MP4 videos and Presenter '13

Hi Nikki!

You can see from our tutorial here, that yes MP4 videos are supported.

Are you having an issue in all Presenter projects or just this one?

If it's just this project, perhaps it has become corrupted:

You may be able to resolve PowerPoint file corruption in this manner:

1. Open a new, blank presentation in PowerPoint.
2. Go to the Home tab, click the drop-down arrow beside New Slide, and choose Reuse Slides.
3. In the Reuse Slides panel, click the Browse button and choose Browse File.
4. Browse to your original PowerPoint file and click Open.
5. At the bottom of the Reuse Slides panel, mark the box to Keep source formatting.
6. Right-click the first slide in the Reuse Slides panel and select Insert All Slides.
7. Save the new presentation and republish.

Note: Articulate resources, such as audio and video, will need to be inserted again into the new presentation. You may need to export the narration from your original presentation, then import it into the new presentation.

Many thanks!!!  It turnsout that the PowerPoint slides were the source of the problem.

Glad you were able to get that sorted Nikki and thanks for popping in with an update
