Welcome to these tutorials, many of which were unique concepts when first published!

PowerPoint 2010 Video Pipeline: how to insert video

Logic: understand the varied ways to insert a video in version 2010

There are now more options to insert video into PowerPoint 2010:

How to insert video into PowerPoint 2010- from file

The first option is to insert a video from file. In previous versions, the default was to link. That kept file sizes small but caused grief when the presentation was moved without the linked video. PowerPoint tried to be clever and would look for that file in the root directory of where the presentation was saved- but the video had to be there. Now, for the first time, the default is to embed.

How to insert video into PowerPoint 2010- from file- embedded or linked

Now, some very important data to help you choose which method to use- insert a 25 meg video that runs for 25 seconds- the video is embedded:

An embedded video in PowerPoint 2010- file size

1. Save the file with a 25 meg video and the result is a slight increase in file size.

2. Add some 3d effects and bevels to the video- the file size increases minutely. PowerPoint 2010 does not change the video at all, but holds a few lines of code internally to remember how to render the video with effects when displayed- either for editing or in a slideshow.

3. Trim the initial 20 seconds from the video (leaving the last 10 seconds) and the file size increases more- presumably PowerPoint 2010 keeps a record of the trimmed amount and attaches it to the saved presentation file.

4. Start again, compress the video (in BackStage) and the file size reduces to just over 20 meg. There was some scope to shrink the original video size.

5. Trim the video, and then compress, and the file size drops to just over 10 meg.

So- embedding a video will increase file size, but that can be reduced by compressing the embedded video or by trimming and compressing. Now to linking.

A linked video in PowerPoint 2010- file size

1. A 25 meg video linked within PowerPoint saves out at 52 kilobytes for the presentation- tiny!

2. Add the same bevel and 3d effects, and the file size increases slightly- again PowerPoint 2010 does not change the video at all, but holds a few lines of code internally to remember how to render the video with effects when displayed.

3. Trim 20 seconds from the video and save- file size goes up significantly. A possible reason was suggested to me at the Presentation Summit- that is-  a trim from the start of the file causes this- PowerPoint keeps start code for the video to ensure it can play. Well- I tested this and it looks like a  good theory! Trimming 20 seconds from the end of the video came out at 51.2 kilobytes!

4. Compress the original video is not possible- you cannot compress a linked file.

5. Compress a trimmed video is not possible- the file is linked.

Now, I'm not going to recommend what you do. But remember that if you do link, make sure you also have later access to the video!

Ensure your target computer can access your linked video file
