How to Shorten a Video with Media Player
Windows Media Player is the media player application that is native to the Windows software suite. Microsoft developed the program to open and stream digital media files. While Windows Media Player is not equipped with any editing or encoding capabilities, you can override the application's default settings to shorten video playback. This is a simple process that requires just a few mouse clicks. Windows Media Player supports the following digital video formats: WMV, WM, ASF, AVI and MPG.
Click "Start" and "All Programs." Select Windows Media Player from the list of applications to launch the program.
Click the "File" tab on the Windows Media Player program menu, and select "Open..." Browse for the video in the file selection window. Select the item, and click "Open" to load the file into the application.
Click the "Play" tab, and select "Play Speed." Choose "Fast" from the fly-out menu.
Click "Play" to stream the shortened video. The accelerated playback speed will shorten the clip's original running time by about 30 percent.
Close Windows Media Player by clicking the "File" tab and selecting "Exit."
