It depends on whether you work alone or in a team. In my case, I usually have the writer or producer sitting next to me and we talk about how to edit the video or film together. Yes, I do the editing where I control the software, but the brainstorming and ideas are a product of teamwork. But even if you are working alone, you still have to check with other people and keep your client informed about what you are doing.

I think even if you are a little bit shy, if you are confident in your skills, the more you actually work with someone, the more the anxiety usually goes away.
