Seedance 2.5 AI Video Generator

Why Seedance 2.5 stands out

Seedance 2.5 generates a whole shot together with its sound. Footsteps, ambience and music land on the right frames, and dialogue written in quotes gets matching lip movement. It also follows camera language such as dolly-in, rack focus or whip pan more faithfully than most video models.

Length, resolution and format

One run can last anywhere from 4 to 30 seconds, long enough for a complete scene without stitching. Output is 480p or 720p; this route does not offer 1080p. The 480p option costs less than half of the 720p rate. That makes it the cheap way to test a prompt. Pick 9:16 in the form for Reels, TikTok and Shorts.

When to choose another model

For a 1080p master with dialogue, Veo 3.1 renders at a higher resolution and a higher rate. For physical action and object handling without sound, Kling 3.0 is a strong alternative. Both pages are linked in the form.

Start from a still image

This page works from a text prompt. To animate a product photo or a portrait, use the image to video tool, which runs the same model.

Prompting a long take with sound

One run lasts up to 30 seconds, so write a timeline. Cover the start, middle and end, and the sound carrying each part. Quoted dialogue gets lip movement, so name each speaker and give them one short line. For example: "A fruit stall at closing time, the vendor stacks crates and calls 'Last peaches, half price'. Later the shutter rolls down and street noise fades." Or "Two hikers reach a ridge, one says 'We made it before the fog'. The wind rises, the camera pulls back to show the valley." The Talking to camera preset suits spoken lines.

Getting the most from 480p, 720p and 30 seconds

Draft at 480p, about 13 credits per second, to check the action and line timing. Then render the keeper at 720p, 27 credits per second. Durations run from 4 to 30 seconds, so price the take first. At 720p, 10 seconds is 270 credits and 30 seconds is 810 credits. Use 1:1 for feeds, 9:16 for stories, 16:9 for websites. Kling 3.0 at 27 per second gives silent 1080p physical action. MiniMax H3 at 17 per second gives 2K with stereo audio up to 15 seconds. Veo 3.1 at 95 suits a 1080p dialogue master.
