Ha! Good thinking! Color space of the "faulty" project was set to YCbCR 709 / S-log3. When I set ordinary YCbCR 709 MOV returned to dropdown menu in export. Thanks everybody! The thread is ready to be closed.

Indeed. This project does not show MOV export. My other project does. Weird.

Unfortunately "Open EXR" in my Avid ends the list.

"Open EXR" ends the list in my Avid. In .4 it was fine.

Hello. Since 2020.4 Ive use the MOV with UME export. Today i updated to .6 and saddly my preset for UME is blank and there is no MOV to choose from the dropdown menu. Is it moved somewhere else or is it a bug? Im adding the screenshot for my dropdown.

I jumped on that granade and reinstalled appman and MC. It helped.

Same problem here. Any fix for that issue?
