A shotgun microphone features directional polar pattern such as cardioid and supercardioid with a barrel shape. It is useful in film and TV production to pick up on-axis sounds and reject sounds from the sides and rear. You can use this microphone for filming in two ways. One is to mount it on the cameras, so it can move with the DSLR and record on-camera talents. The other is to attach it to the boom pole. With a boom operator, it can stay close to the subjects while keeping out of frame. A shock mount comes to help reduce the handling noise when the boom is moving.

Omnidirectional mics, on the other hand, are ideal for studio settings. Manufacturers have designed them to be so adaptable that they can collect sound from the talents as well as the background. If you need to pick up the room tone and minor audio signals, omnidirectional mics are a suitable choice. They can provide you with flawless audio synchronization in the final product.
