PowerPoint Presentations with Embedded Videos Choppy and Freezing


  • When we run presentations with embedded audio and video using PowerPoint 2007 on Windows XP Pro 64 bit SP2 and Windows 7 Pro 64 bit, the presentation will often freeze on a slide that contains video and audio.  The computers that these presentations are being run on are high-end.  The same presentations seem to run all the way through on much slower computers that run a 32 bit operating system.  Is there some kind of incompatibility with Powerpoint 2007 and 64 bit operating systems?

  • Hi,


    Try to reduce the hardware acceleration setting of the display device:

    1. Click Start, click Run, type desk.cpl, and then click OK. Click the Settings tab, and then click Advanced.

    Or, go to: Control Panel\Appearance and Personalization\Display\Screen Resolution, click Advanced settings button.

    1. Click the Troubleshoot tab, and then move the Hardware acceleration slider to None.
    2. Click Apply, and then click OK two times.

    Best Regards,


    Sally Tang

  • I read about the hardware acceleration setting reduction for this Powerpoint issue in some Microsoft documentation, but we cannot reduce the performance of the graphics card because we have other applications running on that computer that are very graphics intensive.

  • Hardware acceleration cannot be disabled for the entire system in Windows Vista or 7 because the OSs rely on it. So the key is to disable it for the spectific application.

    Find the application executible (POWERPNT.exe). For Powerpoint 2007 on a 32-bit system it's in C:\Program Files\Microsoft Office\Office12. Right click on it and click properties, then Compatibility. Select "Disable Visual Theames" and "Disable desktop composition".

    This forces the Windows 7 Basic Theam while the program is running and turns off transparency.  This solved it for me.
