Stock Keyer run in AlexaV3LogC; alpha is copied back onto the original plate.
Keyer Log converts the input to AlexaV3LogC, runs Nuke's Keyer (default luminance key), converts color back, and Copy-merges the resulting alpha onto the ungraded plate.
Keyer knobs (input, output, combine, invert, operation, range) are linked to the group. Use when a linear key fights HDR/log plates.
