Hahaha i had the same problem when i tried to learn how to embed videos. ohkae so well 당신 go to the "embed a video" button, 당신 will see it if 당신 answer 또는 ask a question. so it will say copy the url. so 당신 go back to your video, click the share button below the video nd then copy the url. it will jusst look like a whole bunch of letters nd numbers. then 당신 go back to your 질문 nd paste it. thats pretty much it
