Seedance 2.5 AI Video Generator

Seedance 2.5 is the video model ByteDance released on 31 July 2026. It turns a written scene or photos into a clip with sound, and it is built for scenes with several shots and short dialogue inside one render. On CastTake you pick it in the studio, choose a length of 5, 8, 10 or 15 seconds at 720p, and see the credit price before you press Generate. We rendered our own test clips with it on 16 and 17 October 2026 and show every clip we could save on this page with its prompt, including two prompts also run through MiniMax H3 for a side-by-side.

No, not on CastTake, and it is the priciest video model we sell. Sign-in credits do not cover video renders: your first credit pack opens every video model, and pack credits never expire. A 5-second 720p clip costs 325 credits. If you are still finding the idea, draft it on MiniMax H3 at 10 credits a clip, then spend on Seedance 2.5 once the scene needs several shots or a conversation in one render. Copy one of the prompts on this page so your first paid clip starts from something that already worked.

On CastTake it costs 325 credits for 5 seconds, 650 for 10 seconds and 975 for 15 seconds, all at 720p. Text, photo and reference-photo clips cost the same. The studio shows the exact total on the Generate button before anything renders, and nothing is charged until you press it. If a render fails, the credits come back. Credits come from a plan or a top-up pack on the pricing page, and every other model's price is on the models page.

ByteDance offers Seedance 2.5 to developers through its own cloud platform, with keys, quotas and pricing set there. CastTake does not resell API access. What we offer is the finished tool: write the scene, add photos if you want, see the price and download the MP4. If you need clips rather than an integration, that saves writing code and managing keys, and every finished video stays in your account history to download again later, with the prompt you used kept beside it.

Use MiniMax H3 for single shots and lots of tries, and Seedance 2.5 when one clip has to hold several shots or a two-person exchange. On CastTake H3 costs 10 credits for 5 seconds at 720p and Seedance 2.5 costs 325, so you can make many H3 drafts for the price of one Seedance clip. H3 also renders 1080p, while Seedance 2.5 is sold at 720p here. Our two matched prompts below show how they differ on the same words: in one run each, Seedance spoke the bus stop line exactly where H3 doubled a word, and drew a real puppy where H3 drew a grown dog.

Start with how many shots you want, then describe each one on its own: "Three shots. Shot 1: ... Shot 2: ... Shot 3: ...". Give each shot one subject and one action, because in a 5-second clip each shot only lasts a second or two. Put spoken lines in quotation marks and say who speaks them. Finish with the sound you want, such as waves, music or a crowd. Keep away from real people, brands and well-known characters, since prompts that resemble them can be refused, at no charge but some waiting.
