输入一个场景，就能得到 4-15 秒视频，对口型对话、音效与音乐都在同一次渲染中生成 — 也可以直接用 Seed Audio 素材库里你自己的参考音频来驱动画面。由 ByteDance Seedance 2.0 提供支持。
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.
参考音频：最多 3 段，wav/mp3，每段 2-15 秒，合计 15 秒，单个文件小于 15MB。
You 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.
一次生成同时渲染画面与对口型对话、音效和音乐 — 是原生音频，不是后期配音。 你下载到的那个 MP4，听起来就已经做完了。 让提示词描述一位夜市厨师正在切菜：刀落下、油声腾起，他的吆喝就落在同一帧上。
最多添加 3 段参考音频 — wav 或 mp3，合计 15 秒 — 可上传，也可取自你的 Seed Audio 历史记录。 第一次渲染，剪切点和动作就落在节拍上。 用提示词描述一段舞蹈，动作便随音乐而动 — 乐句、重音和运镜都踩在节拍上。
你写的对话在生成过程中同时完成配音与口型塑造，整条镜头的对口型都很紧。 你的脚本一次成型，被说出来，落在脸上。 写两句对白，每个角色都用自己的声音准时开口。
每次渲染都可选 480p、720p、1080p 或 4K — 提示词完全不用改。 草稿依然便宜，成片在任何屏幕上依然锐利。
可选 9:16、1:1、4:3、3:4、16:9 或 21:9 — 还有自适应 — 以及 4-15 秒时长。 Shorts 和 Reels 以 9:16 原生构图，绝不中心裁切。 原生渲染 1080x1920 竖屏 — 画面是为信息流而生的，不是硬裁出来的。
用 Seed Audio 的 Prompt Enhance 一键把想法扩写成场景、镜头和音频指示。 不必先学会提示词术语，也能写出细致的提示词。
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.
无需拍摄、录音或配音，就能按日更节奏发布以对话为主的竖屏片段。 你写下台词、生成、发布 — 得到一个 9:16 的 MP4，自带对口型对话和环境声，尺寸适配 TikTok 与 Reels。
把手写脚本或 AI Story Narrator 生成的脚本变成多镜头故事短片，角色始终一致、声音贴合场景，可直接发到 YouTube 或 Reels。 你粘贴脚本里的一个场景，渲染回来的是彼此连贯的镜头 — 同一个角色、场景之间的节奏，以及每个节拍上都在变化的声音。
为一段副歌制作与节拍同步的视觉预告，用于在 Shorts 和 Reels 上预热新歌。 你从 Seed Audio 历史记录里挑出 15 秒副歌作为参考音频，画面就跟着你的节拍切换 — 没有视频预算，也能做发布预告。
制作短广告片段，让产品瞬间与它周围的声音 — 环境声、拟音、人群 — 同时到位，直接可投。 你描述那个产品瞬间 — 手里的罐子、四周欢呼的人群 — 就能得到一个可直接投放的片段，每个声音都对得上它所在的画面。

Get straight answers on the Seedance 2.0 AI video generator — audio, limits, pricing, and how it stacks up.
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.
Seedance 2.0 是 ByteDance 的视频生成模型，它在一次渲染中同时生成画面与原生音频 — 对话、音效、音乐。本页把它做成了在线的 Seedance 2.0 AI 视频生成器：输入提示词，可选添加参考音频，然后下载完成的 MP4。
是的 — 这是 Seedance AI 视频，音频在同一次渲染中生成，而不是事后叠加。口型由对话塑造，环境声贴合场景，音乐与画面一起渲染，所以不需要在剪辑软件里重新对轨。
可以。最多添加 3 段参考音频 — wav 或 mp3，每段 2-15 秒，合计 15 秒，单个文件小于 15MB。你可以上传，也可以直接从 Seed Audio 历史记录里挑一段音轨，画面就会跟着你的声音走。
对话的配音和口型在同一次生成中完成，所以角色说的就是你写的原话，而不是事后配上去的。想要最紧的对口型，请让台词短一些 — 10 秒的片段大约十几个词。
注册免费、无需信用卡，免费方案还包含入门 Credits。视频生成本身消耗 Credits 套餐 — 单个片段的费用按分辨率 × 时长递增，所以 480p 草稿的花费远低于 4K 成片。
分辨率有 480p、720p、1080p 或 4K；画面比例有 1:1、4:3、3:4、16:9、9:16、21:9 或自适应；时长可在 4 到 15 秒之间任选。
什么都不会丢。任务在服务端运行，你回来时生成历史会帮你找回完成的片段；渲染失败会显示重试入口 — 而且绝不会为此重复计费。
在这个生成器里不行 — 它是围绕文本生成视频加可选参考音频设计的。请在提示词里描述你心里那个具体画面（Prompt Enhance 能帮上忙），再用你自己的音频来把控节奏。
已发布的对比强调了 Seedance 2.0 的两个优势：它接受你自己的参考音频作为输入，并且能在一次渲染中生成长达 15 秒、自带原生音频的视频。Kling AI、Google Veo 3 和 Hailuo 也能生成不错的视频，但它们无法让你自己的音轨来驱动画面。
每个工具都基于同一套 Seed Audio 1.0 模型，并共享 315 种声音的声音库。
