Any chance you can get a better quality video. I work on these ALL the time and it doesn't sound like a rod knock to me-rod knock is a much deeper sound. It sounds to me like your 4 18mm bolts holding your clutch assembly to the flex plate are loose. Remove the dust shield and check those bolts. If they are loose, pull each one out at a time and put thread lock on them, and tighten them in.
Good luck
