Seedance 2.0 Fast R2V is the reference-to-video endpoint within ByteDance's Seedance 2.0 video generation family, released in April 2026. Like the standard Seedance 2.0 R2V, it accepts a text prompt alongside reference material and combines them into a single output, with reference elements addressed in the prompt. The "Fast" designation marks it as a latency-optimized sibling alongside the Seedance 2.0 Fast text-to-video and image-to-video variants.

ByteDance describes Seedance 2.0 as built on a unified multimodal architecture that understands combined text, image, video, and audio inputs, referencing visual composition, camera language, motion rhythm, and sound characteristics from the supplied material. According to ByteDance, the model features audio-video joint generation, motion stability, and control over performance, lighting, and camera movement.

Relative to the prior Seedance 1.5 Pro generation, ByteDance reports improved instruction-following and subject consistency, plus new video editing and extension capabilities and up to 15-second multi-shot output with dual-channel audio. The R2V mode emphasizes consistent faces, clothing, and visual style across shots, shifting workflows toward reference-driven creation.
