I'm trying to export a really big video, almost 7 hours, and I left my PC exporting it and I was skimming through it when it was done and then there was this brief glitch that looked like something from cable TV, that also messed up the audio, and judging by how soon into the video it happened I'm sure it's likely there throughout the whole video. Why is that happening and how do I export it (in a high quality of course) without it doing that?
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.
If that doesn’t work, try updating or rolling back your graphics driver directly from the video card manufacturer’s site. If NVIDIA, do a clean install of the latest Studio Driver (NOT the Game Driver)
If that doesn't work, try creating a new project and import the old one into it.
