(Jack Wallen @ SMB Technologist) Power users of presentation applications go beyond the standard-issue text and fancy backgrounds for their slides. Their presentations frequently include sounds, images, and sometimes video. Fortunately, with the open source flagship office suite LibreOffice, embedding videos into a presentation is as simple as adding text to a slide. I'll demonstrate how simple it is to embed video into a LibreOffice Impress slide. 

A caveat: The only format that is readily supported is the Ogg Vorbis video. Fear not -- there are plenty of ways to convert nearly any format into an Ogg Vorbis video. I will first show one method of converting your video, and then we'll embed that video into a presentation.

Converting your video format

My conversion method of choice is done with the help of OpenShot Video Editor. With this editor, you can import nearly any format and export it to almost any format. Here's how to get your video into a suitable format for embedding into a presentation:

1. Open OpenShot.
2. Go to File | Import Files and add your file.
3. Go to File | Export Video and in the Export window select All Formats from the Profile drop-down (Figure A).
4. Give the file a name.
5. Select the Export To Folder location.
6. Select Ogg (theora/vorbis) from the Target drop-down.
7. Select DV/DVD NTSC from the Video Profile drop-down.
8. Select either Med or High for Quality.
9. Click the Export Video button.

Embedding the video into a presentation

The size of your video will seriously affect the size of your overall presentation; it will also dictate the how much time is required to handle the actual embedding. If the file is large (I've embedded files that are larger than 600 MB), Impress might become temporarily unresponsive and look as if it will crash at any moment. Wait for the embedding to complete before force closing the application.

Here's how to embed your video:

1. Open a presentation.
2. Go to Insert | Movie and Sound.
3. Locate the video to be inserted and click Open.

Once embedded (which may take a while), you can test to make sure the video plays by clicking F5, which will start the slide show (Figure B).

To give the video-embedded slide more of a seamless look, you might get rid of any text on the page and change the page background to black. To change the background color and give the video-embedded site a cleaner appearance, follow these steps:

1. Go to Format | Page.
2. Select Color from the Fill drop-down.
3. Select Black.
4. Click OK.
5. When asked, do this for only this page (not all pages).

Summary

The embedding of video into your Impress slide shows is an easy way to dazzle your audience. You could even use this technique to create self-guided presentations, which could be especially useful if you have a paralyzing fear of public speaking.
