[FFmpeg-user] h264 3 Pass

I was trying to do a 3 pass encode, following the instructions I found 
as follows:
*-pass <1,2,3>* (FFmpeg)
Used with --bitrate. Pass 1 writes the stats file, pass 2 reads it, and 
3 both reads and writes it. If you want to use three pass, this means 
you will have to use --pass 1 for the first pass, --pass 3 for the 
second, and --pass 2 or 3 for the third.

However I got this message from FFMPEG, "The value for pass was 3 which 
is not within 1.00000 - 2.00000"

Any insights on how to do 3 pass with ffmpeg and x264?
