Screencast-o-matic is a very cool website. Your desktop and or camera becomes a video and your microphone becomes the audio for you to create videos for FREE. It worked very well in creating the videos- it is so easy- and it saved to my computer easily. The only problem i had was then putting the video to youtube. So I tried to manual upload it to youtube and BAM! It worked. Please try it. and check out my youtube video.
