No, as I mentioned free available videos on the internet.
As they are available there free and doing the rounds on the social media frequently, therefore in this context I asked that if they be used on udemy with my voice over instructions?
Hey @ShashankShekhar, if you think that the material that you are using might be infringing upon somebody else's idea or content, we would suggest not including it in your course. The easiest way to check whether it is ok for you to use somebody else's content in your course is to contact them directly and ask for their permission.
