I found a nice, simple tool that creates a URL for just the part of a YouTube video that you wish to share. Say for example a YouTube video is five minutes long, but you are only interested in sharing a particular 30 second segment of it to make a point for a class. This tool, https://splicd.com , let’s you do exactly that. Best of all it is extremely easy to use and does not require signing up for an account.
Once you are at the site, the steps are almost self explanatory. You paste in the URL of the YouTube video, enter in the start and end times for the video segment you want to share, press continue, and Splicd.com creates a URL with that segment. You then send the Splicd.com generated URL to your class for viewing.
