SeeDance 2.5 — AI video generation and editing with references
SeeDance 2.5 is a multimodal AI model for creating and transforming video. Give it text, images, video clips, and audio, then combine those materials into a 4-to-30-second sequence. It is not limited to generating from scratch: the model can extend footage, follow motion and style references, connect a first frame to a last frame, and generate sound together with the picture.
What SeeDance 2.5 can do
A single request can contain up to 30 images, 10 videos, and 10 audio files. Images anchor a character, product, or location; videos demonstrate movement, editing rhythm, or camera work; audio supplies speech, music, or atmosphere. Your written prompt tells the model what role each asset plays and describes the final action you want to see.
This combination works well for commercials, music clips, short stories, and extensions of existing footage. Instead of explaining everything in a long paragraph, you can show the model a face, a product, a camera move, and a soundtrack. SeeDance 2.5 interprets them as one brief and preserves specific details more reliably than a generator that sees only text or one opening image.
First and last frames versus reference mode
In first-and-last-frame mode, upload the composition where the shot should begin and the one where it should end. The model creates the motion between them. This is useful for transformations, object reveals, time-of-day changes, and transitions. Keep the characters and geometry reasonably compatible; an abrupt change of space forces the model to invent too many intermediate events.
Reference mode is better when identity, a product, visual style, or movement matters most. Mention uploaded assets as @Image1, @Video1, and @Audio1; their order is displayed beside the uploader. Give every reference one clear job. Explicitly saying what to borrow from each file reduces accidental mixtures of wardrobe, background, movement, and subject.
Video input, sound, web search, and the final frame
SeeDance 2.5 can extend or reinterpret an uploaded clip. Video references may total up to 30 seconds, so trim them to the useful moment. Ask the model to preserve direction, replace the environment, introduce an object, or continue the action after the source ends. When video is used as input, pricing includes both the generated duration and the duration of the supplied video.
Generate audio creates a soundtrack together with the video. Return last frame also provides a still of the closing shot, ready to become the first frame of another generation. Web search can supply current context when a story genuinely depends on it. For a fictional visual scene, leave it off and spend that attention on precise references, composition, and camera direction.
How to write a controllable prompt
Start with the action: who is in the shot, what happens, and how it ends. Add the location, lighting, mood, and visual treatment. Then direct the camera with terms such as wide shot, close-up, locked camera, pan, push-in, or tracking shot. Finish with constraints: which details must not change and which uploaded reference supplies each one.
For a multi-beat clip, use a simple timeline: “0–4 seconds — the character enters; 4–8 — picks up the object; 8–12 — camera pushes closer.” Do not pack a long plot into four seconds, because impossible pacing produces jumps. A practical workflow is to test composition and motion with a short 480p draft, revise the prompt, and render the selected version in 720p.
Formats, duration, and useful workflows
NeuralSpace offers durations from 4 to 30 seconds, 480p and 720p resolution, multiple aspect ratios, and MP4 or MOV output. Vertical framing suits Reels, Shorts, and TikTok; landscape suits advertising and presentations; square works in feeds and product cards. The estimated charge appears before generation and changes with duration, resolution, and the length of video references.
Strong use cases include product videos made from still photos, a consistent hero across a content series, animated storyboards, extensions of existing clips, and scenes synchronized to music or speech. Results remain in your NeuralSpace history. Reuse a successful prompt with new references, or feed the returned final frame into the next request to build a longer connected sequence.
Frequently asked questions
Can SeeDance 2.5 generate video from text alone?
Yes. References are optional, but images, video, and audio give you more control when a particular person, product, motion, or rhythm must be preserved.
How is SeeDance 2.5 different from SeeDance 2.0?
The 2.5 workflow on this page supports clips up to 30 seconds, up to 30 images, 10 videos and 10 audio files, generated sound, a returned last frame, web search, and MP4 or MOV output.
Which resolution should I choose?
Use 480p for faster, less expensive drafts. Choose 720p for the final render after you have confirmed the movement, composition, and prompt.
Can I extend an existing video?
Yes. Upload it as a video reference and describe the continuation clearly. All input video references combined must be no longer than 30 seconds.
