In the timeline, we naturally made many changes over and over again.


And if everytime we made changes in the timeline, FCPX renders it to ProRes 422, then our ext HDD will be very fast fill up of unwanted rendered files. How do we delete these files ?


My Rendering background has been turn on from day one !

    In the project view select the project and use File>Delete Project Render Files...

    Someone else may wish to confirm this but I think that is the case if you select delete "all" render files. However, if you have Background Rendering "on" in preferences then FCP will, I think, rebuild the files when you re-enter the project.

    From page 401 of the FCP X 10.0.6 Manual:-


    Delete render files to free up disk space


    Project and clip render files are stored in your Final Cut Events and Final Cut Projects folders. Over time, these files can accumulate and take up disk space. If you want to free up hard disk space, you can either delete unused render files or delete all of the render files for a particular compound clip or Final Cut Pro project.


    Delete project render files


    1 Select a project in the Project Library.

    2 Choose File > Delete Project Render Files.

    3 In the window that appears, choose to delete Unused Render Files Only or All Render Files, and click OK.


    Delete event render files


    1 Select an event in the Event Browser.

    2 Choose File > Delete Event Render Files.

    3 In the window that appears, choose to delete Unused Render Files Only or All Render Files, and click OK.

    If you delete all render files with background rendering on, it will start re-building (re=rendering) them automatically.


    If you don't have background rendering on, control shift R will accomplish the same thing.


    As long as you're getting real time  playback you might consider not rendering at all.


    Good luck,
