This codec also supports professional-quality downloadable video with two-pass and variable bit rate VBR encoding. Windows Media Video 9 is already supported by a wide variety of players and devices.
Content creators can use this profile to deliver either progressive or interlaced content at data rates as low as one-third that of the MPEG-2 codec—with the same quality as MPEG In the past, interlaced video content was always de-interlaced before encoding with the Windows Media Video codec. Now, encoding applications such as Windows Media 9 Series, and third-party encoding solutions can support compression of interlaced content without first converting it to progressive content.
Maintaining interlacing in an encoded file is important if the content is ever rendered on an interlaced display, such as a television. Transport independence also enables the delivery of Windows Media Video 9 Advanced Profile over systems that are not Windows Media-based, such as standards-based broadcast infrastructures through native MPEG-2 transport streams , wireless infrastructures using real-time transfer protocol [RTP] , or even DVDs.
The following table compares Windows Media Video 9 Advanced Profile to competing compression technology. The Windows Media Video 9 Screen codec is optimized for compressing sequential screen shots and highly static video that is captured from the computer display, which makes it ideal for delivering demos or demonstrating computer use for training.
The codec takes advantage of the typical image simplicity and relative lack of motion to achieve a very high compression ratio. During the encoding process, the codec automatically switches between lossy and lossless encoding modes, depending on the complexity of the video data. For complex data, the lossless mode preserves an exact copy of the data. For less complex data, the lossy mode discards some data to achieve a higher compression ratio. By automatically switching between these two modes, the codec maintains video quality while maximizing compression.
Overall, the Windows Media Video 9 Screen codec delivers better handling of bitmap images and screen motion, even on relatively modest CPUs. It is also up to times more efficient than the commonly-used run length encoding. Instead of processing uncompressed video, it transforms still images into video by using pan, zoom, and cross-fade transitions between clips to create an unlimited number of effects. The results can then be delivered at data rates as low as 20 kilobits per second Kbps.
The following table outlines what your audience will experience when playing Windows Media Video 9 Series content on earlier Microsoft Windows operating systems or with earlier versions of Windows Media Player. What is Windows Media Player 12? What are the key features of Windows Media Player 12? Easy to use: Windows Media Player is the default multimedia player for Windows. It comes with a simple and straightforward user interface.
Thanks to this application, viewing or listening to files saved on your computer or external storage devices becomes a piece of cake. Manage your media library: This player allows you to sort your music in your very own media library based on different criteria, such as song title, album, artist, date, musical genre, etc.
You will also be able to edit the metadata and see the covers of your albums. Create playlists: Windows Media Player 12 offers you the possibility of creating your own custom playlists from the media files available in your library and the local folders on your device.
It's installation deploys the Windows Media Codecs to your computer, fixing the eventual errors generated by previously installed codec packs. It's original goal was to compete against the Internet streaming monopoly-owner RealVideo. Thus, if you didn't install Windows Media Player, you may stumble upon videos on the Internet that won't play. Windows Media Player 9 Codecs Pack consists of several codecs that help your computer encode and decode audio and video streams automatically or on user demand.
It enables the application to receive media streams both locally, across networks and the Internet.
