Videos, Pictures and Background Music Needed:

How to Do the Flash Warning on TikTok: 4 Steps Guide
This is an easy tutorial to create TikTok trending Flash Warning video. We break it down into 4 Steps, each can be accomplished by an App.

5. Now you have this outline tool, which acts like an area selection tool. You need to draw on the screen to make sure the person in the picture get covered by the red color.
Note: PicsArt are AI-powered, and can discriminate the person from the background. Therefore, you can roughly sketch the area, not worrying the line goes out of your idol's silhouette.
6. Manually adjust the edges and outlines to fine tune your selection. There are two tools to use in the stage:
- Restore Tool: it will add the area to be covered. For instance, the AI-powered selection tool might not cover the eye-lashes of the person. You can use the restore tool to add another brush, so that the eye-lashes and hair and other area get covered. Drag the knob to adjust the size of the brush.
- Erase Tool: erase the area you don't want to keep. You can pinch to zoom-in on the image, so that you can see outlines clearly and precisely. If any section covered by the red color belongs to the background, go use this erasing tool to remove the red.

4. Tap the plus + icon to add the transparent PNG picture of your idol.

5 (optional). If both of you are facing the same direction, you can tap on the clip of your idol, and find the Mirror tool at the bottom. Tap on it, and this will flip his or her face to the opposite direction.
The aim is to make sure you two are "looking" at each other, intimately.
6. Adjust the position and size of both clips if needed.

Step 4. Use CapCut to combine videos together.
Finally, let's crack on the most exciting part: merge videos together. The end product will be a combination of two scenes. In the beginning, you are filming a selfies video, looking at the camera, and the color is normal; Suddenly, a hand touches you and turn your face to the other person, and the color starts to flash with thermograph style filters.
1. Launch CapCut app from the home screen, and tap to add new projects.
2. Browse your camera roll, and select video clips made in the previous steps:
