+    .DESCRIPTION
+        Users may add default values to the encoder.ini file if they do not
+        wish to set them manually each run with the -EncoderExtra option.
+        The values parsed from this file will be added to -EncoderExtra
+        automatically.
+    .PARAMETER Encoder
+        User selected encoder
+    .PARAMETER EncoderConfigFile
+        Location of encoder configuration file. Default is ../../../config/encoder.ini
+    .PARAMETER FFMpegConfigFile
+        Location of ffmpeg configuration file. Default is ../../../config/ffmpeg.ini
