I have a video on youtube of me playing bass. All it has is a digital camera recording me. The visual quality is pretty good, sound on the other hand is just eh...

Does anyone have a good suggestion on any kind of programs, camera, plugs, etc... on what to use?

My digital camera will not plug into my computer so I am guessing I need a new one.

Only the blue sky and the green grass
Go on forever in this world
Where seconds feel like eternity
And years pass in blink of an eye
