The official Movie Recorder page lists six ProRes codecs, says the ProRes encoder supports Stereo only, does not support variable frame rate, and is unsupported on Linux and Windows Arm64. It contains no colour, tonemapping, Rec. 709, Rec. 2020, PQ or HLG statement (0 hits in the whole 15,316-character page; 0 also in the linear-sRGB page for 709/2020/HLG/PQ and 0 in the changelog apart from dates). CA-B309's "Movie docs contain no colour-tag or tonemapping setting" is corroborated as an absence; "ProRes encoder hard-codes Rec. 709 with Rec. 2020/PQ/HLG commented out" is code-only (ProResEncoder.cs in the mirror) and cannot be byte-checked without the archive.
