Getting better audio for your video!

Hi everyone,
I can't say that this would apply across the board, as everyone's cameras are a little different. Having said that, one thing that people might not be aware of is something called auto or manual setting in the audio menu. If you have the option available in your camera menu- choose manual. I'll try to explain why..
When the audio levels are set to auto, then your camera tries to normalize the sound it is hearing (make it all the same level for playback). It basically 'chases' the sound and increases and decreases the input volume depending on what sound it is hearing. When there is loud sound- the auto level LOWERS its input level. When there is very little, or no sound- the auto level INCREASES its input level to try to find sound. That's when you get the hiss. You'll probably notice the hiss disappears or becomes less noticeable as other sound increases. That's your auto level doing its thing.
Manual levels let you set a level that you're happy with- period. You basically play your loudest strum, and set your levels to that. The level will not change/chase the sound. Quiet playing will be quiet- and hopefully have less noise as well. Sometimes there will be an audio meter display on your camera as well. There should be a marker of where most of your notes should hit. They don't all have to be there- but that's your general guide.
This won't be available on all video cameras- and probably not on ANY still cameras that let you record video- but if you're lucky enough to have this option, I would suggest you use it. Your webcam/computer might have this option as well. Worth looking into.
Hope this helps some people.
