Seedance 2.0 AI Video Generator
Create Videos with Sound, Search & Cinematic Quality Using Seedance 2.0
Seedance 2.0 is ByteDance's next-generation AI video model. Generate up to 15-second videos with synchronized audio, real-time web search integration, and support for both text-to-video and image-to-video workflows. From cinematic storytelling to social content, Seedance 2.0 delivers professional results with natural motion and immersive sound.
Seedance 2.0, released by ByteDance in March 2026, is the successor to the Seedance 1.0 Pro model and represents ByteDance's most capable video generation system. The model introduces two features not found in most competitors: real-time web search integration that pulls current information (weather, news, product data) into generated video content, and a unified audio generation pipeline that produces synchronized voice, sound effects, and background music at no additional cost.
The model supports 480p and 720p output across seven aspect ratios (16:9, 9:16, 1:1, 4:3, 3:4, 21:9, and adaptive mode) with video durations ranging from 4 to 15 seconds. For image-to-video workflows, users can upload one image for first-frame generation or two images for first-and-last-frame control, enabling precise scene transitions. The web search feature is available exclusively in text-to-video mode and can be toggled on or off per generation.
Seedance 2.0 was developed using ByteDance's internal video understanding and generation research, leveraging TikTok's massive video dataset for training signal. Compared to Seedance 1.0 Pro, which focused primarily on cinematic motion and multi-shot storytelling, Seedance 2.0 adds audio synthesis, web grounding, and improved temporal coherence. Against competitors like Sora 2 (which offers higher 1080p resolution) and Happy Horse 1.0 (which leads in motion quality rankings), Seedance 2.0 carves out a niche with its web search capability and competitive pricing on LoveGen AI.
