New update blew away my LUT presets. Went back to old project to make some tweaks - replaced all my LUTS with some random ARRIS LUT. New update makes you convert old projects but loses track of installed LUTS?
It depends on whether you had those LUTs in the correct place or not.
As ... IF you put your LUTs in the Premiere program file LUTs folders, (BAD choice ... ) this will happen, as they stay with that Premiere version.
But ... IF you put them say in the Program/Package files/Adobe/Common/LUTs/ ... then folders for Input, Technical, and Creative, they should work across all installed instances of Premiere, MediaEncoder, and AfterEffects.
