surely, but if the target-user is running Windows, does want
WMV and ffmpeg only supports wmv2 and not wmv3 you have not
that much options

indeed - i missed the 1080x1920 and VLC scaled the output
but you do not need some megabits with x264

i was asked to convert a video from a colleague for a customer
because his Apple refuses to encode WMV at all and used my
CLI application asking some questions before using a PHP
wrapper and acted like doing H264 stuff for iPhone in
answering the questions :-(
