Sometimes a full Video Editing program is not needed to do a simple splice of a video. A small tool is available for cutting part of a video and saving it as a new file. the program is called 'LossLessCut'. It is a free program for Windows, Mac and Linux. It does nothing else than that, but is useful for removing that unwanted false start to a home movie or not ending when it should. Mark the start point and then the end point of the wanted section. Click on the Scissors Icon and the wanted part will be saved while the original video is left unaltered.
