You have not provided enough information to get an answer to your question. What are you using to record the video? Are you using a phone, camera or camcorder? Who is the manufacturer (Sony, Canon, Samsung, Fuji or someone else) and what is the model number of the device you are using? Some devices have a pause button usually symbolized by "||" (without the quotation marks) while others do not have a pause button and you have to stop recording and then resume recording.
