Seedance 2.5 is a web-based video creation platform for generating and editing short videos without filming. Users can describe a scene or upload an image, then create text-to-video or image-to-video sequences up to 30 seconds. The platform accepts up to 50 multimodal references, including images, videos, and audio, to maintain consistency across faces, clothing, props, and scenes. Frame-based editing supports background replacement, object removal, product replacement, and style transfer without regenerating the entire video. Additional controls include aspect ratios, 480p or 720p output, camera and lighting direction, negative prompts, video extension, and synchronized audio generation. Completed projects can be exported as high-bitrate MP4 or MOV files. Paid plans add credits, faster processing, storage, and commercial-use permissions.
