Some videos won't play in any format on Keynote.

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)

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:


1

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


2

empty the trash: Finder > Empty Trash


3

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


4

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


5

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


6

install Keynote from the Mac App Store
