Frequently Asked Question

The following items won't be included in a video that you create using PowerPoint:

• Media inserted in previous versions of PowerPoint. To include these, you can convert or upgrade the media object.

• For example, if you inserted the media using PowerPoint 2007, it will be linked and it will play in the presentation. However, when you export the file as a video, the linked media will be dropped. You can convert the file to the new file format (select the File tab, and under Info, select Convert), or you can right-click the media object and then select it to upgrade; it will embed the file and export it correctly.

• QuickTime media (unless you have a third-party QuickTime codec named ffdShow installed and you have optimized for compatibility)

• Macros

• OLE/ActiveX controls
