Inserting flv video into PowerPoint
There are several programs which allow you to view Flash Video. One example is VLC Media Player, which is free and can be downloaded at http://www.videolan.org.
To insert flv video into PowerPoint, one way is to make use of the VLC Media Player.
First, install the VLC Media Player.
Once done, create a folder.
Move the presentation and flv video to the folder.
Now, open the presentation.
Go to the slide which you want to have the Flash Video inserted.
You will need the control toolbox to be displayed.
Click View > Toolbars > Control Toolbox.
On the toolbar, click on the last icon which should be “More Controls”. (For PowerPoint 2007, Click Developer tab. Under Controls, click on the icon “More Controls”.)
Scroll right to the bottom and look for VideoLAN VLC ActiveX Plugin (both v1 and v2 is fine).
Click Ok.
Now, right click on the control that has been added, select Properties.
This will bring up the properties dialog box.
Under MRL, enter the filename (e.g. abc.flv).
Once done, close the dialog box.
