TubeChop. Many educators are leery of using YouTube, even if they have previewed the video, because there are sometimes ads or other content they did not expect to appear in the video. TubeChop takes a video and allows users to "create" a new video that contains a much smaller segment of the original file. The TubeChop's slider selector is used to create a new start and end point for the video. Then the "chopped" video may be shared either with an embed code for a website or with a unique URL the site has created.
