Intra-frame compression doesn't:  it's less efficient, but has more consistent performance, especially for high noise and high motion video.  Setting the GOP length to 1 frame means using intra-frame compression.     * Most video compression is inter-frame: it exploits similarities between frames so as to achieve better compression efficiency.
