Here's a statement that may seem controversial:

"When making videos, sound is more important than picture."

Studies show that while people will tolerate the worst quality video images, they will not watch programs that have poor quality audio. If you aren't convinced, look at this this way: nearly all of us have enjoyed television without actively watching the pictures (while cooking, for example); but no one can tolerate even a minute of TV viewing with the sound muted.

Similarly, many students are surprised to learn that it is not uncommon for a television production company to spend more time working on the audio portion of a TV program than the video portion. At any given point in a show, for example, there is only one visual image on screen. But at that same moment there may be dozens of audio tracks all dancing together: dialogue, music, sound effects etc. Each audio track must be carefully created and adjusted to within very precise tolerances to produce the desired effect.
