Hello :

My destination is mp4, and it's ovc and oac should  be xvid and aac, or it could not be played in my cellphone.

I have searched about mp4box, and i found it has nothing to do with Linux.
All documentation and software are based on Windows(but i have no Windows).

Yes, quality of the movie is good with 2-pass enc. But it's still avi . And it should be converted to mp4 . I don't know how to do it besides ffmpeg .

My idea is : if i can use xvid to convert to aiv, then i could use command
ffmpeg -y -i $avi -vcodec copy -acodec copy -f mp4 $avi.mp4
to make the destination. With this method, the quality could be maintained i think. 

My video is anime .

First, I don't know about Xvid options. Second, my testing has showed
that lavc mpeg4 yields better quality and speed than Xvid. Why do you
want to use Xvid?

Oh, and I forgot to ask. With your latest two-pass encoding (which you
already told me that it worked), was the quality good?

Oh, and so we can help you more, you should tell us something about
your video. Is it a live action movie, or is it anime? Also, use the
command
midentify YOURMOVIE

And post the output here
