When you’ve been working on a project a lot, you might find that it’s taking longer and longer to render clips. You’ve got too many rendered clips stores. The fix is easy.
File > Render Manager
Find the folder of the project you are working in and put a check in the delete column next to the audio and video icons (the directions are in the window). Then click OK. This will clear out older rendered clips – this will also clean our your undo cache so make sure you don’t intend on going back to a previous state in your project.
Once it’s finished, you’ll need to render your whole project again.
