Seedance 3.0 AI Video Generator
Seedance 3.0 is ByteDance's upcoming AI video model that turns a single prompt into full-length cinematic storytelling. With its Narrative Memory Chain, native emotional dubbing in four languages, and built-in IMAX-grade color presets, the new model takes AI video from 15-second clips to feature-ready scenes—at roughly one-eighth the cost of Seedance 2.0.
Seedance 3.0
ByteDance's next-generation video model is in its closed-door sprint phase—pushing AI video from 15-second clips to full-length cinematic storytelling.
10+ Minute Continuous Stories
A new Narrative Memory Chain keeps characters and scenes consistent across full-length videos—up to 18 minutes in internal tests.
Native Emotional Dubbing
Lip-synced Chinese, English, Japanese, and Korean speech that adjusts breath, laughter, and crying to match each character's emotion.
Cinema-Grade Director Tools
Write a shot-by-shot script with real-time director commands. Built-in IMAX, film-stock, and Netflix color presets for one-click submission.
1/8 the Cost of Seedance 2.0
A minute of cinematic video now costs roughly one-eighth of what Seedance 2.0 needs—built for indie filmmakers and short-drama studios.
Seedance 3.0: From 15-Second Clips to Full-Length Cinema
Seedance 3.0 breaks past every short-clip limit and turns one prompt into a 10-minute movie with synchronized dialogue, multi-shot direction, and cinema color out of the box.
10-Minute Continuous Videos with Narrative Memory
Most AI video models top out around 15 seconds. Seedance 3.0 generates one continuous, coherent video up to 10 minutes long—with 18 minutes reached in internal tests. Its Narrative Memory Chain remembers the story so far: who each character is, what they wore, where the scene is set, and what just happened. The model then plans multi-act structure, foreshadowing, and climactic turns on its own.
Native Emotional Dubbing in Four Languages
Audio is generated together with the video, not added afterward. The model produces naturally lip-synced dialogue in Chinese, English, Japanese, and Korean—and adjusts tone, breathing, laughter, and crying based on what the character is feeling on screen. In closed beta tests, the wuxia-style delivery has been compared to professional voice actors.
Shot-by-Shot Director Control with Color Presets
Write a real storyboard and Seedance 3.0 directs it. Type "Shot 1: wide-angle slow push-in, hero rises from the ruins; Shot 2: fast-cut chase scene with low-frequency drum hits" and the model executes shot by shot. Built-in IMAX, film-stock, and Netflix color presets handle the grade—one click and your scene is submission-ready.
One-Eighth the Cost of Seedance 2.0
A new generation of distillation and efficient inference brings the cost of one minute of cinema-grade video down to roughly one-eighth of what Seedance 2.0 needs—hundreds of times cheaper than shooting a single scene with a real crew. Indie directors, short-drama studios, and advertisers finally get the same toolkit as a major studio.
Plan a Full Scene in 3 Steps
From idea to a cinema-ready video—no editing software, no separate dubbing pass.
Pick a Mode and Set Your Story
Choose between Text-to-Story for prompt-driven generation, Storyboard Director for shot-by-shot control, or Reference-to-Story when you want the model to keep a character or location consistent across the whole video. Pick your duration (up to 10 minutes) and aspect ratio (16:9, 9:16, 21:9, or 1:1).
Configure Audio, Language, and Cinema Look
Pick the dialogue language (English, Chinese, Japanese, or Korean) and let Seedance 3 handle lip-sync and emotional delivery. Choose a color preset—IMAX, film stock, or Netflix—plus 1080p or 4K resolution. Add optional director instructions for camera moves, pacing, and music cues straight in the prompt.
Generate and Export Submission-Ready Video
Seedance 3.0 renders the full scene with synchronized speech, ambient sound, and music in one pass. The output is an MP4 file with the color preset already baked in—ready for YouTube, TikTok, short-drama platforms, or your festival submission with no further editing required.
Why Seedance 3.0 Changes the Game
Four reasons this is the model indie creators and short-drama studios have been waiting for.
🎬 40x Longer Than Most AI Video Models
Most AI video tools cap out at 15 seconds. Seedance 3.0 produces a single coherent 10-minute video—roughly 40 times longer—without the character drift and scene mutation that kill long-form output on every other model.
🧠Narrative Memory Chain Plans the Whole Story
The model remembers plot, character personality, and scene setup across the entire video, then plans multi-act structure, foreshadowing, and climactic turns on its own—so a single prompt produces a story, not a clip.
🗣️ Four-Language Lip Sync with Real Emotion
Dialogue in Chinese, English, Japanese, and Korean is lip-synced and emotionally tuned in the same pass as the video. Sobs, laughter, and breath shift with the character—no separate voice tool or dubbing studio needed.
🎞️ IMAX, Film, and Netflix Color Out of the Box
Seedance 3 ships with industry-standard color grading presets. Pick a preset and the entire scene comes out submission-ready—no separate colorist pass, no LUT hunting, no after-the-fact edit.
đź’° 1/8 the Cost of Seedance 2.0
Thanks to next-generation distillation and faster inference, one minute of cinematic video now costs roughly an eighth of what Seedance 2.0 requires—and hundreds of times less than filming the same scene with a real crew.
đź“ť Storyboard Input Like a Real Director
Write "Shot 1: wide-angle slow push-in; Shot 2: fast-cut chase scene" and Seedance 3.0 directs it shot by shot. The closest thing to a real on-set director that any ByteDance video model has shipped.
Seedance 3.0 FAQ
Common questions about Seedance 3.0—what it does, when it ships, and how it compares to the previous generation.
When will Seedance 3.0 be publicly available?
The model is currently in its closed-door sprint phase with ByteDance's Seed team. There is no official public release date yet; industry observers expect a launch window in late 2026. Join the waitlist on this page and you'll be notified the moment Seedance 3 opens up beyond closed beta.
How long can a single video be?
Seedance 3.0 is designed for long-form output: a single continuous, coherent video can run more than 10 minutes, and internal tests have reached 18 minutes without obvious breakdown. By comparison, Seedance 2.0 generates clips of 4 to 15 seconds—Seedance 3 is roughly 40 times longer in one pass.
What languages will be supported for native dubbing?
The model generates lip-synced native dialogue in Chinese, English, Japanese, and Korean as part of the same video pass. Tone, breathing, laughter, and crying automatically shift to match what the character is doing on screen, so you don't have to layer separate voice-acting or dubbing tools on top.
What resolution and aspect ratios will be supported?
Seedance 3.0 supports up to 4K output and runs in the same wide range of aspect ratios as Seedance 2.0—16:9 and 21:9 for cinematic and YouTube use, 9:16 for vertical short drama and TikTok, plus 1:1 and 4:3 for square and traditional formats. Earlier Seedance 2.0 capped out at 1080p.
How does Seedance 3.0 compare to Seedance 2.0?
Seedance 3 keeps Seedance 2.0's multimodal input (text, image, audio, video reference) but extends almost every limit: clip length jumps from 15 seconds to 10+ minutes, resolution goes from 1080p to 4K, native audio adds real emotional control, a brand-new storyboard director tool ships in the model, and per-minute compute cost falls to roughly one-eighth of Seedance 2.0.
Can generated videos be used commercially?
Yes. The Seedance line is built for indie filmmakers, short-drama studios, advertisers, and brand creators—you'll be able to use the output in commercial work, including ad campaigns, social content, short films, and client projects. Exact commercial terms will be confirmed when the model leaves closed beta sprint.
