What Tools You Need
For those on a budget use Screencast-O-Matic.
If you can afford a bit more advanced then use Camtasia.
For those on a budget, use the Blue Snowball microphone.
If you can afford a bit more, then I suggest the HyperX microphone.
This plug and play webcam from Logitech is BY FAR the best value for money.
NOTE - if you are brand new then DO NOT buy this. Stay off camera.
You should download and install the TubeBuddy tool. It is FREE.
In the next few videos I will show you how to use it.
