Preparing to work with sound effects SFX's

1. The reason why we use SFX's in TV & Film productions is because we want to make stuff more excitable to watch for example HollyWood films use SFX is car explosions and car crashes to make the scene have a big impact from watching it from the screen, they also use gun shots and fire sounds to make it more intense. TV use SFX to make more sounds realistic for example a Soap programmes might add in a car skids SFX to emphasise the car skidding in motion.
2.Advantages; Cheaper, making something that has no sound to making something special and captures alot of viewers.They add more SFX's make the view feel more in-depth with the film or Tv programme.
3. Disadvantages; knowing that scene has been adding with SFX which makes it unrealistic,  it doesnt work in some scenes , sometimes its overused and doesn't seem to work with scenes and your can see some lip-sync erros.
