Made With Seedance 2.5
GOOD FOR
Where it Excels
Longest single-shot clips
Generates up to 30 seconds in one pass, so a full beat lands as a single continuous take instead of chained extensions with visible seams.
Dialogue with precise lip sync
Put spoken lines in double quotes and the model generates the audio natively alongside the picture, with mouth movement matched to the delivery.
Multimodal references in one prompt
Mix reference videos, character images and audio in a single request and address each by tag — @Video1 for the source scene, @Image1 for the face, @Audio1 for the timing.
Superior consistency
Faces, clothing, scenes and visual style hold across the whole clip, including over the longer durations where most models drift.
Cinematic action & physics
Complex camera moves, realistic physics and high-budget visual effects, with strong results on stop motion, 2D and 3D animation styles.
TRY TO AVOID
Not Ideal For
Resolutions above 720p
Serves 480p and 720p only. For 1080p or 4K hero work, step up to Seedance 2.0 or a higher-resolution model.
Budget-conscious iteration
The most expensive model per second in the catalogue. Block out ideas on a fast-tier model and switch to 2.5 for the final take.
On-screen text in video frames
Text rendering inside generated frames — signs, labels, UI elements — remains unreliable. Plan titles and captions for post.
Immediate simplicity
References, tags and quoted dialogue reward deliberate prompting; a one-line prompt won't use most of what the model can do.
