Can I confirm order of operations when using a LUT for LOG?

My understanding, per some excellent advice in these forums, is that I should adjust the basics first and then apply the LUT (for N-Log) so that PP will first apply the Basic Corrections and then the LUT  under the Creative tab. 

 

Personally, I gravitate towards using the adjustment layers for correcting/coloring the video. So what I've been doing until now is Video 1, footage 

Video 2, LUT

Video 3, Lumetrie effects. 

Correcting my footage this way, are the Lumetrie effects happening first, then the LUT? I want to confirm. 

 

Lastly, I recently learned if you right click in the Assembly Window, choose Modify, Interpet Footage, at the very bottom is an option to apply a LUT. If we choose to add the LUT there, when is the LUT applied in the order of operations? Is the LUT applied first, before Lumetri corrections or after? (I'm assuming first, but I want to confirm.)

 

Thank you,

Hokay ... there's a change I'm still trying to puzzle out in the 2022,  and that is that we seem to be able to use an input LUT in the Modify/Interpret CM section that seems applied after the Lumetri on V1 is is processed. So the work seems to be 'through' the LUT, more like it's an output transform.

 

Trying to verify that, but that is what it seems to have done.

 

Other than that ... order of processing has been straight forward.

 

Within a Lumetri instance, top down. So yes, applying a LUT in the Creative tab  means Basic tab corrections are applied before the LUT, but anything else in the Creative tab and down is processed after the LUT.

 

Lumetri instances, like all other effects, are processed top-down in the order they appear in the Effects Contol panel (ECP).

 

With Adjustment layers above ... V1 is processed, then the AL with effects on V2 with all effects there within that track processed top down.

 

AL on V3 is processed after the AL on V2. And on up the line.
