Choose your starting point
Use image-to-video when the subject already exists in a photo. Choose text-to-video when you want the model to build the whole scene.
Direct one short sequence
Name the subject, then its action, camera movement, and sound. For a longer video, divide the description into timed beats.
Check the cost, then generate
Start with 5 seconds at 720p to check the idea. Increase duration or resolution after the composition and movement work for your project.
A prompt you can adapt
0–3s: A ceramic teapot rests beside a window; steam rises from the spout. 3–7s: The camera moves closer to the glaze while morning light crosses the table. 7–10s: Hold on the teapot. Quiet room tone, no music, no text.

What is Seedance 2.5?
Seedance 2.5 is ByteDance’s audio-video generation model. Use a written scene or a starting image to create a video with camera movement, subject action, and optional sound.
Can Seedance 2.5 generate a 30-second video?
Yes. Select a whole-number duration from 4 to 30 seconds. For a 30-second scene, describe the order of events and avoid repeating the same camera instruction in every sentence.
Does Seedance 2.5 support 1080p and 4K?
Choose 480p, 720p, 1080p, or 4K on Seedancer2. Higher resolution costs more credits. Use the resolution selector above to see the exact cost before submitting.
How much does Seedance 2.5 cost here?
A 5-second video costs 21 credits at 480p, 41 at 720p, 102 at 1080p, or 203 at 4K. The same rates apply to text and single-image input. Disabling audio does not reduce the 2.5 price.
Can I make vertical videos from a landscape photo?
Seedance 2.5 image-to-video follows the input image’s proportions. Crop your image to 9:16 before uploading for a vertical result. In text-to-video, choose 9:16 directly.
Does this tool include Seedance 2.5 video editing and extension?
ByteDance describes editing and extension capabilities in the model family. This tool currently exposes text and single-image generation; video upload, editing, and extension are not available in this form.
