You can also use this tool as your video source on YouTube to record videos on your desktop. Record a video of your desktop and save it to your computer, or decide to screencast your desktop live while using the app. Choose to cut or slowly transition between different sources.Ī screencast is a recorded video of the actions you take on your computer screen. Use the pull-down menu in the source window to add another camera, a still image, a photo snapshot, a pre-recorded video, or your desktop as your video source. The program allows you to quickly switch between up to 12 videos, audio, and image sources.
