Hello everyone. I’m Hui! Welcome to CAMystery. First, stabilize your phone with a tripod. In your camera app, lock your exposure and other settings. Prepare a sheet of brightly colored paper that does not match you or your clothes. Shoot two videos, one with the paper, and one without. Create a new project and load the clip without the colored paper in KineMaster. Slide the timeline to where you’d like to start. Tap Layer, then media, and load the clip with the paper. Add the video layer, then tap Split Screen, then Full Screen. Tap Chroma Key from the Options Panel. If needed tap Key Color to choose a color that matches the paper. Adjust the settings to make the paper transparent. That’s it!
