This is what I use - An inswan document camera is $99. itube studio is $20. Connect the inswan to your laptop. Now you can use regular paper pencil to write, draw graphs, show text, pictures etc. Use PhotoBooth to make a video, which is an mov. Then use itube studio to convert it to "Youtube" mp4, which has the right codec etc, & then upload to youtube.
