What is WMV?

WMV, short for Windows Media Video, is a video compression format developed by Microsoft. It is a highly compressed format used for streaming video content over the internet and for storing video on local devices. A WMV file is compatible with Windows Media Player and can be played on many other media players as well. The WMV format supports various video resolutions and bitrates, making it a versatile option for video content creators and consumers.

What is MP4?

MP4 is a digital multimedia file format developed by the Moving Picture Experts Group (MPEG), which stores video, audio, and other types of media content. It is a widely used file format for sharing and streaming video content over the internet and is supported by a wide range of devices and media players, including smartphones, tablets, computers, and smart TVs. MP4 files can also support other codecs and features, such as subtitles, multiple audio tracks, and chapter markers, making it a versatile and popular format for multimedia content distribution.

WMV or MP4, which one is better?

Features AVI MP4 Conclusion
Quality For a WMV file, its video uses WMV encoding while its audio adopts Windows Media Audio encoding. Moreover, WMV has a high compression ratio. However, as it still emphasizes the PC display rather than the mobile demonstration, the image is clear enough. MP4 usually adopts various compression codecs for encoding, so its output quality can also be guaranteed at an excellent level. WMV quality would be slightly higher than MP4.
File Size WMV primarily uses H.264 and H.265 codecs. Hence, its compression algorithms are relatively lower in technology than those in MP4. MP4 typically uses more advanced video compression algorithms than AVI, like H264/MPEG-4, HEVC, MPEG-1, VP8, VP9, etc. MP4 is a little bit smaller than WMV.
Compatibility WMV is a relatively old-fashioned format nowadays. Although it can still be playable by many players, it is compatible with the Windows system. MP4 is more compatible with different platforms and devices. It is an industry-wide standard for Windows, Mac, Linux, iOS, and Android systems. MP4 boasts stronger compatibility.
