I’ve written about this before, but it’s something that gets asked a lot when I am doing IWB training, so I thought it was worth flagging up again.
If you want to make screen grabs from some Windows Media videos, you may find you get a black box rather than the screen shot you were expecting. To make the computer render the video so that you can actually capture images from it, you need to make a quick change to the video player settings. Once done, you shouldn’t need to change it again (hopefully).
I’ve produced a short worksheet which I have uploaded to Scribd, hope it’s useful.
You could also watch the video demonstration of this here.
