About Topaz Hyperion HDR
Topaz Hyperion is an HDR video model that converts SDR footage into HDR with selectable transfer functions (PQ or HLG) and tunable exposure, saturation, and highlight handling.
Pair with ProRes output for professional editing workflows; H265 output is also supported.
This is the legacy Hyperion (HYP-1) model. For new work, prefer Topaz Hyperion 2, which is actively developed.
