If your on a mac these steps will be a bit simpler (and compatible :P):
Use your iSight (the little camera in all mac machines made after 06) and Photobooth.app (in your Applications folder) Then, in Photobooth press the big red camera icon to take pictures, take as many as you need for your movie,
drag all the photos from the bottom of the Photobooth window into a folder somewhere;
next open up Quicktime Player.app (also in apps folder) and navigate to File > Open Image Sequence you should get a prompt asking where your images are, navigate to the folder with all the images in it, press okay, choose a framerate
Your movie will now be compiled, test it out and change the fps if necessary and then goto File > Save As... choose somewhere to export too (the default export settings should do fine)
and then your done!
Optionally you can next import to the flash authoring tool and upload to NG.
hope that helps someone :P
