What is the best video camera to use to shoot you tube style jewelry tutorial videos?
I'd recommend anything that is NOT a camera phone, that has good sound.
So if you have a digital camera that can record video and has decent sound you should be ok.
Also lighting is important.
If you want to make some serious videos go with an HDV or miniDV camcorder.
The Flip and RCA Small Wonder are decent and affordable and cost about $150 and are compact and made for youtube.
Perhaps you can test some out at a local store.
