  • Not Previewing Effects: Always preview your composition (press 0 on your numpad) before finalizing.

Troubleshooting Insights

If you encounter issues, here are some common solutions:

  • Images Not Visible: Ensure layers are not hidden and that the opacity is not set to 0%.
  • Rendering Problems: Check for incompatible file formats or insufficient system resources.
