Hi Sarah…. I’m going to guess you are referring to the Encounters videos? When I made those, I did not realize the mic on the headset was not setup correctly and what you hear is the mic on the laptop picking up my talking from a distance. I plan on redoing the videos soon. The Celestial Reloaded videos are much better once I found out what was happening.
In the meantime, there are some Encounters video tutorials that are similar to the Celestial Reloaded and Luminescence videos, so there might be a few that you can watch from the others.
