Google has implemented their jumping feature into YouTube videos and it’s really nice. As you know, with most flash videos, you can’t scroll ahead until the video completely loads out beyond the point you want. With a YouTube video, now you can jump ahead and the video will start to load out from the new point foward, wasting no more time or energy loading any of the prior sections of the video.
Above, you can see I clicked the scoller to the middle of the video. It then began to play from the new point and started to load out ahead (and then behind next).
This is a very elegant feature that saves bandwidth and gives the audience way more flexibility for consuming information quickly.
