Everyone has watched a presenter fight a YouTube seek bar on a projector: the ad plays, the video starts at the wrong spot, a related-videos wall appears at the worst moment. The two-minute example becomes five minutes of fumbling.
Trim the video before the meeting instead. TubeChop gives you a link that starts and stops exactly where you set it, so you click once during the talk and get back to presenting. It works just as well in remote meetings, where you can paste the clip link in the call chat.
