Using Slides to Make Videos

When you want to broadcast a message, don’t underestimate the versatility of slide shows, especially for community bulletin boards and announcements. The most recent versions of PowerPoint and Keynote offer two very quick and user-friendly ways to convert a slide deck, with narration or sound, into a video. Export these as .mov or .wmv files, drag them into TelVue Connect for transcoding to proper broadcast specs, and you can easily schedule attractive, custom-made bulletin boards in your channel lineup.

Why convert a slide presentation to video?

  • You can customize the look and feel of your billboards by harnessing the sophisticated graphic tools in PowerPoint and Keynote.
  • Give the creator a great deal of artistic freedom
  • It is easy to learn, and an easy way to teach others to create bulletin boards
  • You have many options to enhance a slide show with audio and special effects.

Some pointers:
In PowerPoint 2010 or later, you simply “Save as Movie”, and your slides will play at the default speed of 5 secs/slide. If you want to get fancier, click on “Movie Options”, and you can change aspect ratio, add soundtrack, even add credits.

If you want to customize the timing of your slide show, or record a live narration timed to your slide show, go to the “Slide Show” menu, select “Record a Slide Show”, and just start talking while advancing the slides. (Tip: record this in a quiet place, and it will go much more smoothly with a script…)

Unfortunately, there is a glitch. PowerPoint 2011 for Mac does NOT export the audio! So Mac Users can either:

  • Use Keynote, in which case you would create your slideshow, then click on Inspector → Document icon → Audio tab → Record.
  • Or, if you already have a PowerPoint with narration, you can open that file in Keynote
  • Then Share → Export as an .mov (this time WITH audio).

The last step of this process, for broadcasters, is converting the files to broadcast-quality MPEG2, and scheduling these for air. This is most easily accomplished through TelVue Connect, which allows for a simple drag-and-drop upload to your Media Library, where it will be automatically transcoded to your broadcast specs, and from which you can insert the slides, just like any other video, into your program schedule for playout.  I turned this blogpost into a slideshow video.  See for yourself:

    This is great!! What size of sheet should it be set up on? Can I use 17″ wide x 8.5 tall??

    We’re already using PowerPoint for our Messageboard, and I had never considered saving it as a video file, but that’s a great way of doing it! A lot better than tying up a computer to run it into a video router all the time!

    Is there an easy way to overwrite a file though, so you could use the same file even after a new message comes in from the community without having to re-schedule your message board file that’s already set to air?

    I would suggest using the replacement_files feature, as described in an earlier blogpost: Let me know if that works for you.
