One continuous 30-second take — dialogue, footsteps, and score generated in the same pass as the picture. ByteDance's flagship model is live in this AI video generator: turn text or an image into video with stronger multimodal references (up to 50 inputs), multi-round extensions for longer stories, and lip-synced speech you can direct with plain language.

What this AI video model actually ships — longer takes, joint audio-video, and reference control built for finished stories, not short demos.
One prompt, one continuous half-minute shot — setup, action, and payoff without stitching four clips. Need more runway? Extend the same take across multiple rounds so multi-minute stories keep a consistent audiovisual language.
Dialogue with matched lip-sync, footsteps, engines, ambience, and score — all generated in the same pass as the picture, in multiple languages. Wrap spoken lines in double quotes. Audio never adds a credit surcharge.
Feed the model up to 30 images, 10 video clips, and 10 audio tracks in one generation — faces, wardrobe, products, motion, and even a music bed that can drive pacing. 2.5 reads framing and cinematic intent far more accurately, so characters and looks hold across the full take. This generator sends up to 30 reference images per image-to-video job.
Model budget: 30 images · 10 video · 10 audio. This generator accepts up to 30 reference images per video.
Start an image-to-video generation →Physics, lighting, and emotional intent from plain language — write "slow dolly-in as she realizes" and get the move, the pacing, and the performance. Timestamp-level and region-level edits let you refine one beat without regenerating the whole clip.
Write the move — get pacing, performance, and fine edits without regenerating the whole take.
Real 2.5 video across every format you ship — product ads, short drama, lifestyle, and social — each generated as one continuous 30-second take with sound.
Opening, product moment, end card — a full ad beat in a single 30-second generation instead of three stitched clips. Sound effects land on the action automatically.
Make a Product Ad →Setup, action, payoff — a complete story beat in one unbroken shot. The model holds characters, lighting, and mood steady across the full half-minute.
Shoot a Scene →Golden-hour kitchens, morning routines, travel beats — long enough to breathe, with ambient sound generated alongside the visuals.
Create a Brand Film →9:16, 1:1, 21:9 — six aspect ratios out of the box. Hook, build, payoff in one take, sized for TikTok, Reels, and Shorts.
Make a Vertical Clip →What Seedance 2.5 changes about day-to-day AI video work.
Open the AI Video GeneratorA full beat with setup, action, and payoff in one continuous take — then extend for multi-minute stories without losing the look.
Lip-synced speech, ambience, and effects generated with the video. No silent-clip workflow, no audio surcharge.
Characters, lighting, and scene style stay consistent across the whole half-minute — the hardest problem in long AI video.
30 images + 10 video clips + 10 audio tracks in one generation. Lock faces, products, motion, and music so the look survives the take.
16:9, 9:16, 1:1, 4:3, 3:4, and 21:9 — from cinema widescreen to vertical social, no cropping.
From 280 credits for a 5-second 480p clip, scaling linearly to 30 seconds. What you see is what you spend.
Ads, short films, social, e-commerce — every video ships with dialogue, lip-sync, and score generated in the same pass. Storyboard the full half-minute; extend when you need more runway.
Try a Text-to-Video PromptDrag to browse — steal these structures for your first 30-second take.
Three steps from idea to a finished, sound-on clip.
For text-to-video, write the scene, action, mood, and camera move, and put dialogue in double quotes for lip-sync. For image-to-video, upload reference images to lock the look, character, or product.
Pick Seedance 2.5 in the model menu, then choose resolution (480p or 720p), duration up to 30 seconds, aspect ratio, and keep audio on.
Roll, review, and download the finished video. Storyboard the full 30 seconds (setup → action → payoff). Draft cheap on Mini first if you're iterating prompts.
From solo YouTubers to marketing teams — workflows built around 30-second takes and native sound.
Lip-synced dialogue in the same pass as the picture is the unlock. I storyboard a full 30-second beat, wrap the lines in quotes, and skip hours of audio post.
One 30-second take replaced three stitched clips for our product ads. Characters and lighting hold to the end card — our agency bills dropped overnight.
I lock the cast with reference stills and let 2.5 hold them across the whole take. Mood boards used to be six short clips — now they're one continuous scene with sound.
Hook, build, payoff in one 9:16 generation. This is how I ship 20+ sound-on video ads a week without a production crew.
Straight answers on what 2.5 ships, how it prices, and when to still use Seedance 2.0.

Seedance 2.5 First Test Something feels a little off but I'm not entirely sure what it is. Seedance 2.0 wasn't like this. It seems to morph a bit during fast action scenes. It’s a really expensive model to test, so we'll see how many attempts we can make. Being able to generate Show more
