WMP 6.4 (the last version for Windows NT 4.0) also isn't reliable with VBR-encoded content. However, none of the pre-WMP 9 versions support the full Intelligent Streaming model implemented in the current version of WMS, and hence can only switch between video tracks of the same frame size, and not at all between audio tracks. Older versions of WMP can use WMV 9 and WMA 9 using codec updates (either automatically downloaded, or via an enterprise deployment). WMP 10 was a fine release, but was focused more on performance and media management, and didn't add much functionality specific to web video. It can safely use WMV 9 and all the WMA 9 audio codecs. WMP 9 established much of the modern infrastructure for Windows Media, and it's functionally equivalent to WMP 11 for almost all web video.

WMP 9 is preinstalled with the widely deployed Windows XP Service Pack 2, and it is available via Windows update all the way back to Windows 98. WMP 9 is a good baseline target for mass-market WMV delivery today. With WMP, you can safely use both WMV 9 Advanced profile and WMA 10 Pro's LBR modes.

It's available as a free download for Windows XP and built into Windows Vista. Windows Media Player 11 is the newest version of WMP. It works best when targeting WMP 9 or higher running on Windows. Also, not all clients support Intelligent Streaming. Files that won't be coming off WMS should not be encoded with Intelligent Streaming, since it'll just make the files larger, but won't provide any added functionality. Intelligent Streaming is only available when doing real-time streaming from WMS with Windows 2003 Server. Then the player and Windows Media Services (WMS) cooperate to determine the highest data rate version of the video and audio that will fit within the available bandwidth. The idea behind MBR is to provide content in multiple bit rates in a single file in order to provide scalability in streaming. Intelligent Streaming is Microsoft's name for our multiple bit rate (MBR) encoding system. The slowest mode is a lot slower and very rarely produces any measurable improvement in quality.

In Windows Media Encoder, it is set in Tools > Options > Performance.For optimal quality, the second-to-slowest mode (listed as "4" or "80" in some tools, and second last to the left in WME) is almost always the best choice. Different tools present the option in different ways. There are six levels in the v11 codecs with about an eight-fold difference in encoding speed from slowest to fastest, and about a 20% improvement in compression efficiency from fastest to best (which actually isn't the slowest). Best Practices for Windows Media EncodingĮncoder complexity controls how hard the encoder works to encode the video.
