3 seconds one thing, 3 to 7 the next, returned in order.
- 04
One take, or a cut
The writer cuts a scene into shots by default and writes one continuous take when you ask for it. On Seedance 2.5 either renders.
- 05
Image to video, from your photos
Each shot renders image-to-video from a keyframe drawn from the references you attached, so the clip starts on your product, person or place.
- 06
Keyframe first
Draw every shot's first frame in the Queue before a clip is rendered, with the credits on the button before you press it.
- 07
Draft cheap, then approve
A 480p draft costs under half the 720p rate. The Queue prices the exact tier, length and frame you picked, and that number is what is charged.
- 08
Reusable elements
Save a character, prop or place as an element and every scene written against it is held to the same frames.
- 09
Export one MP4
Assemble the Seedance clips in shot order into one MP4, loudness-normalised, with an optional music bed under them.
