b> Windows Media Player is a dynamic media player that comes included with Windows operating system.
According to the Microsoft website, Windows Media Player 12 plays nearly every video format, including 3GP, AAC, AVCHD, MPEG-4, WMV, WMA, and most AVI, DivX, MOV, and Xvid. So, before you begin, you may want to be sure you have the most up-to-date version.
Open the file in Windows Media Player. If it is not the default player on videos, simply right-click on the file, select "Open With" and choose Windows Media Player. Pause the video on a clear frame. Windows Media Player will begin playing the video automatically, so you just need to pause it on a frame that you think you will be able to use as a template for the rest of the movie. Access the Now Playing menu (this is in the upper left-hand corner). Click on it to pull down more options. Select "Video Settings" from the Enhancements submenu. This will open up a small panel at the bottom of the window with various image adjustment meters. Slide the "Brightness" control a little to the left to brighten the image. The image will stay the same until you press "Play," at which point you can view the effects of the new settings. Repeat Step 5 until you find the right brightness. Close the Video Settings menu by pressing the red "X" in the upper right-hand corner of the menu screen. http://windows.microsoft.com/en-US/windows7/products/features/windows-media-player-12
b> Brightening the video may give the image a bit of a "washed out" look. Remedy this by tinkering with some of the other settings in the menu. Increasing the Saturation often helps with this problem.
