Hi @G.Yuvaraj, just adding to @Mobile_Faculty's already fantastic advice.
I recommend checking this help article. Some of our best instructors are here sharing their tips on the video creation process, and it's a very useful resource for new instructors looking for the best way to record their videos.
Also, feel free to browse around our A/V Solutions section, this is a great place to learn more about how to achieve good quality audio and visual setup.
