Combining and extracting videos

In this task, we required to download so you think you can dance video to be combined as the video is given in parts. I was using movie maker software as this software is easy to be use for combining videos. After combining the video, we need to extract the video contestant by contestant. This experience is really amazing as i was never thought that we can extract the video. for example, contestant black, we just take video about black only and take it out from the video. This can be applied when we want to make a teaching aids from a video, but some features on the video is no suitable for the children. we just cut the video and take the part that we need only.
