Here is my command.

ffmpeg -i CCC2009Sampler.wmv -acodec aac -vcodec libx264 -fpre "libx264-lossless_ultrafast.ffpreset" -crf 18 -strict experimental -y CCC2009Sampler.mp4 Consider using a slower preset (ultrafast is really ineffecient compared to the slower presets; even simply turning CABAC on will drastically increase quality at the same bitrate) and/or using a higher CRF value (to decrease bitrate and quality).
