Working principle: The first signal collects high-definition images on the large screen, and the second signal collects semi transparent large screens and portrait images covered by a virtual green screen (green film) through a shooting device. Then, using green screen cutout synthesis technology, the second signal is green screen cutout, retaining only the portrait. The two signals are then synthesized to obtain high-definition images of both the screen content and the portrait, solving the problems of blurry and reflective images in direct shooting.

A virtual green screen (green film) that can adjust color value and transparency, allowing you to achieve good cutout effects in different lighting environments.

After CourseMaker 7.0 synthesizes the recorded courseware and the remaining portraits after the green screen cutout, we can get high-definition pictures of the courseware and portraits, and generate a virtual camera, CourseMaker Virtual Camera, which can be called by live broadcast platforms such as video number, Tiktok, and Xiaohongshu. If you are used to live broadcast tools such as OBS, you can also use it in OBS software.
