Seedance 2.5 is a multimodal AI video generator that can turn prompts, images, and reference clips into finished videos with native audio. According to official information, it supports generating cinematic shots at up to 4K quality, can maintain visual consistency across multiple scenes, and can generate videos up to 30 seconds long based on a single creative brief.
Key capabilities
-
4K video and native audio: Generate detailed videos at up to 4K, while simultaneously generating dialogue, ambient sound, music, and sound effects on the same timeline, with picture and sound output together as a single result.
-
Multiple starting methods: You can write new scenes from scratch from a text prompt, animate a first frame (or first and last frames), or upload reference files so that characters, products, actions, or sounds remain recognizable across multiple shots. Users can choose a mode based on the materials they already have.
-
Coherent motion up to 30 seconds: Keep characters, products, environments, and visual style recognizable from beginning to end in longer shots, carrying the creative direction through to a video of up to about 30 seconds.
-
Precise creative control: Shape transitions with first and last frames, modify shots with targeted instructions, and preserve characters, products, composition, and visual style while changing motion, camera direction, or mood.
-
Multimodal references: Seedance 2.5's reference mode accepts up to 30 images, 10 video clips, and 10 audio files; official information states that the lower-priced 2.0 tier has lower limits.
-
Sound completed in the same generation: Seedance generates ambient sound, effects, and dialogue along with the visuals, and audio can be disabled in a single request to obtain a silent result.
How to use
The officially provided generation steps are as follows: Step one, choose a starting point, open with a text prompt, upload a first frame, or add image, video, and audio references, choosing the method that provides the model with the clearest brief. Step two, write one shot, describing the subject, action, camera movement, lighting, and sound in the order in which they occur; each prompt works best as one continuous shot. Step three, set duration and format, choose the duration, aspect ratio, and output settings that meet the project's needs, preview the generation details, and start creating. Step four, review and refine, check motion, coherence, and audio in the preview, then rerun the prompt from history with more precise camera movement or a different tier.
Use cases
Examples shown on the official website that can be created include: demonstrating environmental continuity through a slowly advancing shot through falling snow; testing surface continuity, reflections, and smooth 360-degree camera movement through a controlled product film; and presenting slow-motion color mixing and composition suited to phone screens in vertical format. Overall, it is suitable for needsCinematic shots, character or product consistency, native audio, and video creation for longer single-shot content.
