What you definitely MUST NOT DO when creating youtube videos...

I saw the most terrible video on YT just now. Type in "angry president says google" to see what I mean. The search should show up a cartoon-style President Obama giving a speech. Ouch.

Now, the video content is rather ghastly, but the idea behind the video itself is simple, and could be put to good use.
I think this video was made using a website very similar to sitepal, and video capture software similar to camtasia or some other screen capture software (there are many free ones).
The background image - I know you can use google logo generators online for that kind of thing, and just upload it for your background image.
Anyway, you can make some funny home videos just for fun using this method but you would need to check copyright conditions on the websites and software you use before ever dreaming of using their stuff for your own commercial purposes.

Definitely a must not do .

Ok, I have an actual link now.. watch the Angry President video here...

Be aware there is some bad language in the video. As for me, I like bad language so I give it the thumbs up!!
