Setting for Webinars

When people witness a well-run webinar, they may not realize the behind-the-scenes setup and logistics it takes.

This setup is configured to facilitate a 3-day highly engaging webinar. It involves everything we advise in our 1 or 2-day High Impact Presentation Skills webinars where we tell participants to use a professional background, external webcam, mic, good lighting, and so on.
The setting may change when I deliver 30 – 90 minutes keynotes virtually. I may stand, use an external camera, and use a different background.
What about your setting?
