Still further, the masking uses black and white masking in the vMix software.
Further, the initial state is one of the combination scenarios, the final state is one of the combination scenarios, and the initial state and the final state complete a dynamic effect between the two states through a Merge switching function in the vMix software.
Furthermore, the shape of the cut picture is a closed figure.
Furthermore, the one combined scene has at least two of the cut pictures, and the position of each of the cut pictures is different.
Further, the trigger signal may be transmitted through a GPI protocol or a TCP protocol.
The dynamic windowing method for the vMix, provided by the invention, has the following beneficial effects:
the computer with the vMix software simultaneously receives the multi-channel signals, displays the multi-channel signals through the vMix software, realizes a windowing function, and ensures that the video live broadcast effect after windowing is better in a cutting mode with high degree of freedom, which is also a function difficult to realize by switching a station machine in the industry at present;
the windowing form of the invention has rich freedom, and the customized cutting effect can be realized by manufacturing the windowing schematic diagram, so that the windowing aspect of the competitive electric industry can begin to evolve and iterate;
in view of hardware equipment, the hardware required by the invention is only a computer with a video acquisition card, and compared with the traditional windowing effect and the use of a switching machine, the invention has obvious cost-reducing effect.
