I've asked before about the use of LUT is the real world and if they are taken as gospel or just as a suggestion. The response before was they were used as a reference point and then usually taken off in post once in online/color correction. Today I have a myriad of media some F-55 4K and other XAVC- Intra 100 and I believe some go pro footage just for fun. I was given a bunch of luts for each camera and the section of the show like open, Exterior Act etc... As I've previously posted today Avid 8.3.1 automatically added the "YCbCr Sony SGamut3.Cine (SLog3 gamma)" Color Transformation. To be thorough I went ahead and imported all the LUTs I was given from production and for the most part they are useless. They all go well below 0 millivolts and over 700. They aren't too far from the Avid default LUT but in every case I look at the standard LUT Avid applied is more accurate and completely legal. I can see sometimes they added a bit of blue and lessened the Red but nothing major. I'm basically ignoring the field LUTs as they aren't helpful at all. I figure they were developed so things look okay on the set monitors but clearly they weren't looking at any kind of waveform.
Is this typical for those that get LUTS from the field? I haven't been in the field in a long time so I don't know much about the workflow of Video Village especially for these multicamera no production truck setups. Or I should say minimal production truck without a full tilt switcher etc... Are the LUTs generated in the Camera on the video tap to feed the control room monitors. I assume the Cameras are recording their raw data and the LUT is introduced just in the on set monitors but where does it come from? The DIT gives me these files for different cameras and different show scenes. Did he create them in a monitor interface box or pull them from the cameras? Curious how this works in the field. TIA
