This trick only works if you have Microsoft Expression Encoder installed, and PowerShell. Load the Encoder assembly, construct a new MediaItem, and pass the first file in the directory ((dir)[0].FullName) as the constructor argument.
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.Expression.Encoder")
$media = New-Object -TypeName Microsoft.Expression.Encoder.MediaItem (dir)[0].FullName
After creating the object, you can look at all the properties easily, or look at specific ones.
$media $media.FileType $media.MaxBitRate $media.VideoSize
