I have this file,it is 1:85:1 16:9 widescreen,the Xvid video itself is 704x384,I want to encode it to anamorphic widescreen using CCE & Avisynth,now using Citizens aspect ratio calculator i put in the 704x384,and for source I used NTSC Anamorphic 16:9,and what it gave me was this:

NTSC Anamorphic (16:9) = 720,393
Lanczos4Resize(720,393).Addborders(0,43,0,44)
does this seem right?is this 1:85:1?
or should I use:

source PC normal (1:1)
NTSC Anamorphic (16:9) = 720,477
Lanczos4Resize(720,477).Addborders(0,1,0,2)

thanks for any and all help
