# 二、Layout of the live broadcast environment
## 1、How to arrange the lighting to make the live broadcast picture more textured
- Sitting broadcast: 1 annular beauty lamp in front of you, 1 soft light fill light at 45° on the left and right sides, and 30° angle from the head to the bottom of the fill light.
- Station broadcast: 1 soft light fill light at 45° in front and left and right sides, 30° light from the head down in front of the front light, one side of the two sides is illuminated horizontally, and the other side of the head is illuminated obliquely upwards at 10°.

## 2、How to arrange the green cloth on the background
- Keep your subject at least 6 feet (about 1.8 meters) away from the green screen to minimize scattering and shadows on the green screen background. The result is a softer effect, which is conducive to post-processing.
- Light the foreground and background cloth separately. It's also important to light the green screen evenly. Correct exposure helps to avoid scattering of green light.

# 三、Layer screen settings
After setting up the live broadcast environment, we turn on the E-Thought live broadcaster, add the video source to the live broadcast interface through the broadcast station, and then edit the video source layer. Editing is divided into 4 functional areas:
1. Camera Properties: This ribbon allows you to adjust the size and position of the layer, and you can set local cropping to achieve a multi-camera effect, and set a cutout reserve area so that the green in the area is not keyed
2. Cutout settings: including green screen cutout, AI cutout, mosaic and Gaussian blur
3. Beautifying: You can freely adjust the whitening and beautifying effects
4. Filters: It has a variety of filter modes to beautify the live broadcast scene
