Keynote Randomly Fails to Play Video

Hello all

Mac user here, armed with a 2017 Macbook Pro.

I use it extensively for business presentations, and specifically, Keynote presentations featuring video.

A handful of these videos will without explanation either load or not load, seemingly at random.

Even after testing a specific HDMI setup before a presentation, said video still on occasion fails to launch.

Any idea on what might be causing this? It is doing the reputation of my technical proficiency no end of harm.

Thanks,

James

Test the video in QuickTime Player, does it play correctly?

If it plays without problems, reset Keynote as follows, completing all of the steps in the order listed:

1. ensure you have a current backup of all your user files saved to a separate drive

2. close all applications

3. uninstall Keynote; for this procedure to work, an application removal tool must be used, App Delete has a free trial and works for this procedure. It can be downloaded from the developer’s website here: App Delete

4. empty the Trash (Finder > Empty Trash)

5. restart the Mac (Apple Menu > Restart) Immediately after the Apple bong sound, press the shift key on the keyboard, release shift when the Apple icon appears. Start up will take longer than usual as the Mac is performing a software repair of the start up drive.

6. After the Mac is fully powered up, restart the Mac normally: Apple Menu > Restart

7. reinstall Keynote from the Mac App Store in the Applications folder

8. Restart the Mac again
