Consider the following scenario. In Microsoft PowerPoint 2010, you insert a video on a slide. The video uses one of the following video formats:
- QuickTime (*.mov)
- MPEG-4 (*.mp4)
Then, you set the video to play automatically. On the Animations
tab, you set the video to play across a set number of slides. In this scenario, when you show the presentation, the video does not start. Additionally, you receive the following error message:
The file you are attempting to play has an extension (.mov) that does not match the file format. Playing the file may result in unexpected behavior. Do you want the Player to try to play this content?
If you click Yes
, the video does not play. Instead, a blank frame is displayed on the slide.
