.XEL File Extension
File TypeExpression Encoder Live Encoding File
What is a XEL file?
Settings file created by Expression Encoder, a video transcoding application included with Microsoft Expression Studio; stores the presets for a live video encoding session and includes references to the source media as well as the transcoding settings for each file; saved in an XML format.
Live encodings are performed while video is streaming. For example, a XEL file can save settings for encoding a live webcast into a video stream or file. Live encodings differ from encoding jobs, which are saved in the .XEJ format.
NOTE: Expression Encoder is available for free or as part of Microsoft Expression Studio.
