title: ffmpeg h264 problem: "File for preset ... not found" on XP
body: <p>i have xp and since i'm not familiar with compiling i downloaded win32-static version of ffmpeg, svn-r26251. i want to resize an mp4 (1280x720 originally) video to get a smaller file size with approximately same quality. My command is:</p>
  
  <p>ffmpeg -i ma.mp4 -vcodec libx264 -vpre hq -s 640x360 ma2.mp4</p>
  
  <p>however it says "file for preset 'hq' not found". i tried -fpre, made no difference. without libx264, the resulting file, ma2.mp4, won't play in jwplayer, you just hear audio. (the reason is that it is not "mpeg4(h264)", it is just "mpeg4"). what should i do?</p>
