03 / Use cases

Where Seedance 2.5 shines.

Dialogue scenes

Write the lines in quotes. The model performs them, lip-synced.

EXAMPLETwo friends argue quietly across a café table — “You knew, didn’t you?” — rack focus between faces, espresso machine hissing.

UGC ad creative

Hook, demo, CTA — a complete vertical ad in one 30-second take.

EXAMPLECreator talks straight to camera about her morning routine, handheld selfie framing, kitchen daylight, natural delivery.

Consistent characters

Lock a face across every shot with up to 30 reference images per run.

EXAMPLEThe red-jacketed courier from the reference set weaves her bike through evening traffic, face steady in every frame.

Music-driven clips

Movement lands on the beat, not near it. Feed it up to 10 reference tracks.

EXAMPLEA dancer hits every beat of the track on a rooftop at blue hour, city bokeh behind, camera locked off.

Previz & blocking

Block with white-models and references, then render the real scene.

EXAMPLEA single steadicam follows two detectives arguing down the precinct corridor, phones ringing behind office doors.

One-take camera moves

Follows, orbits, and slow reveals no 5-second model can hold.

EXAMPLEOne unbroken take: the camera follows a courier through a lantern-lit night market, vendors calling out, rain just ended.

09 / FAQ

Things teams ask.

Q.01What's the $49 offer?
Infer Unlimited: $49/month, all the video and image generation you want in the Studio, Seedance 2.5 included. Free for 24 hours, cancel anytime. API usage is metered separately, per second.
Q.02How long can clips be?
Up to 30 seconds in one shot — the longest single generation of any major model — and you can extend a clip twice.
Q.03Does it really generate audio?
Yes. Dialogue, ambience, and effects generate in the same pass, synced to the picture. Put lines in quotes and they're delivered lip-synced.
Q.04What are reference inputs?
Up to 50 files per request: 30 images to lock identity or style, 10 videos for framing and camera language, 10 audio tracks to steer voice or score.
Q.05What input modes are supported?
Text-to-video, image-to-video from a keyframe, and reference-to-video, which combines your prompt with reference files in one request.
Q.06What resolution is the output?
ByteDance's API launches with 480p and 720p tiers; higher-resolution output has been shown in its own apps. Infer's picker always shows exactly what the live endpoint serves.
Q.07What editing controls does it have?
Region-level edits, green-screen editing, and white-model (3D blocking) control for previz — plus a wider range of audio and visual edit requests than any Seedance before it.
Q.08How do I get the best results?
Prompt like a director: subject, action, setting, one camera move, and the light. Dialogue goes in quotes. Block a 30-second scene beat by beat: Shot 1, Shot 2, Shot 3.
Q.09Can I go longer than 30 seconds?
Yes — extend a generation twice. Framing and subjects stay consistent across the joins.
Q.10Can I use the outputs commercially?
Yes. Same commercial terms as Seedance 2.0 on Infer.
