Compatibility of Video Attachments Created Using Microsoft Test Runner in Visual Studio 2010
In Visual Studio 2012, Microsoft Test Runner creates videos in Windows Media Video (WMV) format. For compatibility with videos created using Visual Studio 2010, you must install the Expression Encoder 4.0 diagnostic data adapter software. This will allow you to view video attachments created in Visual Studio 2010 using Visual Studio 2012. For more information about which software to install, see the Visual Studio 2010 topic How to: Install the Required Software to Create a Video Recording Using Test Runner.
