MEP Premium V 20.0.1.65 (UDP3), Windows 10 64bit, AMD Ryzen 5 3600
In MEP all the 4k .MOV files out of my 5d4 have no audio. I have the program set to generate and display half wave forms on import which it does for other files. HD .MOV files have no such issue, just the 4k ones. Had up to date Apple Quicktime installed then tried the Quicktime Alternative recommended on the Magix support page. No change. The files play back with audio fine with other players.
