There are a few things you should know before you start filming someone on TikTok. First, make sure that the person you are filming is okay with it. If they’re not, be sure to ask them first. Second, make sure that your phone is charged and that you have enough data to keep up with the video. Third, be aware of your surroundings and be careful not to cause any trouble. Finally, remember that there is always potential for embarrassment or even violence if you film someone without their permission.
