What a Seedance 2.5 render costs

Seedance 2.5

From ⚡85. 480p ⚡85 for 4s. 720p ⚡189 for 4s.

Video is paid per render, always. A 4-second 480p draft is ⚡85. The same length at 720p is ⚡189, and 30 seconds at 720p is ⚡1412. New accounts get ⚡50 on signup, which is enough to try the composer and image models, not enough for a full 720p film. $10/1,000⚡ The composer quotes the exact ⚡ before every render, so nothing is charged by surprise.

Frequently asked questions

Open the composer, pick Seedance 2.5, and write your prompt. Set the length anywhere from 4 to 30 seconds, choose 480p or 720p, and pick 16:9, 9:16 or 1:1. Attach your reference stills, clips or audio. The composer shows the exact ⚡ price, then you confirm. Renders land in ~3–4 min and save to your library.

Seedance 2.5 is free to try, and video renders are paid per clip. A new account gets ⚡50 on signup with no card. A Seedance 2.5 take costs more than that grant, so top up when you want the full film. $10/1,000⚡ Image models and short drafts stretch the grant furthest.

No. There's no public checkpoint to download and run on your own machine. Seedance 2.5 is a hosted model, so you reach it through a platform that licenses it. OpenClips is one route: sign in, pick the model in the composer, and render in the browser. Your clips land in one library beside every other model you use.

Renders start at ⚡85 for a 4-second 480p draft. The same length at 720p is ⚡189. A full 30-second take is ⚡636 at 480p and ⚡1412 at 720p. Every step in between has its own price, and the composer shows the exact ⚡ before you confirm. Draft at 480p, then spend on the 720p pass.

Up to 30 seconds in a single take, with 4 seconds as the floor. The composer offers quick picks at 5, 10 and 15 seconds, and you can dial anything in between. ByteDance extends single-pass generation from 15 to 30 seconds. Multi-round extension appends shots to existing outputs, so a story runs past one take.

Yes. Audio is native, made in the same pass as the picture rather than dubbed on later. Dialogue, footsteps and room tone arrive locked to the frames they belong to. You can also attach audio references in the composer, and the model holds them across the take. No separate sound pass, no sync fix afterwards.

Pick 2.5 for length and references, 2.0 for resolution. Seedance 2.5 runs 4–30s in one take at 480p or 720p. Seedance 2.0 caps at 4–15s and renders up to 4K, which matters when the deliverable is a finished spot. Both carry native audio. Drafting on 2.5 and finishing on 2.0 works, since one wallet covers both.

One take. 30 seconds. Sound included.

Write the beats. Attach your references. Render at 720p.

One take instead of a timeline

You write the beats. Seedance 2.5 renders them as one continuous take, 4 to 30 seconds long, with audio made in the same pass. Nothing gets stitched. The cast, the room and the light stay put from first frame to last, because there is no cut to reconcile.

That's the jump from Seedance 2.0. ByteDance extends single-pass generation from 15 to 30 seconds.

References do the art direction

Drop in the look you already have. Feed up to 30 images in one pass. Plus 10 video clips and 10 audio clips. A still pins a face or a package. A clip donates a camera move. An audio bed sets the rhythm. Name each one in the prompt and it holds for the whole take.

Timestamps, not re-rolls

ByteDance added precise editing via timestamps. Write your segments with the action, the framing and the sound for each. After the render, change one stretch and leave the rest untouched. That's the difference between a revision and a fresh roll of the dice.

What OpenClips renders

480p for drafts, 720p for delivery, in 16:9, 9:16 and 1:1. A 4-second 480p draft is ⚡85. Ask for the full 30 seconds at 720p and the composer quotes ⚡1412 before you confirm. When the deliverable needs 4K, that's Seedance 2.0 territory. When you want 1080p fast, use Seedance 1.5 Pro. For silent motion tests on the cheap, there's Seedance 1.0 Pro.
