Audio is one of the most frequently over looked, but one of the most important parts of a video for YouTube. Almost anybody can post a video online now but one thing that will help that video stand alone in the crowd is high quality audio. When squaring audio there are 3 main things to consider; audio source, audio levels and ambient noise.

The most important thing to consider when recording audio for video is the audio source. Be it a built in microphone, an external microphone or a feed from a mixer the source will be the biggest determining factor of audio quality.

Almost every video camera has a built in microphone, and almost every built in microphone will produce sub-par audio. The audio from a built in microphone will often pick up the noise from the camera itself, the noise made by operating the camera and not to mention they are not usually very direction so they pick up a lot of ambient noise.

If there is no other option but to use the built in microphone the best solution is to get close to what ever audio is being recorded. If it is a person speaking, zoom out and move the camera closer to the person. If it is the sound of a saw cutting, again zoom out and move it. The closer the microphone is the better the audio will be.

An external microphone will almost always give better audio quality than a built in microphone. Many video cameras will have an external audio jack that will either be a stereo mini jack or XLR plugs on high-end cameras. Almost all microphones will work with any camera that has a microphone jack, either directly or with the use of adapters.

When interviewing a person, or having a person speak to camera a lav microphone will help eliminate unwanted noise by putting the microphone very close to the persons mouth. This is how all TV News and Sports anchors audio is captured.

When working in noisy areas or performing on the street interviews a stick mic will often be the best choice. Stick mics are what you will often see on-sceen reporters using with a mic flag that shows what station they work for. This type of microphone is good at eliminating unwanted noises and is easy for a person to point back and forth from themselves to another person.
