WMV Compressor

You may need to compress WMV video for many different reasons - to save space in the device's memory or to transfer a file over the Internet. In any case, you need a good compressor that will do its job at the highest level. Modern video compression algorithms differ from image compression algorithms with which you may be familiar. The extra dimension and time means that various mathematical and logical methods are applied to the video file to reduce the size while maintaining the video quality. Video compression algorithms look for spatial and temporal redundancy. By encoding redundant data a minimum number of times, the file size can be reduced. Imagine, for example, one minute as the character's face slowly changes its facial expression. It doesn't make sense to encode a background image for each frame: instead, you can encode it once and then refer to it until you know the video is changing. This inter-prediction coding is responsible for artifacts that interfere with the compression of digital video: parts of the old image move with the wrong action because something in the coding has become useless.

The abbreviation WMV stands for Windows Media Video. A similar extension can be seen in video files - you need a player that supports this format to view them. Video format wmv (Windows Media Video) - the format was born thanks to Microsoft. A video file based on the Microsoft Advanced Systems Format (ASF) container format and compressed using Windows Media Compression. It is similar to the .ASF file and contains video encoded using one of Microsoft's native Windows Media Video (WMV) codecs. It contains audio, video, or mixed recordings packed using the Windows Media Audio codecs (WMA is a special kind of format designed exclusively for storing audio files) and Windows Media Video (WMV). It was developed mainly for storage and possible broadcast of video information. In addition to Windows, this format is also supported by other operating systems, if the appropriate codecs are installed. Also, WMV has become widespread among portable playback devices. Almost all computers should play this format, since codecs for WMV are usually installed with Windows, so such files should be opened by many players. When choosing a suitable program, you need to be guided by the ease of use and the availability of additional functions.
