When it comes to the simplest way to combine clips to create a movie with titles, background music, transitions, and effects, Windows Movie Maker has been a top choice of video editors. Now, more and more people like to create a WMV video in Windows Movie Maker. Theoretically speaking, WMV in high quality gives more clarity, more bits to show the image, and more bits means a bigger file size. That is to say, WMV can simply be interpreted as big file size. So there come some conflicts, for example:

"I have created a WMV file that looks pretty good but it's about 7 meg which is too big to email. When I save it in email format, the video and audio go to ^$*&. Is there any way to compress WMV file for emailing and uploading to websites, or what do I need to do?"

As we all know, large WMV files are slow to upload and download. To make WMV uploading and downloading process quickly completed, the best solution is to compress video file size. So is there any free ways to compress WMV file to smaller size? Yes, of course there is. Just follow the tutorial below to learn how to compress WMV file with free way.

Top Methods to Compress WMV File

Method 1: Compress WMV File to small sized MP4

Generally, we can compress WMV file to FLV to achieve smaller video size, especially when you need to upload WMV video to YouTube. What's more, you can also compress WMV to MP4 because MP4 takes up less space than WMV when provides same video quality. MP4 also makes good compatibiity with most devices and video sharing websites.

Method 2: Change WMV profile parameters

The video file size largely depends on these profile parameters listed below. You can also shrink WMV file size by adjusting video profile parameters.

Video resolution: The higher the resolution, the clearer the picture. However, the higher the resolution, the larger the file size will be. Changing the original video to a smaller resolution will lead to a smaller file size. For WMV video with a file resolution of 1920×1080, it's recommended to reduce to 640×480, 640×360, and more resolutions. 

Bit rate: As for the bit rate, lowering the bit rate will bring about the decrease of the video file size. But please keep in mind the image quality will be bad in case you make the bit rate too low. 

Frame rate: The frame rate has a significant impact on the file size. Lowering the frame rate of your video to 15 or 10 fps can reduce the file size by as much as 1/2 or 2/3. However, reducing the frame rate may affect the smoothness of the playback. Acceptable frame rates vary depending on the specific video clip. You may have to experiment to find the lowest acceptable value.

Method 3: Trim/Crop WMV files to remove unwanted parts or areas

Trimming or cropping WMV files is another simple but effective way to compress WMV files without quality loss. Trim your unwanted segments from the WMV video to leave only your desired parts. Crop the black bars around the WMV video frame to play the video with full screen.
