Seedance 2.5 guide
Everything you can do with Seedance 2.5
Seedance 2.5 is ByteDance’s video generation model, available in the Krea 3 studio alongside Seedance 2.0 and Seedance 2.0 Fast. It is the pick when you need longer clips, many reference images, and synchronized sound in one generation. This guide explains what each input does and how to get a usable clip on the first few tries.
What Seedance 2.5 is built for
Seedance 2.5 handles three jobs: text to video, image to video from a first frame, and reference to video. In text mode you describe the shot. In image mode you supply the opening frame and describe how it moves. In reference mode you supply up to 30 reference images, so the model keeps a character, outfit, or visual style steady across the clip.
Clips run from 4 to 30 seconds at 480p or 720p, which makes the model unusually good for scenes that need time to develop rather than a single looping gesture. An Audio toggle adds synchronized sound generated together with the picture, so you are not left matching a soundtrack afterwards.
Long clips
Durations from 4 to 30 seconds let a single generation carry an establishing shot, an action, and a payoff.
Many references
Up to 30 reference images hold identity and style, which is the difference between one lucky clip and a repeatable character.
Flexible framing
Choose 16:9, 9:16, 1:1, 4:3, 3:4, 21:9, or adaptive to match the source image.
Writing a Seedance 2.5 video prompt
Think in shots, not in sentences. A good video prompt states the subject, the action, the camera, and the light: "A courier cycles through a rainy neon street at night, low tracking shot following from behind, reflections on wet asphalt, handheld feel". Camera language such as tracking, dolly, orbit, or static wide changes the result more than extra adjectives do.
Describe one clear action per clip. If you need three beats, give them in order: "she opens the door, steps outside, looks up at the sky". When audio is on, mention the sounds you want, such as rain, footsteps, or distant traffic, so the generated track matches the scene.
Using first frames and references
For brand or character work, start from an image. Generate a still with Krea 3 or Seedream 5 Pro in the same studio, send it to Seedance 2.5 as the first frame, and describe the motion. This two-step route gives you control over the look before you spend credits on motion.
In reference mode, use clean images with a single subject and consistent lighting. Label what each reference is for in the prompt. A mix of one face reference, one wardrobe reference, and one location reference works better than thirty near-identical portraits. First-frame mode and reference mode cannot be combined in one run, so pick the one that fits the shot.
Seedance 2.5 compared with other video models
Choose Seedance 2.5 for length and references. Choose Seedance 2.0 when 15 seconds is enough and you want a 4K option, or Seedance 2.0 Fast for quick drafts. Because every tier is in the same studio, you can run the same idea through two engines and keep the better take.
Cost and workflow tips
Seedance 2.5 bills per second, and the studio shows the exact credit estimate before you generate. Draft at 480p and a short duration to test the idea, then re-run the keeper at 720p or 1080p and full length. Failed generations are refunded automatically, and paid plans include commercial usage rights for finished clips.
