Which Unity Recorder 5.1.7 image-sequence settings matter for handing real-time renders to offline finishing (format, bit depth, colour space, alpha)?

For scene-linear handoff, Unity Recorder 5.1.7 documents a narrow combination (HDRP, non-Game-View source, EXR, tonemapping and dithering off) for 'Linear, sRGB (unclamped)'; EXR is written at 16 bits; alpha is unavailable from Game View or non-alpha formats. Curator qualifications: Documentation read 2026-10-22; no engine, exporter or headset run; behaviour not observed. Whether EXR carries chromaticity metadata is undocumented (producer gap). Timing/determinism covered by C2-B15-F2-10 (duplicate family, not repeated). Limitations: Documentation read 2026-10-22; no engine, exporter or headset run; behaviour not observed. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
