Movie Editing

whats the easiest and best free way to edit videos and overlay graphics etc on to a youtube clip?

I have footage I have filmed and want to put credits etc onto it, as well as jumping between camera angles (ie different clips)

Has anyone done this?

Anybody able to help with this please?

Not really sure if it does what you're looking for but Sony Vegas software may work, get the free trial and you can see if it does the job you want it to. http://www.sonycreativesoftware.com/vegassoftware

Or maybe give Adobe Premiere a try, can get a trial for that too. http://www.adobe.com/uk/products/premiere.html

Thanks for that but I need something thats always going to be free!

Its only simple editing I am after.

Well then the only other one I know of is windows movie maker...

yeah windows movie maker is the only free one i know. Unless you download a ripped copy of Sony Vegas or Adober Premiere
