Manually Generating Thumbnail Cache Files

You can manually generate thumbnail cache files. This is necessary if a thumbnail cache file could not be generated during import because the folder is write-protected, or because you have edited the file with an external video editing application.


  • Do one of the following:
    • In the Pool, right-click the video file and select Generate Thumbnail Cache.

    • In the Project window, select the video event and select Media > Generate Thumbnail Cache.


    You can only refresh already existing thumbnail cache files from within the Pool.


The thumbnail cache file is generated in the background so that you can continue working with Cubase.
