YouTube makes it easy for you to pinpoint specific times or moments in a video. Let’s see how you can take advantage of this. 1. While sharing a video: When you click on the Share link below a YouTube video, look for the Start at: option under the Share tab. Check the box next to that option and specify a start time for the video in the hh:mm:ss format or the mm:ss format. The current time in the video appears in the Start at: field by default.
