Seedance 2.5 AI Video Generator: Up to 30s Clips with Sound
Use Seedance 2.5 on OCMaker AI to turn text or an image into a video with native audio, up to 30 seconds long at 480p or 720p.
Seedance 2.5 is the newest video model in ByteDance’s Seedance family. On OCMaker AI it turns a text prompt or a single image into a clip with its own audio track, and a single generation can run up to 30 seconds — twice as long as Seedance 2.0.
Example clips created on OCMaker AI. Each description includes a prompt idea you can try with Seedance 2.5.
0104
Write the scene as a short shot list — a medium shot, a close-up insert, a wide shot, a reaction — with a rough time for each cut, and keep one main character in every shot. Prompt idea: a hamster in a red scarf whisks batter, pours it into a tiny tin, waits by the oven and proudly holds up the finished cupcake.
0204
Add an image and it becomes the first frame, so your character, outfit and setting stay exactly as they are; the clip keeps the shape of your image. Prompt idea: the florist ties the bouquet, turns toward the camera and offers it with a smile as petals drift through the sunlight.
0304
Every Seedance 2.5 clip comes with a native audio track. Name one sound per beat — a click, a snap, a chime — and describe the room tone underneath. Prompt idea: a watchmaker sets a tiny gear, snaps the case shut, and every clock on the wall strikes the hour at once.
0404
With up to 30 seconds per generation, a whole beginning, middle and end fits in one clip. Give each part of the story its own beat. Prompt idea: an astronaut plants a seedling on a red planet, shields it from a dust storm, and smiles as it unfurls a glowing new leaf.

Seedance 2.5 is already selected in the generator above. Type a prompt for text to video, or add an image to animate it.
Describe what happens beat by beat: the framing of each shot, the action, and one sound for each moment. Longer clips need more beats.
Pick 5, 10, 15 or 30 seconds and 480p or 720p; the credit cost updates as you choose. Download the clip when it is ready.
Seedance 2.5 is the newest video model in ByteDance’s Seedance family. On OCMaker AI you can use it for text-to-video and image-to-video, with a native audio track and clips of up to 30 seconds.
The biggest difference is length: Seedance 2.5 generates up to 30 seconds in one go, while Seedance 2.0 on OCMaker AI stops at 15 seconds. Both run at 480p or 720p here. Seedance 2.5 costs more per second, so 2.0 is still a good choice for short clips.
Yes. Type a prompt without adding an image and Seedance 2.5 generates the whole clip from text, in 9:16 or 16:9.
Yes. Audio is always on and costs nothing extra. Describe the sounds you want in the prompt, ideally one per beat.
Seedance 2.5 is available to members. At 480p a clip costs 27, 54, 80 or 160 credits for 5, 10, 15 or 30 seconds; at 720p it costs 58, 115, 172 or 343 credits.
For short clips, start with Wan 3.0 or Seedance 2.0. Switch to Seedance 2.5 when you need a longer scene of up to 30 seconds in a single generation.
