If you want to begin altering the settings for video capture you go to File in the upper task bar and choose “Capture Video. You can also start by going to the Movie Tasks side bar and selecting “Capture from video device” from under the Capture Video heading. If you do not have a capture card on your computer, you will be informed of this and will not be able to continue with this process in Windows Movie Maker.
Once the Video Capture Device page is open, you can look to the Available Devices list to find your capture card. There will likely only be one item here that will actually be able to be of use, unless you have a variety of different capture cards as with a professional editing system. Find the one you want to use, select it, and choose Configure.
When looking at the Configure Video Capture Device window, go ahead and select Video Settings. Now, you will be able to make changes to the way the video is captured from the available options. There are a number of these, including things like the overall size of the video display. It is important to remember that the degree of choice you have are limited by your computer, your capture card and the software you have with your capture card.
