Runway Ruby generates or converts video into 16-bit EXR sequences or 10-bit and 12-bit ProRes and HEVC files from any video model inside Runway. Runway's walkthrough breaks down what separates real HDR from SDR in a costume: bit depth, BT.2020 color and the transfer function, and when to reach for PQ versus HLG. Ruby also added support for alpha channels on 9/18/26.

After Ray3 and LTX-2.5 put EXR output inside single models, Ruby makes it a finishing layer over every model in the roster. A generated shot can now sit in a grade next to camera footage without giving itself away, which is the last gap most delivery pipelines cared about.
