As usual I am a little lost but if you are referring to using DT to edit tiffs spit out from log video and correcting that in DT with a LUT like you would a video editor I think you will likely need to move the LUT module and not use it where it is…even then I am not sure exactly where or of the results. You would have to expt. Then maybe depending on what you typically end up with you might find that filmic might not even be what you would want to use…its just a global tone mapper
In any case you might find some of the discussion from here touches on this aspect of DT…
