To provide a bit of background, my company does both technical projects and "teaching projects" in which someone from my company goes to another to teach them how to use certain technology, framework, and so on.

I am a Software Engineer with another fancy title, basically I develop what I am told, and more recently also give (small?) lectures.

Recently I have been tasked with giving classes, which I was reluctant but since it is something I was told when I joined, I was ready for it, and I have tried my best.

Now all of a sudden (they basically have not told me until I have no other choice), for the current classes I am giving I am required to also record myself doing a summary of what was seen on the class.

Thing is, they already telling me that I should make the video as neutral as possible, so it can reused as needed in the future.

I am usually a shy person and even with friends I try to sneak out of photos, just goes with how I am. I feel like this falls out of my obligations, and I get nothing from going so far out of comfort zone, so I am not only incredibly nervous but also wondering how hard should (can) I refuse.

Not sure if anyone has been in this situation but I could really use some advice. They are trying to selling it to me in a "it will improve your visibility" and that kind of empty phrases, so all in all I feel I am very negative and close to have a mental block where I simply refuse (which is what I want to do).

I do not want to say out loud that I consider quitting the job over this, but I do have to fight that impulse, that big of an issue is for me personally.

Update:

After talks with a couple of managers, it seems it would now be enough with just recording my voice. For them it seems like very different issues, prior it was both video and voice, now being only voice, it appears to not be the same issue.

To me the problem still exists, but I am still going to process it and cool down to check whether or not it is.
