WMV files are a type of video file (usually containing audio) from Microsoft. These files can be played on a variety of video players on both Mac and PC machines. Some WMV files may have digital rights management (DRM) protection which prevents users from making unauthorized copies of files purchased in online stores.
These are the types of video files which in reality only contain the audio and this format was also developed by the Microsoft. These files can be facilitated by a variety of Operating Systems such as Mac as well as the PC. A few WMV files also have the digits right management (DRM) protection so unauthorized can't make copies of the recordings basically the ones purchased from an online store.
Windows Media Video (WMV) is a compressed video file format for several proprietary codecs developed by Microsoft. These files are based on the Microsoft Advanced Systems Format (ASF) container format encoded using the Windows Media Video (WMV) codec.
The exclusive codecs developed by Microsoft can be obtained while a WMV file is compressed. Windows Media Video 9 Professional can be used by the users and it allows them to play their respective file at resolutions surpassing 300,000 pixels (having a screen resolution as low as 528x576) with an exceptional bit rate of 1000 Kbit/s. The high definition abilities make WMV files an ideal choice for HD DVD and Blu-ray disks. WMV 9 format is the one you should be looking for and it is also comparable to H.264 Main and High Profile, but it does not support various activities such as multiple reference frames and context-adaptive binary arithmetic coding (CABAC). Lower bit-rates can reveal the various differences between WMV and its competitors.
Similar to the MKV file extension, WEBM is a file format developed by a number of parties, including Google. Launched in 2010, it is open source format designed to deliver video through the web. It can be used for a variety of types of video, from video calls to high definition movies. WebM is growing, and by using the HTML5 version of YouTube, it is possible to watch video encoded in WebM.
Like the MKV file extension, the WEBM extension is developed by various online parties such as Google, it is a freeware offering streaming of online video content and it was first developed in 2010. By using the HTML5 version of YouTube one can watch video encoded in WEBM.
WebM benefits from being designed for use on the modern web, rather than for local use. This means the format is specifically designed for the wide range of devices that are used to access the web, from Smart Phones to Powerful PCs. The video element of the file is encoded using VP8 video codec and the audio element of the file is encoded using the Vorbis audio codec.
Encoding and deciding in WEBM format is possible while using the ffvp8 software or libvpx from the Google support. When it comes to the Android support a version of 2.3 (Gingerbread) and above allowing playback of WEBM format can be used for encoding and decoding. Back in 2001 using Rockchip a full hardware implementation of 1080p VO8 encoding was made possible.
