Windows Media Video (WMV) is a video format and is a part of Advanced Systems Format (asf) container. Microsoft developed this format. WMV 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.

The exclusive codecs developed by Microsoft can be obtained while a WMV file is compressed. Users can use Windows Media Video 9 Professional. 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. It does not support various activities, such as multiple reference frames and context-adaptive binary arithmetic coding (CABAC). Lower bit-rates can reveal the differences between WMV and its competitors.

Apple QuickTime Player

The M4V format was developed by Apple for Itunes Store and it is much more similar to the MP4 format with a slight difference in DRM protection. If M4V format has DRM protection than the iTunes account used to process the file will have to be authenticated on the computer playing the file.

The M4V supported files have both the audio as well as the video data, the file extension M4V can be converted into the MP4 file extension in order for it to play on an unauthenticated computer because the M4V files are protected by Apple’s DRM. MP4 files do not provide with the functionality to create chapter information while M4V file does that.
