Image, video and audio as references — combine all three, not just one image.
Native audio
Sound generated alongside the picture — rain, footsteps and wind line up with what's on screen.
Continuous duration
Pick any length from 4 to 15 seconds — not fixed buckets — to fit your shot's pacing.
First / last frame control
Pin both ends of a shot and Seedance 2 fills the motion. Fast and stable for motion graphics.
What is Seedance 2?
Seedance 2 is the second-generation video model from ByteDance's Doubao team — the same lab that put Chinese video models back on the front bench with Seedance 1.x in 2024. Seedance 2 commits hard on two fronts: native audio (sound is generated together with the picture, no separate sound-design pass), and multi-modal reference inputs (you can hand it a reference image, a reference video and even a reference audio clip at the same time and have the model honour all three). It accepts plain text prompts, first/last-frame anchoring, and combined-asset references.
Duration is continuous from 4 to 15 seconds (not fixed buckets), up to 1080p, with native aspect ratios for landscape, vertical and square. Compared with the Fast variant in the same family, the full Seedance 2 has a higher quality ceiling and finer motion, making it the pick for final shots; the Fast variant still supports 4–15s and native audio but caps at 720p, with a lower per-second rate — better for high-volume iteration or running content matrices. You can switch between the two without rewriting the prompt.
This Seedance 2 video generator is also one of the engines inside the full Story Into Video workflow — pick Seedance 2 as your engine, write a script, and the workflow chains multiple Seedance 2 shots together with locked characters, AI narration and subtitles. Pricing, duration limits and quality tiers are read live from the platform so the Seedance 2 cost on the generate button always matches what you actually pay.
What people use Seedance 2 for
Three flows where the multi-modal reference power shines.
Style-referenced derivative shots from existing video
Most other models only read images. Seedance 2 can read video — hand it a clip whose camera language or color grade you love, then write a one-liner for a new scene, and the output keeps the source's rhythm and palette. Ideal for style-consistent series, or batch-producing shots inside a locked brand look.
Frame-pinned product or logo motion graphics
Lock a first frame (product on a table) and a last frame (logo centered), and Seedance 2 fills the transition plus the ambient audio. Shots like this used to mean two passes — motion graphics and a sound designer — now they take one prompt and two stills. The output is native 1080p, ready for a landing page or paid social ad.
Vertical short-form storytelling with built-in audio
TikTok, Reels and Xiaohongshu favour 5–8 second cinematic cuts. Seedance 2 in 9:16 with native audio produces a finished-feeling clip out of the box — rain, wind, footsteps lined up with what's on screen. No separate audio mix step before posting.
How it works
Three steps from idea to shareable clip — no editor, no plugins.
01 · Write
Write one prompt
Describe the shot in plain language. Include subject, action, lighting and camera move. The longer the better — modern models reward detail.
02 · Pick
Pick mode + duration
Switch between Text, Image-to-Video, or First / Last frame. Pick the resolution and length you want — the price updates live as you choose.
03 · Generate
Generate, download, iterate
Hit Generate and your clip lands in the library within minutes. Save it, remix the prompt, or chain it into a full multi-shot story in the Story Into Video workflow.
Use the Seedance 2 video generator inside Story Into Video
This tool page gives you one Seedance 2 clip per click — 4 to 15 seconds, audio included. If you only need a single shot, this is enough. But the real value of Story Into Video is stitching multiple shots into a full story with consistent characters, scene transitions, AI narration and subtitles.
Inside the full workflow, Seedance 2 stays available as your video engine, but now: characters lock across shots, prompts are auto-generated from your script, and the audio Seedance 2 produces is mixed with AI narration and subtitles into a single export-ready video. Use this page to test a single prompt; switch to the workflow when you're ready to ship a 1–3 minute story.
