Weird. Are you sure? I tried encoding using both "-coder ac" and "-coder 
vlc" and it resulted in a different file size and different performance 
(and as expected AC resulted in a smaller file size and encoding was 
noticeably slower).

The difference in filesizes when using the lossless ffv1 codec:
Coder    Filesize
VLC      19923786
AC       19290550
