How to shrink WMV file sizes
Reducing video file sizes allows you to post your memories on the Internet. (video news cameraman image by itsallgood from

Video files are typically among the largest that you will encounter. Windows Media Video, also known as WMV, is designed to provide smaller file sizes with a minimum loss of quality. Sometimes, however, even these files are too large and must be further shrunk. By running your video through a converter such as Digital Media Converter or Any Video Converter, both available with a free trial, you can shrink your file size even further.

  1. 1

    Launch the converter program.

  2. 2

    Add the video files that you want to convert. This option will be either in the File menu or, in some programs, available as a point-and-click button on the main window. Most of these programs also allow you to convert other video formats, such as QuickTime and Flash, into WMV files.

  3. 3

    Access the video's settings, typically through the Tools > Properties menu.

  4. 4

    Select the output size and frame rate. Output size measures the height and width of your video in pixels. The frame rate determines how many pictures per second your video will be broken up into; for example, a movie in a theatre projects 24 still images every second. In general, the smaller output sizes and frame rates produce much smaller file sizes, but you will also sacrifice quality. You may have to try a few settings to find a balance that works for you.

  5. 5

    Click "OK" to accept the settings that you have chosen.

  6. 6

    Click "Save As" and give the file a unique name. If you are trying several sizes to see which one works best, number the files so that you can review each before making your decision.

Tips and warnings

  • If trying multiple versions, be careful to always select "Save As," not "Save," which will overwrite your last version.
