• They should be of high quality.
• They should not be too crowded -- look at movies that contain one or two colors so that any text or other visuals placed over them has sufficient contrast to stand out.
• They should be loopable -- so that even a small movie clip can work.
• The movie clips need to be in a compatible file format -- AVIs work great, although MPEGs and WMVs can be used as well. No QuickTime MOVs though!
  

1. Choose a simple theme (see note in the end of this post) in OfficeFX Professional, and add a Standard default video scene to any slide within the Insert tab (see Figure 1)
   
   
   Figure 1: Match your screen with these options.
   
   
2. Once you have selected the video you want to play in the background, set that video to:
• Repeat Continuously (that's the default).
• Set the Placement to Maximize so that it takes up the full screen.
• Uncheck the "Interactive" option so the insert scene will not respond to user mouse clicks.
• Select the "Place Behind PowerPoint Content" option. That'll display the video behind your PPT content.
3. Now click the the "Assign to All" button.

That's all you need to do!

Now, in PowerPoint you'll see that OfficeFX has placed a stand-in image that represents your video on all the slides. It's no longer an option to have the stand in image or not. If you've got a video insert added, its stand-in image is always displayed in PowerPoint. This maintains the WYSIWYG relationship between PowerPoint and OfficeFX. What you can do is select the stand-in image in PowerPoint and change its display order to push to the back. You'll then see all your PowerPoint content on top of it.

• When presenting a complex chart you can use a virtual pointer to focus the relevant part of that chart. You can drag and drop this focus element step by step, to point at the subarea you are talking about. Doing so, your audience is able to follow you all the time.
• You want to have a surprising intro for your product launch? Draw a curtain to uncover the title of your new product.
• You have to present complex tables? No problem any more! Use a yellow, semi-transparent rectangle to highlight the row you are currently talking about. This visual aid makes it easier for your audience to concentrate on the relevant numbers.
• When presenting the new layout of your clients' business card, you can construct different options, instead of just showing them. Move the logo, name, title and address block to any position desired. This will not only impress your client, it will involve him.
