What is Seedance 2.5?

Seedance 2.5 is ByteDance's flagship video model. It writes clips of up to 30 seconds from a prompt, a starting image or a big pile of reference photos and clips, and it generates the sound in the same pass so footsteps, voices and room noise land on the right frames.

Best on PopNow for: Longer single takes, product films that start from an approved packshot, and series where a character has to look identical across many clips.

Good for

Product films that start from an approved packshot
Recurring characters who look the same from one episode to the next
Atmospheric scenes where sound matters, like a busy bar or a train platform

What Seedance 2.5 does well

Up to 30 seconds in one take

Most video models stop at 10 or 15 seconds. Seedance 2.5 goes to 30, which is enough for a full product reveal or a short scene without stitching. In practice takes stay cleanest up to about ten seconds, so longer clips work best when the action is simple.

Thirty references at once

Reference mode accepts up to 30 images, 10 clips and 10 audio tracks. Three angles of one face hold a character together far better than one photo, and a reference clip can set the camera rhythm you want to copy.

Sound that fits the room

Audio is on by default and comes out of the same generation as the picture. A bar sounds like a bar, a train platform has its announcements, and a line in quotes is spoken on the right mouth.

Prompts that worked on Seedance 2.5

Real outputs with the exact prompt we used, and why it worked. Hit Recreate to try the same settings.

A woman in a long black gown stands on a rain-soaked plaza at night with her fist raised, millions of glass shards and raindrops hanging frozen in the air around her — Time is frozen: the rain and the wall of shattered glass hang dead still for a beat. Then the camera charges in fast and whips around her as she closes her raised hand into a fist; the suspended shards snap into a spiralling orbit around her, the frozen raindrops streak into long lines, and the whole shockwave blasts outward past the lens as the rain crashes down all at once. Her gown and hair whip in the blast. Extreme camera move, anamorphic flares, cold blue-white grade, shattering glass and a deep low boom.
The prompt is written as a timeline: first everything freezes, then the camera charges in. Ordering the beats like that is what gets Seedance to hold a pause and then release it.
Recreate

A wide, low shot of an empty indoor pool at night lit from underwater as a single swimmer glides along a lane — Follow the camera language of the reference clip — low, wide, drifting right — but stage it in an empty indoor pool at night. Cut the movement to the pulse in the reference track. One swimmer, underwater lights, tiles echoing.
Instead of describing camera moves in words, it points at a reference clip and asks for its camera language in a new location. That is the reference mode at its most useful.

How to prompt Seedance 2.5

Write the shot, not the picture: subject, action, camera, light, then sound, one idea per sentence.
Already have a still you like? Use it as the first frame. The look stays put and the prompt only has to describe the motion.
Draft at 480p and five seconds, then rerun the keeper at 1080p. A single take starts to drift past about ten seconds, so shorter takes cut together usually look better.

Settings worth knowing

Everything else has a sensible default, so you can type a prompt and go.

resolution480p · 720p · 1080p: Output size. Bigger sizes look sharper and cost more.
aspect_ratio21:9 · 16:9 · 4:3 · 1:1 · 3:4 · 9:16: The shape of the frame: wide, square or tall.
duration_seconds4–30s: How long the clip runs. You pay per second.
generate_audio: Adds sound made to match the picture: voices, ambience and effects.
reference_image_urls≤ 30: Pictures of the people, outfits or places the result should keep.
image_url: The picture to start from.
last_image_url: Optional final frame, so the clip ends exactly where you want.
reference_video_urls≤ 10: Clips whose motion, camera or style the result should follow.
reference_audio_urls≤ 10: Audio to match: a voice, music or a rhythm.

Where Seedance 2.5 falls short

It is the slowest model in the catalog: plan for several minutes per clip, more at 1080p and 30 seconds.
It is also one of the pricier per second. Draft at 480p and five seconds before committing to a long 1080p take.
Past about ten seconds, faces and backgrounds can drift. Several shorter takes often cut together better than one long one.

Why is Seedance 2.5 slower than other models?

It renders longer, higher detail takes with sound in one pass. Expect a few minutes for a five second clip and longer for 30 seconds at 1080p; you can leave the page and the result waits in your library.
