Up to date premiere pro, and imac 2020. Shooting a73 in HLG and recording straight to atomos ninja v.
The issue is, everything looks wonderful in my timeline (using hlg lut from Leeming), but on export, all goes totally wrong. It looks wildly different even in the export preview, before exporting, and depending on what codec I export to (usually h.264, I use my own made presets that have worked fine for drones and camera recordings - ninja v seems to be the issue) results vary from oversaturated to over exposed - all totally unusable.
I did try exporting original file, that does maintain the color and exposure but runs me something like 7 gigs for the one minute clip - then tried putting this file into media encoder and the same problem persists. Feeling like I missed a box to click on somewhere!
