I'd like to add a video as a background to each slide for a work presentation. However, Keynote 6.2 will play some of the inserted videos, but not others. I've tried both .mov and .mp4 formats and neither work. Any idea what's going on? Thank you.

MacBook Pro, OS X Mavericks (10.9.3)

    You drag and drop the file on to the slide, click to select, then go to:  Inspector > Format > remove the tick in:  start movie on click?

    It isn't ticked for any of the inserted videos.

    What CODEC is used in the QuickTime files?

    Open the file n Quicktime:     Window > Show Movie Inspector, the CODEC is shown against:  Format

    You can also repair Keynote using this, ensure you complete all the tasks and in the order shown:


    delete all the iWork applications if you have them, not just Keynote, using Appcleaner from Mac Update, its a freeware application


    empty the trash:  Finder > Empty Trash


    Shut down your Mac, wait 30 seconds, then power on the Mac, immediately after the start chime, hold down the Shift key

    When you see the grey Apple symbol and progress indicator (a spinning gear), release the Shift key.

    If you are prompted to log in, type your password, then hold down the Shift key again as you click Log in. 

    Let the Mac fully boot up, it will take longer as the OS is repairing the drive



    when fully booted, go to Applications > Utilities > Disc Utility; click on the boot drive then First Aid tab and click repair disc permissions



    when complete, restart the Mac normally, Apple menu > Restart


    install Keynote from the Mac App Store

    I am having the same issue and it is frustrating. If you find a solution, please share.

    Found my problem. It was a problem with my ordering in the animations. The video appeared last, and therefore wouldn't play. Hopes this helps.
