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

ByteDance has released Seedance 2.5, an AI model capable of generating video clips up to 30 seconds long with synchronized audio. By allowing users to upload multiple reference files, the tool offers greater control over visual and auditory output than previous offerings. This extended duration and integrated audio capability could streamline production workflows for advertising teams by reducing the need for separate software to generate and align sound with video content.
