A WMV file is a video storage format that Microsoft developed for use with their Windows line of operating systems. The format is designed to allow high-definition video quality while maintaining a small file size by using some clever compression techniques.
Also known as Windows Media Video files, WMV files became somewhat of a standard format for video files due to the popularity of Microsoft's operating systems. With built-in support for WMV playback also appearing on other platforms.
WMV files, although still popular and supported by a wide range of video editing applications and video players, have largely been replaced by other, more capable formats, such as MP4.

The AVIF file format is aimed at being a modern replacement for the popular JPEG image format. Developed by the Alliance for Open Media, AVIF is an advanced image file format that leverages the cutting-edge compression algorithms used by the AV1 video codec.
The aim of the format is to surpass the quality of the equivalent JPEG file while packing a smaller file size via the use of the AV1 compression algorithm. The aim of the compression algorithm, which is a lossy algorithm, is to reduce the file size by removing detail from the image that the eye would not normally notice, thus reducing the size of the final AVIF file.
Support for AVIF files is still growing, with many modern image editors able to read and write to the format. The latest versions of the most popular web browsers have also moved to support AVIF images, having seen the benefit to website developers of reduced image sizes and thus reduced bandwidth usage.
