Seedance 2.5 AI Video Generator
Create complete audio-video sequences with Seedance 2.5 on Bimg AI. Combine prompts, images, video clips, and audio references to direct longer stories with controlled motion, camera language, timing, and synchronized sound.
Create Longer, More Controlled Videos with Seedance 2.5
Seedance 2.5 brings long-form generation, joint audio-video creation, flexible references, and precise shot direction into one practical AI video workflow.
Up to 30 Seconds in One Generation
Build a complete scene or narrative beat in a single Seedance 2.5 generation. Longer output gives actions, performances, camera moves, and transitions enough time to develop naturally.
Joint Audio-Video Creation
Generate visuals and sound together so dialogue, ambience, effects, and movement feel connected. Turn audio off for silent clips or add audio references to guide rhythm and atmosphere.
Text, Image, Video, and Audio References
Use multimodal references to define characters, products, props, composition, visual style, motion, and sound instead of relying on a text prompt alone.
One-Take Narrative Direction
Plan continuous shots with deliberate subject movement, performance blocking, camera paths, and pacing. Seedance 2.5 is designed to maintain coherence across longer sequences.
Timestamp-Based Prompt Control
Divide a prompt into time ranges such as 0–5s and 5–10s. Specify actions, framing, transitions, dialogue, or sound cues for each segment to guide the sequence more precisely.
More Natural Motion and Transitions
Produce steadier subjects, more realistic movement, and smoother changes between shots. Seedance 2.5 improves continuity while preserving the intended scene and visual identity.
Flexible Creation Modes
Start from text, a first frame, first and last frames, or a mixed reference set. Choose the workflow that fits a storyboard, product shot, social video, or cinematic concept.
Production-Oriented Creative Control
Direct camera perspective, lighting, composition, performance, and green-screen-style scenes through detailed prompts and references for ads, previsualization, education, and product demos.
How to Generate a Video with Seedance 2.5
Turn a creative brief into a synchronized Seedance 2.5 video in three focused steps.
Select Seedance 2.5 and a Creation Mode
Choose text-to-video, first-frame, first-and-last-frame, or multimodal reference mode. Set the aspect ratio, 480p or 720p resolution, and a duration from 1 to 30 seconds.
Write the Timeline and Add References
Describe the subject, action, camera, lighting, sound, and mood. Add images, video, or audio references, and use timestamp ranges when the scene needs precise chronological direction.
Generate, Review, and Download
Generate the video, review motion, timing, continuity, and sound, then refine the prompt or references before downloading the finished MP4.
