Hi -

        Sorry to report that the improvement in bitrate using the new  4:1:1
        conversion capability of y4mscaler was a ghost - I used the wrong
        script to encode the movie trailer.   That clip was letterboxed
        differently and thus had different top and bottom areas turned to
        black (by 'yuvdenoise -b ...').   Of course turning more of the picture
        to black will save bits.   Sigh.

        ARGH.  

        There is an improvement using the new conversion method but at .5%
        it's not as spectacular.   Still, over a 100 minute movie it makes
        a difference.

        Steven Schultz
