4. Director Switching

After configuring the template, the background staff can select the corresponding template to switch the output screen in real time, which is used to quickly switch the screen of the director console during director switching.

After configuring the template, you first need to select the corresponding input origin for each module. The display screen of each module will display the selected input origin screen. Click Save to temporarily store the video input information. Click Preview to save and switch the current video preview area screen to the new template-configured input combination screen.

In the video preview area, you can check the content of the video screen to be output in advance, and confirm that the output screen meets your expectation. Click Output to confirm the output of the screen in the preview area.

If you need to control the sound of the input origin, you can drag and control the sound control bar on the left side of each input origin screen in the video input area. The default sound size is 50. You can decide the final sound combination effect by controlling the volume of each input origin. After the adjustment is completed, you must click the save or preview button in the template to take effect.

In the video preview area and video output area, you can also drag the sound control bar on the left to adjust the volume of the output sound.

6. Video Matting

Video matting allows background operators to cut out the video to achieve a movie green screen effect. Move the mouse to the video area, click the image button to enter the matting setting interface.

In the matting interface, you can set the matting parameters accordingly, and the detailed functions of the corresponding parameters are as follows:

• Image Matting Setting: select to enable/disable matting
• Background Color: To select the standard background color during the matting process, click the color box on the right to pop up the color selection interface to select the matting background color, and the color in the video that is the same as the selected color will be cut out.
• Similarity: Drag the similarity setting bar to adjust the similarity percentage. The larger the similarity value, the closer the matting color is to the defined background color. A similarity of 100% means that the background color needs to be completely matched, and a similarity of 1% means that any color is matched
• Degree Of Integration: Drag the degree of integration setting bar to adjust the integration percentage. The meaning of this integration value is the transparency of the remaining video content of the matting when it is superimposed on the main screen. 100% is fully transparent, which means no other video sources are superimposed, and 0% is completely opaque.

After clicking OK, the matting settings will take effect. If you need to combine screens with other video screen, you need to add multiple video origin in the custom template, including the matting screen, and set the matting video origin level upper than other video screens. Thus, the replacement of the green screen in the video background can be realized.

• Watermark Name
• Position
• Size
• Transparency：0% is fully opaque, 100% is fully transparent.
• Adaptive: Set whether the watermark scales proportionally with the resolution of the output video. If you select Yes, the size of the watermark will be consistent with the output video resolution.

After setting the watermark, you can click the watermark button to be displayed to determine the watermark to be added, and the effective watermark will be displayed with a green dot in the upper right corner. If you need to cancel adding the watermark, you can cancel by clicking the corresponding watermark again.

8. Time Delay/Disable
