    1. Make changes to the file and/or folder
    1. Clear Media Cache Files and Database ✅
    1. Change the File Extension

Adobe Premiere Pro may not function properly with some file formats when the trial version is active. If you have the license for the product, make sure it is activated.

1. Make changes to the file and/or folder

  • Change the file directory: Before attempting to import the file, change the file location and then attempt to import the file.
  • If your file is in one folder, move it to an alternative folder and try to import it from there.
  • Should the issue persist, try to move the file to another disk or partition and try again.

2. Clear Media Cache Files and Database ✅

  • Launch Adobe Premiere Pro.

  1. Click on the Edit menu and select Preferences.

  2. Select the Media tab from the left pane.

  • Here, note down the location for Media Cache Files and Media Cache Database. Copy the location to a notepad or something for better accessibility.

  1. Close the Adobe Premiere Pro app and any other Adobe program running on your computer.

  2. Open the File Explorer and navigate to the Media Cache Files and Media Cache Database locations, one by one.

  3. Rename the folders, Media Cache File, and Media Cache.

  4. Now launch Adobe Premiere Pro again and go to Edit > Preferences > Media.

  5. Click the Clean button for the Media Cache Database folder.

  6. Close and re-launch Adobe Premiere Pro and attempt to import the file with the error and check for any improvements.

3. Change the File Extension

  • Before importing the media file, try to change the default file extension to something else.
  • For instance, if you want to import a .avi file, change the extension to .mpg.
  • This makes Premiere Pro use a more tolerant import format that will accept a non-standardized file as a valid import.
