Here are some general troubleshooting tips for Adobe Premiere Pro.
Holding down Shift+ALT while Premiere Pro launches until the Welcome screen appears. This will reset both the preferences and plugin loading cache.
Close Premiere Pro and using Windows Explorer, navigate to the proper location(*) on the hard drive and manually delete all Cache folders along with the Peak Files.
Next time when you reopen the project, the cache file will rebuild itself.
* There is a Premiere Pro preference that shows the location of the Cache File Database. Go to the Premiere Pro Preferences > Media Cache. Here you can find the Media Cache File location on your computer.
Extremely large stills may sometimes cause issues. Try to lower the resolution for stills to save memory pressure.
Premiere Pro has different render engines for performance. You can easily switch between them. In case of trouble, try switching from GPU to Software or visa Versa.
In the Premiere Pro menu, go to:
File > Project Settings > General. Under “Video Rendering and Playback,” there’s a “Renderer” dropdown. From this dropdown, you can select a different renderer. E.g. select “Mercury Playback Engine GPU Acceleration (Metal)”
- Update your graphics card drivers.
New graphics drivers can be found on your graphics card manufacturers website (e.g. Nvidia or AMD)
This does not apply to macOS users unless you are using CUDA web-drivers. New graphics drivers for macOS come with OS updates. Because of this reason, we recommend you don't stay more than 1 or 2 major versions of macOS behind.
Just restarting your computer will sometimes solve things. Why? Well each time you open up an application, this may leave something in your computer's memory, building-up memory pressure. It's good to reboot your device every once in a while.
