I am a blogger and I want to make youtube tutorials for My blog. I know there are many softwares but which is the best free software using which I can use. I know a CamStudio-Recorder is a screen capturing software. I can even take a screen video but I dont know how to hide some personal information is between the video. It means I want to erase and edit my videos. So please provide me some good cracked or free software to solve my problem.
