Notch is able to render content to a virtual webcam known as NotchCam. This enables you to render in realtime directly into tools such as Zoom, Google Hangouts/Meet, OBS or any software that takes a web camera input (via DirectShow).
This solution enables a whole range of applications from grading webcam inputs, to virtual studios, enhanced backgrounds, green screen powered environments, bottom third graphics or just stunning presentations.
How to use NotchCam
During installation, Notch Builder will install & register ‘NotchCam’. This is a DirectShow virtual camera device that Notch Builder will pipe it’s output into. You can use this NotchCam device in any application that supports DirectShow.
If you attempt to use the NotchCam in your 3rd party app prior to outputting from Notch Builder you’ll see a pre-transmission test image.

Using NotchCam in exported standalones
You can use the virtual webcam when running Notch standalone executables. To do this, you need to start the standalone from the commandline using parameters outlined below:
standalone.exe +livestream DirectShow +width 1280 +height 720
You can choose the resolution of your choice, but it must be set as part of the command line parameters. See the Standalone section for more parameters.
