TikTok added ByteDance’s Seedance 2.0 AI video generation model to its Symphony ad toolkit, giving advertisers the ability to generate realistic video content from text prompts, images, or reference clips with audio automatically synced. The model improves product consistency across video segments and produces smoother motion than previous versions, reducing the need for manual corrections before campaigns can scale. Seedance 2.0 was made available in CapCut in select markets last month before rolling out to Symphony’s ad creation suite.
