Bulin 47 AI Video Generator is an independent photo-to-video remix studio. Upload one clear portrait; Seedance 2.5 replaces the lead performer while keeping the street and crowd reference. Output is a silent ~15-second 480p clip — add your own music in TikTok or CapCut. Free to preview photos and guides; generation uses credit packs.
