WMV Codec

Windows Media Video, or WMV, is Microsoft’s family of video codecs including WMV 7, WMV 8, and WMV 9. The WMV codec can handle anything from low resolution video for dial-up Internet users to HDTV.  The latest generation of WMV, based on the WMV 9 codec, has been standardized and approved as a new and more open codec known as VC-1.  While all versions of WMV support variable bit rate, average bit rate, and constant bit rate, WMV 9 introduced several important features including native support for interlaced video, non-square pixels, and frame interpolation.

+ Use our transcoding software web UI, located @ http://www.encoding.com/login, to designate an Amazon S3, Rackspace CloudFiles or FTP site to use as your watchfolder. Turn an entire folder of content into WMV files. All you have to do is select 'Add Task' and apply a WMV preset from the dropdown menu in the watchfolder UI. Need just Windows Media Audio, we have a preset for that as well!

+ Upload a single piece of media with our 'Add Media' feature in the web UI. Select 'Add Task' and apply an WMV preset to your encoding workflow from the dropdown menu.  As with watchfolders, 'Add Media' can source from Amazon S3, Rackspace CloudFiles, FTP sites or your local drive / network.

+ Implement our powerful API to submit source content and create WMVs in a snap. Complete API documentation here

Don't forget to take a peek at our sample XML template for WMV creation.
