I know, it's been a while since the last version ScreenStudio. Don't worry, I just released a new version (1.4.0).
A single new feature: Record/Stream only your webcam
You can now record only your webcam by selecting the Screen source "None" and a Webcam from the available list.
The overlay will be applied over your webcam instead of your desktop.
An easy and quick way to record your vlogs.
