Video : Presentation

Video for PowerPoint: There are 4 elements to consider when crafting video for insertion into PowerPoint

1) File format: We recommend .wmv (Windows Media), .mpg (Mpeg 2) or .avi. While it is possible to use QuickTime by using a hyperlink, we advise against it. For audio only files .mid, .mp3, .wav, and .wma file formats may be used.

2) Movie Size: The size of your movie when you create or convert it will impact the size of the image in your PowerPoint show. While you can enlarge or shrink your movie in PowerPoint, the best results will be obtained when you display the movie in the size you create. You will have a number of options and I recommend experimenting to see which best suits your needs (i.e. a small video window vs. a full frame video). For a standard 4x3 PowerPoint page options range from 176x144 to 640x480 for full screen. For wide screen PowerPoint shows you can try resolutions from 480x272 up to 1280x720. Again, experiment to see what works best for you.

3) It is vital to understand that movies inserted into a slide show are NOT included in that show’s file. That is, the movie is not copied but rather is represented by a link. So, if you save your file and move it to another computer the movie cannot be shown. Under the “Office Button” you will find the command for “Publish” and “Package for CD.” This wizard will prepare and move all of the files (slide show, audio files, video files, etc.) and move them to a CD in such a way as all of the parts are where they need to be.

4) Test, test, test. Even if you do everything right, a show built on one computer may not work on another. Conflicts between graphics cards and projection systems are likely to be the problem. If your video does not play on the presentation system, try using your function key to turn off the computer display so only the projector is seen. An in depth discussion of the perils of connecting laptops to presentation systems can be found here (link to LLN article when published). Alternatively, you may try to run your video outside of PowerPoint as a last resort. For a presentations in PowerPoint (PC/Mac) or Keynote (Mac) we recommend the following file types.

Standard formats for Mac: .m4v, .mov.

Standard format for Mac: .mpeg
Mpeg 1 is the most compatible with all versions of PowerPoint.
