I don't know what you mean.  Is this more correct?
    libx264 is the best AVC encoder available
Or is this correct?
    libx264 is the best encoder available
or this?
    There are better AVC encoders available
or what do you mean?

"Among the >100 codecs implemented within FFmpeg, 
MPEG-4 ASP is one of them,

Okay, I understand.

I use mencoder to 2-pass-encode AVI files with vcodec=mpeg4
at a bitrate of 10,000,000 bits per second.  I have tried to
get ffmpeg to do the same, but either failed, or it was slower.
Feel free to offer an example way of doing this with ffmpeg.

Also, I plan on using mencoder and libx264 to produce MPEG-4
AVC files and 422-format pixels.  Can ffmpeg do this?

I'm not 100 percent sure what this statement means.

I still have problems with 'blue' pixels when converting from
ffhuff-compressed AVI files with yuv422 pixels to non-compressed
AVI files with yuv422 pixels.  I never saw a response to that issue.

Thank you for the time you put into responding with me.
