Seedance 2.0: ByteDance Cracks 90-Second AI Video With Native Audio Sync — API Now Live on fal.ai

ByteDance Seed·medium signal

ByteDance's Seedance 2.0 launched internationally in April with 90-second video generation featuring native audio sync and cross-scene continuity, a significant leap from the 5-10 second clips that defined early AI video. The model is now accessible via fal.ai API and integrated into CapCut, putting production-quality AI video generation directly into ByteDance's existing creator ecosystem. For builders, the fal.ai API availability means 90-second AI video is now programmable infrastructure, not just a demo.
