Question 3

A student's online music lesson video has a flickering background light. What camera setting should the teacher recommend adjusting first?

Accepted Answer

Match shutter speed to room's lighting frequency (e.g., 1/50 or 1/60)

Fluorescent and LED lights flicker at the electrical grid frequency (50 or 60 Hz), and matching the shutter speed to that frequency eliminates the flicker effect in video.

Question 4

Which type of microphone pickup pattern is best for isolating a single vocalist while rejecting sound from the sides and rear?
