Here's a clever little trick to pass on to students and staff who want to show a section of a YouTube video without streaming the entire thing.Just append the to URL #t=XmYs where X is how many minutes into the video and Y is how many seconds. These values are displayed at the bottom right of the YouTube video player's toolbar if you want to get exact timings.
Starts the clip at the 1 minute 5 second mark (actually it starts about 2 seconds earlier in practice). Note in the screen shot that the red line that tracks the progress of the stream doesn't start from the beginning of the video but from your nominated start point.
Saves you the embarrassment of a slow download and irrelevant lead material.
