Can't change clip duration Motion 5
I have tried all of the work arounds I have been able to find in the Support Commnity and still I can't change the duration of source clips in Motion 5. I have trashed plist, rebooted, repaired permisions, changed timing of project, changed name of clip, used the Timeline clock instead of the Instpector window. Cleared all In / Out points and reset them to slightly different values. I have changed Timing to Variable and back again. I can open clips in a new project and change duration. I have opened new project and copied some layers from working project, the problem persists. Is reinstall the option left available to me?
