Hello Christian,

Thank you for some very interesting results.  Could you do a run with:

x264 --bitrate=8000 --ref=1 --keyint=30 --scenecut=-1 --bframes=1
--no-b-adapt --threads ${NTHREADS} -o output.264 input_1920x1080_512.y4m

and with threads up to 256 or 512?  I suspect that will scale much
better.  Thanks ;)

Regards,
--Alex
