Will Curran from Endless Events is a fountain of knowledge when it comes to all things AV. As even more of a god-send, his specialty is (as the company's name would suggest) events.
The four types he suggests are:
- The pre-show video
- A countdown video
- A video to build anticipation and
- Introduction videos.
He also suggests that conference organisers use "coming next" and recap videos to add to the experience.
For full details of how to structure these videos, as well as the reasons for using them, you can watch the full video by the team at Endless Events or read the transcript here: https://helloendless.com/video-at-conferences
