CW18 - Mini-workshop Screen Recording Guide

The rooms that will host the mini-workshops and demos sessions don't have any screen capture system. We encourage mini-workshops and demos sessions speakers to capture their screen and record their audio, such that we can publish the video on our YouTube channel and associate it with CW18.

Audio Record

We will provide USB Jabra microphones for those that would like to capture their activity.
