The artifacts in video A are primarily caused by scaling, they're not
artifacts of VP8. Swapping in h264 and keeping all the other pieces the
same would look similar. This is going to affect everything from perceived
quality to achieved bitrate. I'm not sure you can draw any conclusion from
this test, and I don't think it lives up to its goal of "showing good VP8
implementation in best of conditions."
