You do not need a studio in Defence to start. A quiet room in Johar Town, a USB microphone, and a light that does not flicker on camera will already look more serious than a phone propped on a stack of books.
Start with audio. A simple USB mic on a boom arm beats laptop mics and most “gaming headset” voice chats. Keep the mic a hand’s width from your mouth and turn the gain down until the room noise drops.
Then fix what the camera sees. A ring light or a small key light in front of you, slightly above eye level, is enough for talking-head videos and unboxings.
