Seedance 2.0 is an AI video generator by ByteDance that turns text, images, audio, or video inputs into broadcast-ready 2K videos with native voiceover and lip sync in under 60 seconds — replacing weeks of manual editing and production budgets over $5,000.
What is Seedance 2.0?
Seedance 2.0 is a multi-modal AI video generator developed by ByteDance (the company behind TikTok). It accepts text prompts, images (JPEG, PNG, WebP, max 10MB each, up to 2), video clips (MP4, MOV), and audio files (MP3, WAV) as input and outputs video with synchronized audio — dialogue, Foley effects, and background music generated natively. The platform runs in a web browser and supports 8 languages for lip-synced voiceover.
Key Features
- Multi-Modal Input with @asset tag system — Combine text, images, video clips, and audio in one generation. Tag @Image1 as a character, @Video1 as camera reference, and describe the rest in plain text.
- Audio-Native Generation — Lip-synced dialogue, sound effects, and background music render alongside the video in 8 languages. No post-production audio syncing needed.
- Multi-Shot Narrative — Generate connected 4–15 second clips that maintain consistent character appearance, clothing, and lighting across cuts. Compose up to 2-minute stories automatically.
- Director-Level Control — Edit any scene with a single sentence: swap a character, remove an object, change camera angle. No need to re-prompt the entire generation.
- Resolution and Aspect Options — Output at 480p, 720p, or 1080p (Pro+ for 2K). Aspect ratios include 16:9, 9:16, 1:1, 4:3, 3:2, 21:9. Duration choices: 4s, 8s, 12s.
