Seedance 2.5 is Rivya's larger Seedance workflow for prompt-only video, first- and last-frame guidance, multimodal references, and video-guided transformation. It adds a 1080p tier, output up to 30 seconds, automatic duration, MP4 or MOV output, and substantially larger image, video, and audio reference capacity than Mini.
Why consider it
Consider it when your next task needs Up to 50 reference files.
ByteDance's full Seedance 2.0 video model with explicit support for prompt-only generation, frame-driven animation, and multimodal reference generation. Rivya keeps the documented role split explicit so frame inputs and multimodal references stay mutually exclusive instead of collapsing into one ambiguous upload bucket.
Why consider it
Consider it when your next task needs Prompt, frames, or image/video/audio references.
ByteDance's faster Seedance 2.0 video model with full scene routing for prompt-only generation, frame-driven image animation, and multimodal reference video generation. Rivya keeps the documented scene split explicit so first/last-frame inputs do not collide with reference image, video, and audio roles.
