You really can't make VP8 look good but if you insist on trying, try this batch file for ffmpeg:
>ffmpeg -y -i %1 -c:v libvpx -crf 18 -b:v 2M -pass 1 -an -f webm NUL && ^>ffmpeg -y -i %1 -c:v libvpx -crf 18 -b:v 2M -pass 2 -an "%~n1.webm">del ffmpeg2pass-0.logI used that for this one. Typically you wouldn't use such a high bitrate and low CRF (lower is better) but you can get away with it in this case because it's only 3 seconds long.
