What is Seedance 2.0 and who built it?

Seedance 2.0 is ByteDance's video generation family — three live models that shoot 4–15 second takes from text, an image or mixed references, with voice, sound effects and lip-synced dialogue generated together with the picture. Seedance 2.0 Standard is the flagship and the only tier that reaches 4K (in 10-bit H.265); Seedance 2.0 Fast trades a little fidelity for speed and price; Seedance 2.0 Mini is an independent lightweight model built for volume.

Seedance 2.0 Fast vs Seedance 2.0 Mini — which should I pick?

Fast is the quicker, cheaper cut of the Standard look — 9 credits/s at 480P and 20 at 720P — the right pick when you are iterating on a shot you will finish on Standard. Mini is a separate lightweight model, not a speed preset: at 6 credits/s in 480P and 12 in 720P it is the cheapest way to generate in volume — batches, drafts and social output. Both share the same three modes and reference system; when a shot needs 1080P or 4K, step up to Seedance 2.0 Standard.

How long can Seedance 2.0 videos be?

Any length from 4 to 15 seconds on a continuous slider, billed per second — the same range across Standard, Fast and Mini. Need more? The Seedance 2.0 Extend model continues a finished clip past its last frame, adding 4–15 new seconds per pass.

What reference inputs does Seedance 2.0 accept?

Reference-to-video accepts up to 9 images, 3 video clips and 3 audio tracks per request — characters, products, actions, camera moves and soundtracks, cited by number in the prompt. The samples on this page show the range: an action transferred from one clip into a jewelry concept, a camera extracted from three photos into a turntable shot, and three clips chained into one continuous take.

Does Seedance 2.0 generate audio?

Yes — voice, sound effects and music generate together with the picture, and spoken dialogue lip-syncs with automatic subtitles at the bottom of the frame. Play the office sample above: two characters trade lines in one pass, every word on the lips. Audio can be toggled off whenever you want a silent plate.

Does Seedance 2.0 support 4K?

Yes — on the Standard model only, at 135 credits per second, with output encoded in 10-bit H.265. That codec keeps gradients and grain clean at high resolution, but some older players and editing tools may need a transcode — if a 4K file won't open, play it in VLC or convert it once. Fast and Mini top out at 720P.

How many credits does a Seedance 2.0 video cost?

Billing is per second and per model. At 720P: Seedance 2.0 costs 28 credits/s, Fast 20 and Mini 12. In practice a 5-second 720P clip is 140 credits on Standard, 100 on Fast and 60 on Mini; a 5-second 4K take on Standard is 675 credits. Failed generations are refunded automatically.

How do I write good prompts for Seedance 2.0?

Start from the core formula — subject + motion first, then layer environment, style, camera language and sound as needed. When you attach materials, direct them by number instead of re-describing them: "following the running form of the horse in Video 1", "replace the perfume in Video 1 with the face cream from Image 1". Put dialogue in quotes to get lip-synced delivery with subtitles, and name the sounds you want to hear. Every sample on this page ships its full prompt — hit Remix to start from one; the complete playbook lives in our Seedance 2.0 prompt guide.

Can Seedance 2.0 edit or extend an existing video?

Yes — both are live on Molyin as companion models in the same dropdown. Pick Seedance 2.0 Video Edit to rewrite a 3–15 second source clip from a single instruction — the cream-swap sample above is exactly that — at 22 credits/s in 480P and 47 at 720P, billed on the source length. Pick Seedance 2.0 Extend to continue a clip past its last frame, at 11/24 credits/s billed on the new seconds plus the source seconds.

Does Seedance 2.0 support a seed parameter?

Not yet — Seedance 2.0 does not currently expose a seed, so we keep the control hidden rather than show a field that silently does nothing. For repeatability, keep your prompt, references and settings identical and rerun; the moment seed support ships, the control appears here automatically.

Can I use Seedance 2.0 on Molyin?

Yes — right now, no waitlist. Standard, Fast and Mini are all live in the generator at the top of this page, alongside the Video Edit and Extend companions, on the same credits and workflow as every other model. Start from any sample on this page — hit Remix and the exact prompt and settings land in the generator, ready to make yours.

The two people in the picture are chatting in an office. The woman speaks first, saying: “你每次卡点到，是不是很享受这种刚刚好的感觉？” The man replies with a smile: “我有我的节奏”. As the characters speak, the conversation feels casual and natural, and matching dialogue subtitles appear at the bottom of the frame.

Two images, one clip, one soundtrack — one finished ad

ByteDance's official multimodal reference tutorial. One clip pins the first-person composition, one audio track sets the soundtrack, and two product images anchor the opening and closing frames — the prompt wires them together by number, the way material mentions work in the Molyin generator. Seedance 2.0 reads them as one brief and delivers the commercial.

Video 1 — first-person composition reference

Audio 1 — background music

The prompt

Use the first-person composition of 视频1 throughout, and use 音频1 as the background music throughout. A first-person fruit-tea commercial for the seedance-brand 「苹苹安安」 limited-edition apple fruit tea. The first frame is 图片1: your hand picks a dew-covered Aksu red apple, with a light, crisp knock of apples touching. 2–4s: fast cuts — your hand drops apple chunks into a shaker cup, adds ice and tea base, and shakes hard; the clink of ice and the shaking land right on an upbeat drum groove, background voice: 「鲜切现摇」. 4–6s: first-person close-up of the finished drink — layered fruit tea pours into a clear cup, your hand squeezes a cream top that spreads across the surface, and sticks a pink label onto the cup; the camera pushes in on the layered texture of cream and tea. 6–8s: first-person handheld toast — you raise the fruit tea from 图片2 up to the lens (as if handing it to the viewer), the cup label clearly visible, background voice 「来一口鲜爽」; the final frame freezes on 图片2. All background voices in a consistent female timbre.

The generated commercial — press play to hear the soundtrack. Official ByteDance tutorial sample.

What is Seedance 2.0?

Seedance 2.0 is ByteDance's video generation family and the workhorse line of the Seedance lineup on Molyin. It ships as three live models: Seedance 2.0, the Standard flagship and the only tier that reaches 4K; Seedance 2.0 Fast, a quicker, cheaper cut of the same look; and Seedance 2.0 Mini, an independent lightweight model — not a speed preset — built for high-volume runs at the lowest cost per clip. All three shoot 4–15 second takes from text, an image or mixed references, with voice, sound effects and lip-synced dialogue generated together with the picture.

The reference system is what makes it a daily driver: a single request can carry up to 9 images, 3 video clips and 3 audio tracks — pinning characters and products, borrowing an action from one clip and a camera move from another, all cited by number straight in the prompt. Spoken dialogue lip-syncs with automatic on-screen subtitles, and the family ships two companion models: Seedance 2.0 Video Edit rewrites an existing clip from a single instruction, and Seedance 2.0 Extend continues footage past its last frame.

Seedance 2.0 is in our AI video generator right now — Standard, Fast and Mini in one dropdown, sharing one credit system with the whole lineup, at some of the lowest per-clip Seedance 2.0 prices anywhere.
