ByteDance's Seedance 2.5 generates 30-second video clips with built-in audio

ByteDance just shipped Seedance 2.5, an AI video model that produces video and audio together in one go. Each clip runs up to 30 seconds, three times what Google's Gemini Omni Flash puts out. Users can feed in dozens of images, videos, and audio files as reference. For ad teams, this could kill the process of cutting together one short clip at a time.
