Seedance 2.0

Seedance 2.0 is ByteDance's flagship cinematic AI video generation model, designed to turn a single text prompt, image, or audio file into a high-quality video clip between 5 and 15 seconds long. What sets it apart is its ability to generate native, synced audio alongside the video in one pass, rather than layering sound on as an afterthought. This means footsteps land on puddles at the exact right frame, raindrops hit umbrellas in rhythm with the audio, and a guitar string vibrates perfectly in sync with the note being played. The model supports phoneme-accurate lip-sync in over eight languages, including English, Mandarin, Japanese, Korean, Spanish, French, and German, making it ideal for character-driven storytelling and dialogue scenes. Seedance 2.0 also gives you director-grade camera control, allowing you to specify complex shots like dolly-ins, rack focuses, Dutch angles, and whip pans, and it will execute them faithfully. With support for 4K resolution and the ability to ingest up to nine images, three videos, and three audio references per generation, it is designed for filmmakers, content creators, marketers, and storytellers who need professional-grade results quickly. The model topped the Artificial Analysis video-generation leaderboard in April 2026 with an Elo score of 1269, outperforming competitors like Google Veo 3, OpenAI Sora 2, and Runway Gen-4.5. You can start with free trial credits upon signing up, and everything runs through the official ByteDance interface.

Native Audio-Video in One Pass

Seedance 2.0 is the first mainstream video model that generates audio and video jointly as a single, coherent output. Instead of creating a silent video and then adding sound effects or music as a separate post-processing step, the model produces frame-accurate audio that matches the visuals from the start. If your prompt describes a person walking through puddles in heavy rain, the splashing sounds will align perfectly with each footstep, and the raindrops hitting an umbrella will sync naturally with the rhythm of the audio. This saves you significant time in post-production and results in a much more immersive viewing experience.

Director-Level Camera Control

You can use cinematic vocabulary in your prompts and Seedance 2.0 will execute those camera movements with precision. Whether you want a slow dolly-in on a character's face, a dramatic rack focus that shifts attention from foreground to background, a Dutch angle for a sense of unease, or a quick whip pan to follow fast action, the model understands and applies these techniques. This allows you to create multi-shot storytelling from a single prompt, so a 15-second render can feel like a carefully edited sequence rather than a single static shot.

Phoneme-Level Lip-Sync in 8+ Languages

When you provide a character portrait and a line of dialogue, Seedance 2.0 animates mouth shapes at the phoneme level rather than the word level. This means the lip movements are precise and natural, matching the specific sounds being spoken rather than just the general cadence of speech. The result holds up under close inspection in English, Mandarin, Japanese, Korean, Spanish, French, German, and more. This makes it ideal for creating talking-head videos, character monologues, interview-style content, and any scenario where realistic speech animation is critical.

Physics That Hold Up Under Scrutiny

The model has been trained on extensive real-world footage, giving it a robust understanding of how objects behave physically. Fabric wrinkles the way cloth should wrinkle when moved. Liquids refract light and splash with realistic surface tension. Particles like dust, smoke, and leaves obey gravity and wind independently from one another. This world model survives slow-motion scrutiny that would expose flaws in other video generators, making Seedance 2.0 a strong choice for scenes requiring realistic material properties and environmental interactions.

Cinematic Short Films and Storytelling

Filmmakers and independent creators can use Seedance 2.0 to produce short, high-quality clips for narratives, mood reels, or concept visualizations. By combining director-level camera control with native audio and realistic physics, you can generate a complete 15-second scene from a single prompt. For example, you could describe a noir-style shot of a detective walking through rain-soaked streets at night, with neon reflections on wet pavement and footsteps synced to the audio, and the model will deliver a polished cinematic clip ready for editing into a larger project.

Marketing and Advertising Content

Marketers can quickly produce professional-grade video ads without needing a full production crew or expensive equipment. Seedance 2.0 allows you to generate product demonstrations, brand stories, or lifestyle scenes with consistent quality and style. You can feed in reference images of your product, a specific location plate, and background music, and the model will fuse them into a coherent render. This is especially useful for social media campaigns where you need multiple variations of an ad in different aspect ratios, such as 16:9 for YouTube and 9:16 for TikTok or Instagram Reels.

Multilingual Talking Head and Interview Videos

Content creators who need to produce videos with characters speaking directly to the camera will benefit from the phoneme-level lip-sync support. You can generate a character portrait, write a script in one of the supported languages, and Seedance 2.0 will animate the mouth shapes accurately. This is ideal for educational videos, news-style reports, character introductions in games, or any project where a virtual presenter needs to deliver lines naturally. The ability to switch between languages also makes it suitable for localization and international content.

Concept Visualization and Pre-Production

Directors, art directors, and game designers can use Seedance 2.0 to visualize concepts before committing to full production. By inputting character sheets, location photos, and reference audio, you can generate a short clip that shows how a scene might look and feel in terms of lighting, camera movement, and physical interactions. This allows you to experiment with different shot compositions, color palettes, and atmospheric effects quickly, saving time and resources during the pre-production phase of larger projects.

How do I get started with Seedance 2.0?

You can start by visiting the official Seedance 2.0 interface and signing up for an account. New users receive free trial credits that allow you to generate a few clips and explore the model's capabilities. After signing in, you can choose between the full-quality Seedance 2.0 model or the faster Seedance 2.0 Fast option, select your desired resolution, duration, and aspect ratio, and then enter a director-style shot description as your prompt. You can also upload images, audio files, or video references to guide the generation.

What languages does the lip-sync feature support?

Seedance 2.0 supports phoneme-accurate lip-sync in over eight languages, including English, Mandarin, Japanese, Korean, Spanish, French, and German. The model animates mouth shapes at the phoneme level, meaning it matches the specific sounds being spoken rather than just the general word cadence. This results in natural and precise lip movements that hold up under close inspection, making it suitable for dialogue-heavy scenes and talking-head videos.

Can I use my own images, videos, or audio as references?

Yes, Seedance 2.0 accepts rich reference payloads. You can feed up to nine images, three videos, and three audio files per generation. This allows you to provide character sheets, location plates, existing footage, or reference music, and the model will fuse them into a single coherent render. Unlike some models that average multiple inputs into a generic result, Seedance 2.0 is designed to preserve the specific details and style of your references.

What resolutions and aspect ratios are available?

Seedance 2.0 supports multiple resolutions, including 480p and 720p standard options, with 4K available for higher quality outputs. You can choose from a variety of aspect ratios to fit different platforms and creative needs: 16:9 for widescreen video, 9:16 for vertical social media content, 1:1 for square formats, 4:3 and 3:4 for more traditional or portrait orientations, and 21:9 for ultra-wide cinematic shots. The duration options are 5 seconds, 10 seconds, and 15 seconds.
