Relatively new user here... I recently went back to a project from the holidays and wanted to tweak a few things. I wanted to start by rendering down all the old clips, which I had previously not done out of ignorance (now I know better). This took a while, but after completion all but a .png and a single clip remain in the monitor on playback. The other clips still exist in the timeline, and if I double click them in the timeline they will all individually appear in the monitor. But the original "virtual choir" layout is gone.
If I right click and try to revert back to an unrendered clip, there is no improvement. If I delete the clip and manually add it back in, it doesn't appear in the monitor. I'm also unable to undo the render, so my original project seems lost. I'm sure I'm missing something relatively fundamental here...
Screenshot for reference. Let me know if I can provide other info.
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.
