"Scripts Commands".
5Modify the values of the metadata you want to edit.
6Once you finished editing the metadata, re-encode your recording.
7Open the Expression Encoder Output folder (this folder is in the Merger
folder). Delete the file named media.wmv and rename the file named
SLVideo_media.wmv into media.wmv.
Using the Mark in/Mark Out Feature in Expression Encoder
Using the Mark In and Mark Out Events requires modifications to the timeline
in Expression Encoder. The steps below illustrate how to use the Mark In and
Mark Out points to create a video for the Polycom Rich Experience Player to
include only the portions of the video the presenter has specified. This process
can be handled by someone with basic video editing knowledge.
