What is WMV?

WMV stands for Windows Media Video — developed and controlled by Microsoft. WMV is a generic name of Microsoft’s video encoding solutions and doesn’t necessarily define the technology what it uses — since version 7 (WMV7) Microsoft has used its own flavour of MPEG-4 video encoding technology. DivX video format is originally based on hacked WMV codec.

Windows Media Format 11 adds support for HD video up to 1080P. WMF 11 runs only on Windows XP and Vista.

Additional information is available on Microsoft Windows Media page.

What is GIF?

Animated GIF is not really a video format. It is a sequence of GIF frames stringed together. Due to the 256-color limitation of GIF, the color is dithered. The compression is not that great, so the file size tend to be large given the frame rate and resolution.

However, since GIF is supported by all web browsers without any add-on, it is a great way to create small video thumbnails. Generally, the resolution should be kept small (80×60, for example), the frame rate should be kept low (4 fps, for example), and the duration should be kept under a few seconds.

Animated GIF is not really a video format. It uses 256-color GIF compression, with low quality and relatively large files. It is not suitable for video playback. However, since it is supported by all web browsers without any add-on’s, it is a great format for video thumbnails and should be used for this purpose only.

To encode a video to an animated GIF, you need to have River Past Animated GIF Booster Pack in addition to the video software.

Additional Requirements

To convert from WMV(Windows Media Video) to GIF(Animated GIF) video with River Past Video Cleaner, you must have River Past Animated GIF Booster Pack installed.

Add File
Click on the “Add” button on the tool bar. The standard file open dialog appears. Select “WMV – Windows Media Video” in its “Files of type” combo box.

Select the file you want to convert and click “Open”. The file will be added to the conversion file list.

Use the setting panel on the bottom of the window to control the output format. Click on the toggle to the left of the “Output Format” label to expand the panel. Select “Animated GIF” as the “File Type”.

Note: To convert to animated GIF files, you must have River Past GIF/FLC Animation Booster Pack installed.

Change Video Settings

You can change the size, and frame rate of the video.

Animated GIF is NOT a video format and is not designed for video playback. It is limited to 256 colors, so the video will be dithered. GIF compression is designed for solid color graphics, so it is not very efficient for video. The resulted animated GIF files are normally much larger than the original video file, given the same resolution and frame rate.

For the above reasons, it is not a good idea to use animated GIF to share your video on the web. Instead, it is an excellent way to display a small moving thumbnail for the link to your video. For this purpose, you should specify the size to around 80 x 60, and frame rate to 2 frames per second for the best result.

Select output directory
Expand the “Output Directory” panel. Use the “Browse” button to select an output directory.

Convert
Click the “Convert” button on the tool bar, and it’s done!.
