    Sets image-display-duration to length and plays the clip. Images would be
    affected by the length value while other clips will not.
    After the last line was processed, start again with the first line.
    Note: For simplicity, there should be no empty lines, exactly one space
    between length and clip-path, and no extra spaces before or after
    (but spaces as part of clip-path are premitted).
