Hi JTHoward,
We apologize for the inconvenience that this may have caused you.
This issue can be caused by corrupted codecs, or outdated video driver. To troubleshoot this, please follow these steps:
1. Ensure that you have the latest version for Windows Movie Maker. You can download the latest
version here.
2. Ensure that you have the proper codecs to play your videos and audio files. Audio
and Video require codecs to play the file and it’s important to have the right codecs installed or updated in your PC.
· Try running the
Microsoft Fix It tool for codecs.
·
Media info will be able to identify the codec required for your audio and video files, and will provide a link to the website for the required codec.
You can get it here.
Note: If you can't find the codec you need you may convert the video to a supported
format (eg. wmv) and then add it to your Movie Maker project.
3. Ensure that your video card drivers are up to date. Movie Maker makes extensive use of the
video card GPU (graphics processing unit). The display driver affects the reliability, performance, and compatibility of the video card with various software.
To determine the version and video card driver date, run the DirectX Diagnostic Tool (dxdiag):
a. Type dxdiag in the Start screen, then
press Enter key on the keyboard.
b. Click on the Display tab and you will see the driver details including the driver version.
c. If your video card driver seems outdated please go to the video card driver manufacturer and see if a newer version is available.
Thanks.
