Instead of uploading a new video, rich media recording you can also create virtual asset based on an existing video. This can be an internal or external (YouTube/Vimeo etc.) video. Like normal assets you can fully describe the asset will all available metadata.
Internal videos can be virtual cut (trimmed) using segments.
Make sure external sources are publicly (open/freely) available when adding them as virtual asset. Since the video content will not be imported, only made available for search and description in the Presentations2Go video server.
