Seedance 2 5 Reference To Video

# Seedance 2.5 Reference to Video

## When to pick this model (vs siblings)

Seedance 2.5 Reference to Video's distinct property is **reference-conditioned generation at delivery resolution**: identity, product geometry, and art direction come from your reference stack rather than from prose, and the output lands at 1080p so you are not upscaling a draft. RunComfy positions it for *consistent character finals, product reference films, and style-locked brand clips*.
