I often use masks in PP, it always worked, but now, whenever i use masks (opacity or on other effects) PP will Freez, preview of video is all glitche, and so on. Once i overcome it with reseting premier every minute, while masking, but then after rendering, the video was totally useless (all glitchy) audio worked jsut fine.
I reset preference, optimazed settings and perfermonce. Updated Premier to newest version, tried it in new projects with whole new preferences. And Masking alway don't work. Everything else work perfectly fine.
I don't know what to do with it.
Crash, Effects and Titles, Error or problem, Freeze or hang
If that doesn't work, try resetting the Workspaces: Reset a workspace Reset the current workspace to return to its original, saved layout of panels. 1. Do one of the following: • Click the Workspace menu icon and select Reset to Saved Layout. • Choose Window > Workspace > Reset to Saved Layout. from here: https://helpx.adobe.com/premiere-pro/using/workspaces.html
If that doesn't work, try Preferences > Audio Hardware and set Input to None.
