Video encoding

x264 HD benchmark
This benchmark tests one of the most popular H.264 video encoders, the open-source x264. The results come in two parts, for the two passes the encoder makes through the video file. I've chosen to report them separately, since that's typically how the results are reported in the public database of results for this benchmark.

Another ray of light for Bulldozer here, in the more multithreaded second pass of the x264 encoding process. The FX-8150 matches the pricier Core i7-2600K—and clearly outruns the i5-2500K. Too bad about that first pass, which is also part of the overall picture.

Windows Live Movie Maker 14 video encoding
For this test, we used Windows Live Movie Maker to transcode a 30-minute TV show, recorded in 720p .wtv format on my Windows 7 Media Center system, into a 320x240 WMV-format video format appropriate for mobile devices.

Live Movie Maker combines both passes into a single encoding time metric, and it places the FX-8150 just a few seconds ahead of the Phenom II X4 980.
