Capture your desktop into a video free of cost.

Today there is a number of websites, like youture.com, which provide us a space to upload videos. Many of these websites offer "Earn By Uploading" functionality. Youtube.com has also started a partner program, in which you create an account with them and they would give you a webpage that would show your profile and the videos that you upload. When ever someone watches your video, some kind of google ads or banners are shown along with your video, you earn money. Even if you don't have a camera to capture videos, you can still create movie files. You can capture the activities of your desktop into a video file and then you can publish the video on Youtube.com. But be careful that your video must have such a content that teaches or entertains others. Because you have to create an account with Google Adsense program also to earn money from Youtube.com. Google would first check your videos quality and then google would approve you if your videos have a good quality, else your Google Adsense account will not be approved by google, and your videos must be captured by you.

Do not worry, there is an Open Source software that helps you create videos free of cost, which is CamStudio. You can download this software freely and you can use it anyway you want.
