How Seedance V2 shocked the industry: 1,000+ data specialists and licensed cinema-grade footage, not scraped Douyin

New details on why ByteDance's Seedance V2 stunned the industry: a 1,000+ person data evaluation operation pairs every algorithm engineer with 10+ dedicated data specialists and an internal 'data product manager'. Crucially, Seedance almost entirely avoided scraping Douyin/TikTok clips, instead buying massive volumes of cinema-grade film/TV footage (especially complex running/jumping/combat scenes), 3D game recordings, and professional interior scans, then using LLMs to decompose them into frame-accurate scripts and storyboards.
