cutvideo(in_vobj, start_frame, end_frame, outfile)

This function extracts a video clip out of a full video using the start and end frame numbers

cutvideo() generates a short video clip out of a full video file based on the user specified starting frame and ending frame. It takes three required arguments: 1) a VideoReader object/handle to the full video, 2) the starting frame number, and 3) the ending frame number. Users can supply a fourth optional argument, which is the desired path of the generated video clip; otherwise, they will be prompt with file dialog to specify when the clip is ready to be written.
