Features
Seedance 2.5 Features
Cover text-to-video and image-to-video on one page — from a first prompt to a start-and-end-frame clip.
One-Take Clips Up to 30 Seconds
Generate a single clip from 4 to 30 seconds without stitching shorter takes. ByteDance positions Seedance 2.5 for longer single-pass scenes, so you can hold a camera move, a product turn, or a short story beat in one run. Start short while you test the prompt, then raise duration once the motion is right.
Try a 30s promptNative Audio With the Picture
Keep generate-audio on to produce synchronized sound with the video in the same run. Use it for ambience, performance, or a product clip that needs more than a silent loop. Turn it off only when you plan to replace the soundtrack later.
Toggle native audioSix Aspect Ratios for Text-to-Video
Text-to-video supports 16:9, 9:16, 4:3, 3:4, 1:1, and 21:9, defaulting to 16:9. Pick the ratio before you generate so the composition matches the platform — widescreen, vertical, square, or ultrawide. Image-to-video follows the start image instead of a separate ratio control.
See all aspect ratiosImage-to-Video With an Optional Last Frame
Upload a start image to lock subject, composition, and style, then describe the motion. Add a last-frame image when the ending pose or product angle matters. Resolution still goes from 480p to 4K, and duration stays 4 to 30 seconds.
Test image-to-videoHow to use
How to Use Seedance 2.5
Write a director-style prompt, pick duration and resolution, then generate. For image-to-video, add a start frame and an optional last frame.
Describe the Shot
Write the subject, action, camera move, lighting, and mood. Seedance 2.5 follows director-style prompts — include shot size and atmosphere when those details matter.
Choose Length and Resolution
Set duration from 4 to 30 seconds. 480p is the default for cheaper tests; raise to 720p, 1080p, or 4K when the final clip needs to hold up on a large screen.
Start from Text or an Image
Stay on text-to-video to invent the frame, or switch to image-to-video and upload a start image. Add a second image when you want the clip to land on a specific last frame. Text-to-video uses one of 6 aspect ratios; image-to-video follows the start image.
Generate and Review
Keep native audio on when the clip needs synchronized sound. Credits are shown before each run — start at 480p and a short duration, then raise resolution once the motion is right.
Who it's for
Who Should Use Seedance 2.5
Teams and creators who need longer single-pass clips with optional native audio.
Filmmakers & Directors
Block a 10–30 second scene with camera moves, lighting notes, and performance direction in the prompt. Use 720p to iterate, then render 1080p or 4K when the take is worth keeping.
Marketing & Ad Teams
Turn a still keyframe into a short commercial beat, or write a text-to-video prompt for a product scene. Native audio keeps the first pass usable as a pitch clip before a sound mix.
E-commerce & Product Photographers
Animate a product photo into a turntable or lifestyle move. Add a last frame when the ending pack shot has to match a specific angle, and keep the start image as the identity lock.
Social & Short-Form Creators
Generate 9:16 or 1:1 clips from a prompt, or animate a still for Reels and Shorts. Start at 480p or 720p so you can test several hooks before spending on a longer 1080p cut.
Concept & Storyboard Teams
Preview a scene at 4–8 seconds, then extend duration once the blocking works. Director-style prompts let you specify shot size, camera path, and mood without a separate animatic tool.
Production & Post Teams
Use 1080p or 4K when the clip has to sit next to live-action plates. Credits scale with duration and resolution, so keep early reviews at 480p or 720p.
