Hi,
I'm interested in outputting video to a local mixer but require a non-standard video transfer function (i.e. not ITU-R BT.601, ITU-R BT.709 or ITU-R BT.2020).
Is there a way to output a clean feed of the sensor with a LUT altering the output in ML?
Happy to try and write a module if not. Does anyone know the colour space of the sensor output that I would need to transform from?

No chance.
The closest you will get is using a 5D mark III for clean HDMI 4:2:0 and a picture style (basically an ICC profile) but picture styles are non-linear and not invertible. Cinestyle is 8bit log and can be inverted well with cineon tools but there is still a non-linear lut in there (Canon Standard).
You can work out the chromaticity and white point xy values of a specific camera from the color matrices found in a DNG (converted with Adobe DNG converter). You'll need to multiply the inverted and transposed XYZ D50 to Camera native RGB color matrices (2 solved for each sensor under A and D65 illuminants) by the Canon white balance coefficients (in a 3x3 matrix) plus chromatically adapt the white point from D50 to D65 before you even get started trying to linearize the actual picture style - all in 8bit i.e. there is little point even trying.

I met a similar problem last week and they solved it.
