  • If exporting to YUV 422 or 420 video (e.g. h.264/h.265) or gray-scale, use the Luminance/Chroma option – not supported by ffmpeg (yet).

* In the specific case of a final export, PXR24 is considered lossless, as there should not be any need for 32-bit float data.

  • If exporting to YUV 422 or 420 video (e.g. h.264/h.265) or gray-scale , use the Luminance/Chroma option. – not supported by ffmpeg (yet).
