There are now one or two excellent online tutorials for grading in HDR for delivery to YouTube, however (1) they restrict the discussion to V-Log L; (2) the workflows are either in DaVinci Resolve or NLEs other than FCPX; (3) they require the use of expensive external monitors and (4) they’re overly long and complicated, which may deter some from dipping their toes into the rewarding world of HDR. No question, if you intend to do much grading, it is preferable to shoot V-Log L for HDR10 delivery. But if you want to turn your YouTube projects around as quickly as possible, HLG is a great alternative – the order of operations couldn’t be more simple and the results may surprise you!
