Free Seedance 2.5 AI Video Generator
Four Seedance 2.5 runs, thirty seconds each
Every clip below is a single generation running the full thirty seconds — no cuts, no stitching, no second pass. What to watch is not the spectacle but what stays put across half a minute: the same face, the same wardrobe, the same room, the same light.
Identity across shot changes
What is Seedance 2.5?
Seedance 2.5 is ByteDance's newest video model and the first tier here that generates a full scene in one pass. The Seedance 2 tiers are shot machines: describe a moment, get four to ten seconds of it, and anything longer becomes a stitching problem — matching light, matching wardrobe, matching the way a character walks, across clips that were never told about each other.
Most of the effort in AI video today goes into hiding that seam. Thirty seconds in a single generation removes it instead. The second change is what you are allowed to hand the model. One request takes up to ten reference images at once — the character from three angles, the product, the set, the colour key — so the look is handed over instead of squeezed into one sentence of prompt, and the prompt is left free to say what happens.
Seedance 2.5 runs at 480p, 720p or 1080p in seven aspect ratios, billed per second, with generated audio as a switch rather than a separate job.

What a clip costs
The Seedance 2.5 rate is per second and depends on the resolution you pick.
One take, up to 30 seconds
Pick 5, 10, 15, 20 or the full 30 seconds, and every length is a single Seedance 2.5 generation.
Ten reference images
Not one still but a whole reference board, read in the same request.
Sound in the same run
Switch on generated audio and the track comes out with the picture.
When Seedance 2.5 is the right pick
Pick Seedance 2.5 when the thing you need is longer than a shot, or when you already own the look. A thirty-second take that holds one character is worth more than four eight-second takes that nearly do, because the near-misses cost you an edit and usually a re-run. The same goes for references: if you have character sheets, a product photo or a colour key, handing them over as reference images is more reliable than describing them and hoping. Choose Seedance 2.5 for the take you intend to keep: give it the look as references, then carry the whole scene through one generation. The prompt transfers up.
Scenes, not shots
One generation covers a beginning, a middle and an end, so there is no seam to hide.
You already have the look
Reference images carry identity and look far more reliably than adjectives do.
Test at 480p, finish at 1080p
All three tiers run Seedance 2.5, so find the shot on the cheap one and spend on the take you keep.
Seedance 2.5 features
What Seedance 2.5 accepts, and what comes out the other side.
5 to 30 seconds
5, 10, 15, 20 or 30 seconds, each one a single Seedance 2.5 generation.
Up to ten reference images
Character sheets, product shots or colour keys, all in the same Seedance 2.5 request.
Billed by the second
Credits scale with the seconds you run, so a five-second test costs a sixth of the full take.
Generated audio
Sound produced with the picture, as a switch on the request rather than a second job.
Seven aspect ratios
1:1, 4:3, 3:4, 16:9, 9:16, 21:9 or adaptive — vertical comes straight out of Seedance 2.5.
Start from your own images
Upload up to ten stills and Seedance 2.5 builds the moving scene around them.

Getting thirty Seedance 2.5 seconds that hold together
Long Seedance 2.5 generations reward different habits than short ones.
Write beats, not one sentence
A five-second prompt describes a moment; a thirty-second prompt has to describe an order — what happens first, what the camera does when it changes, where it ends.
Put the look in the references
Character, product and colour key go in as reference images; the prompt carries the action. Prompts go vague when they carry both.
Prove it at five seconds
Same prompt, same references, short duration. Seedance 2.5 is priced per second, so a test costs a sixth of the take.
Then commit to the length
Once the look is locked, re-run long. The full take is the deliverable; the short one was the rehearsal.
What a thirty-second Seedance 2.5 take is for
Jobs where the length and the references are the point.
A spot with a beginning and an end
Setup, turn and payoff inside one generation, rather than three clips and an edit.
One character across a scene
Reference images hold identity for the full take, which is what short clips keep breaking.
A product that stays on-model
Product shots as references keep the shape, label and colour fixed for all thirty seconds.
A spot with its sound
Generated audio comes out with the picture, so the take is finished when the run is.

Seedance 2.5 FAQ
Answered from the published schema and our own runs.
Two things. Length: Seedance 2.5 generates up to 30 seconds in a single call, where the 2.0 tiers top out well short of that. References: 2.5 reads up to ten reference images in one request, so a character, a product and a colour key all go in together instead of being described in the prompt. The 2.0 tiers stay on the site because they are cheaper per second and still suit short work.
Yes — one request, one output file, no stitching on our side. That is the whole point of Seedance 2.5, and it is why the examples on this page are all exactly thirty seconds rather than a montage.
480p, 720p or 1080p, in 1:1, 4:3, 3:4, 16:9, 9:16, 21:9 or adaptive, as mp4. Vertical 9:16 comes straight out of Seedance 2.5, so a social cut needs no reframing afterwards. 1080p is the delivery tier: same model, same references, more detail held through a long take.
Reference images set identity and look, and Seedance 2.5 holds them across the full take — that is what makes a thirty-second shot of the same character possible. Use up to ten: the character from several angles, the product, the setting, a colour key. Then keep the prompt for what happens and in what order — the images already carry what it looks like.
Per second, with the estimate shown before you run it. A 5-second clip is about 525 credits at 480p, 1,185 at 720p and 2,970 at 1080p; a full 30-second take is about 3,150, 7,090 and 17,815. The sensible workflow is the cheap one: test the idea at five seconds, then commit to the full length once the shot is right.
Long takes amplify a vague prompt. At five seconds an underspecified prompt simply picks something; at thirty it has time to drift — the camera wanders, or the scene resolves into a different one than you had in mind. The fix is sequence: say what happens in what order. Reference images tighten identity considerably, but they do not substitute for telling Seedance 2.5 where the shot is going.
The Seedance 2.5 tier holds a single take up to 30 seconds, so anything story-length starts here, with generated audio available in the same run. For a short clip with sound in one pass, Veo 3.1 is built for that.
