Text to video with sound
Describe your shot, set resolution, ratio, and length, and hit generate. Your render arrives with lip-synced dialogue, scene-matched SFX, and music already in place — and a reference audio track from your Seed Audio library can drive the whole thing.
Reference audio: up to 3 clips, wav/mp3, 2-15s each, 15s combined, under 15MB per file.
Adaptive lets the model pick the best frame for your scene.

Start Creating FreeYou get one MP4 per render from this Seedance 2.0 AI video generator — picture and audio born together, no timeline, no overdub, no drift to chase.
One generation pass renders picture plus lip-synced dialogue, sound effects, and music — native audio, not an overdub. You download one MP4 that already sounds finished. Prompt a night-market cook mid-chop: the knife hits, the sizzle swells, and his shout lands on the same frame.
Add up to 3 reference audio clips — wav or mp3, 15 seconds total — from upload or your Seed Audio history. Cuts and motion land on the beat from the first render. Prompt a dance scene and the movement rides the music — phrasing, hits, and camera moves arriving on the beat.
Dialogue you write is voiced and mouth-shaped together during generation, keeping lip sync tight through the take. Your script comes out spoken, on-face, in one go. Write a two-line exchange; each character speaks on cue with its own voice.
Choose 480p, 720p, 1080p, or 4K per render — the prompt stays untouched. Drafts stay cheap; finals stay sharp on any screen.
Pick 9:16, 1:1, 4:3, 3:4, 16:9, or 21:9 — plus adaptive — and 4-15 second duration. Shorts and Reels composed natively at 9:16, never center-cropped. Render a 1080x1920 vertical natively — the frame is built for the feed, not trimmed down to fit it.
One click expands your idea into scene, camera, and audio directions with Seed Audio's Prompt Enhance. Detailed prompts without learning prompt-speak first.
Whether you're a short-form creator, storyteller, musician, or marketer — audio driven video generation fits wherever sound sells the shot.
Publish dialogue-driven vertical clips on a daily cadence without filming, recording, or dubbing audio. You write the line, generate, and post — a 9:16 MP4 with lip-synced dialogue and room tone, sized for TikTok and Reels.
Turn a written or AI Story Narrator script into a multi-shot story short with one consistent character and scene-matched sound, ready for YouTube or Reels. You paste a scene from your script and the render comes back as connected shots — one character, scene-to-scene pacing, sound that shifts on every beat.
Create a beat-synced visual teaser for a track hook to tease a release on Shorts and Reels. You pick a 15-second hook from your Seed Audio history as reference audio and the visuals cut on your beat — a release teaser without a video budget.
Produce short ad clips where the product moment and the sound around it — ambience, foley, crowd — arrive together, ad-ready. You describe the product moment — the can in hand, the crowd roaring around it — and get an ad-ready clip where every sound matches its frame.

Seedance 2.0 is ByteDance's video generation model that renders picture and native audio — dialogue, sound effects, music — together in a single pass. This page runs it as an online Seedance 2.0 AI video generator: type a prompt, optionally add reference audio, download a finished MP4.
Yes — this is Seedance AI video with audio generated in the same pass, not layered on afterward. Lip movement is shaped by the dialogue, ambience matches the scene, and music renders with the picture, so nothing needs re-syncing in an editor.
Yes. Add up to 3 reference audio clips — wav or mp3, 2-15 seconds each, 15 seconds combined, under 15MB per file. Upload them or pick a track straight from your Seed Audio history, and the visuals follow your sound.
Dialogue is voiced and mouth-shaped in the same generation, so characters speak your exact words instead of getting dubbed after. For the tightest lip sync, keep spoken lines short — around a dozen words for a 10-second clip.
Signing up is free, needs no credit card, and the free plan includes starter credits. Video generation itself runs on credit packs — a clip's cost scales with resolution × duration, so 480p drafts cost far less than 4K finals.
Resolutions of 480p, 720p, 1080p, or 4K; aspect ratios 1:1, 4:3, 3:4, 16:9, 9:16, 21:9, or adaptive; and any duration from 4 to 15 seconds.
Nothing is lost. Jobs run server-side, your generation history restores the finished clip when you return, and a failed render shows a retry — you're never double-charged for it.
Not in this generator — it's built around text to video with optional reference audio. Describe the exact frame you have in mind in the prompt (Prompt Enhance helps), and drive pacing with your own audio.
Published comparisons highlight two Seedance 2.0 advantages: it accepts your own reference audio as an input, and it renders up to 15 seconds with native audio in one pass. Kling AI, Google Veo 3, and Hailuo generate strong video, but they don't let your own track drive the picture.
Every tool runs on the same Seed Audio 1.0 model and 315-voice library.
