If you have to deal with presentations a lot, you might have already come across a situation where you needed to embed one PowerPoint in another. Sure enough, there are ways of how you can do this using PowerPoint or with iSpring Pro PowerPoint add-in:

Using PowerPoint

1. In an opened PowerPoint presentation, select a slide where you want to embed another presentation (it’s easier to find the right position in the View -> Slider Sorter mode and double-click a desired slide).
2. Go to the Insert tab and click Object.
3. Now browse for the presentation file you would like to embed. Once you select a file, click Ok twice to close both windows. You will see that the presentation you’ve selected appear as a thumbnail on your slide.
4. Your embedded presentation can play either by clicking on a presentation thumbnail in a slideshow view or automatically.
   To have it start playing automatically in PowerPoint 2007, go to the Animations tab, then select Custom Animation. Chose the embedded presentation thumbnail and click Add Effect > Object Actions > Show.
5. To have the embedded presentation start playing automatically in PowerPoint 2010, select the thumbnail, go to the Animation tab, click Custom Animation and select OLE Action Verbs. In the opened window select Show.
6. Make sure to change the Start from "On Click" to "After Previous".

Drawbacks:

1. The embedded presentation opens up in a full screen mode and covers up the slide it’s on and the entire screen.
2. You have to click on the presentation thumbnail in order to start playing it within the other one.

Using iSpring Pro

1. Convert the presentation you want to embed into another presentation to the Flash format with iSpring PPT to Flash converter: (iSpring tab> Publish>Publish). Feel free to download iSpring Pro 30-day trial.
2. Insert the newly-generated Flash file into the second PowerPoint using the Insert Flash feature on the iSpring toolbar. Please note, the inserted Flash movie plays back in the SlideShow mode in PowerPoint.
3. Optionally you can convert your PowerPoint with the inserted presentation to Flash for easy delivery online or by email.

Advantages:

1. The embedded presentation will blend into the project and will start automatically, whenever you want it to.
2. Most importantly, the embedded Flash file will only occupy the area you give it on a slide, instead of covering up the entire space. (Although it is possible, if that’s what you want.)

As you can see, the iSpring method is much simpler and has no drawbacks. So check out iSpring Pro PowerPoint to Flash converter, if you want to do it the easier way.
