Video Screenshots
One of the really useful features of most IWB software is the ability to be able to take screenshots from videos and use them in your presentations. Both Smart Notebook and ActivStudio have a camera tool that allows quick screenshots to be made.
This can also be done using the Print Screen button on any computer and then pasting the resulting image into Word or Powerpoint.
One issue I often come across when demonstrating this to teachers is that instead of a picture from the video they get a black box instead. This mainly happens with avi or mpg files that open in Windows Media Player. Quicktime videos seem to work OK all the time.
There is a setting in Windows Media Player that you need to change to be able to take screen grabs. It's pretty straightforward, and once done should not need to be done again.
Firstly - open up a video file and right click on the icon in the bottom left corner of the window (It may look like a small thumbnail of the video):

From the menu that appears, choose Tools > Options

From the tabs at the top of the window, click on Performance and then the Advanced button.

From the window that appears, find the option for Use Video Mixing Renderer and click in the box next to Use Overlays to remove the tick.

Then click on OK a few times. When it asks you if you want to continue with the change click on Yes.

The video should now be able to be captured using either the Camera tool in the IWB software you are using, or with the Print Screen button (and then paste into whatever application you are using)
I have also created a Video Tutorial to show you how to do this. Apologies if the sound is a little quiet.
Hope this helps!

This does have an effect on performance, video overlays are put on by the graphics card, so the video doesn't have to be rendered by the core system. That's why they don't show up in screen captures but also means the video rendering isn't hogging a lot of CPU. I'd suggest turning overlays back on after taking your screen shot, especially if you have any playback issues.
Thanks Thom. I knew there must be a reason why it's the default setting. It's annoying to have to change each time though.
Thankfully many websites are now using the Flash video format which can easily be captured as screenshots - YouTube and BBC iPlayer for example.
thanks for the info. i always faced problem in taking screen shots from windows media player.
Thanks Danny, I've spent many a frustrated hour trying to capture a video clip. Something new to try.
I agree, I have also spent many hours of frustration trying to do this. Thanks for the tips, from all!
