Seedance 2.5 with 30s single-shot output and up to 50 reference assets.
Workflows
Text to Video · Image to Video · First & Last Frame · Reference to Video
Seedance 2.5 lists text-to-video, image-to-video, first-and-last-frame, and reference-to-video workflows. A reference task accepts up to 30 images, 10 video clips, and 10 audio tracks, with 30 seconds of combined reference footage.
Unlike Seedance 2.0, an audio-only reference set is supported — a single track can drive pacing without an accompanying image or clip. The studio validates each asset before submission.
Up to 30 reference images, 10 clips, and 10 audio tracks per task
Audio-only references supported for the first time in the family
First-and-last-frame anchoring with two images
LONGER SINGLE SHOTS
Choose any duration from 4 to 30 seconds
Seedance 2.5 raises the single-shot ceiling from 15 to 30 seconds, with a per-second duration control from 4 through 30. Output resolution is 480p, 720p, or 1080p on this tier.
The route keeps the familiar Seedance ratio set — ultrawide through portrait — and an optional audio toggle. The task quote updates as duration, resolution, and reference footage change.
CHOOSE 2.5 OR 2.0
Match the tier to the output you need
Pick Seedance 2.5 for longer single shots and heavier reference direction. Pick Seedance 2.0 Standard when the task needs 4k output, which stays exclusive to that tier.
Both tiers share the same studio workflows, so a draft can switch between them. Review the live task quote after switching — pricing and available settings differ.
