Seedance 2.0 AI Video

Seedance 2.0 AI Video is an online AI video generation tool based on the Seedance 2.0 multimodal video generation model released by ByteDance in February 2026. According to the official introduction, this model is the first AI video model to simultaneously output synchronized audio and video in a single generation, and it supports real-person videos, multi-shot narratives, and character consistency. Users do not need to install software and can use it through a web page.

In terms of use cases, Seedance 2.0 is aimed at content creators, marketers, and film and television production personnel, and can be used to generate cinematic videos, spokesperson talking-head ads, influencer-style content, product demonstrations, and social media materials, among others.

Main capabilities include:

1. Real-person video generation: Upload a portrait photo as a reference to generate videos with realistic facial expressions, natural micro-expressions, full-body movements (including dancing and sports), and lip-synced dialogue, suitable for spokesperson ads, influencer content, and marketing campaigns centered on faces.
2. Native audio-video generation: Uses dual-channel stereo technology to generate audio and video simultaneously, with sound effects, dialogue, and ambient sound synchronized with on-screen action, eliminating the need for post-production audio work.
3. Multi-shot narrative: Create cinematic multi-shot sequences through a single prompt, using shot-switch keywords to trigger scene transitions, with the model maintaining subject, style, and narrative continuity across shots.
4. Character consistency and video-to-video editing: Uploading a reference photo can lock the face, clothing, and style across all shots, maintaining consistency even through complex camera movement and scene changes; it supports video-to-video editing, allowing specific segments, characters, or actions in an existing video to be modified without regenerating the entire clip.
5. @-reference system: Use markers such as @Image1, @Video1, and @Audio1 in the prompt to tag uploaded files, and the model separately extracts character appearance (from images), camera path (from videos), and beat rhythm (from audio). A single generation can combine up to 9 images, 3 videos, and 3 audio files. The official statement says this capability is not available in Sora 2, Kling, or Veo 3.1.
6. Multilingual lip sync: Supports phoneme-level lip sync in more than 8 languages, including English, Chinese, Japanese, Korean, Spanish, French, German, and Portuguese, suitable for global spokesperson content and multilingual marketing campaigns.

The usage method is divided into four steps:

1. Describe the video: Enter a detailed text prompt including scene description, camera movement, lighting, and audio cues; shot-switch keywords can be used for multi-shot sequences.
2. Upload references (optional): Add reference images, videos, or audio clips for character consistency,visual direction, or sound matching, with support for up to 12 multimodal inputs in a single generation.
3. Generate: Seedance 2.0 processes the prompt and creates a cinematic video with synchronized audio within 30 to 40 seconds, automatically completing multi-shot composition, character consistency, camera movement, and stereo design.
4. Download and share: Preview the finished video at up to 2K resolution, download it in MP4 format, and share it directly to platforms such as YouTube, TikTok, and Instagram; it can be regenerated or optimized, and credits are deducted only when generation is successful.

Applicable scenarios include: text-to-video, image-to-video, video-to-video editing, spokesperson talking-head ads, multilingual marketing campaigns, social media content creation, product demonstrations, and photo animation, among others.

Limitations and notes: The official statement says the average generation speed is 30 to 40 seconds, depending on video length, resolution, and prompt complexity. New users can receive free credits upon registration, enough to generate several AI videos; for higher usage, Lite and Pro subscription plans can be chosen, providing more credits, higher-resolution output, and batch generation, among other features. Details such as specific pricing, credit amounts, output resolution limits, and commercial licensing are not yet provided in the materials.
