How to add filesink to a videomixer

I'm setting up a pipeline with gst-launch to chromakey one video over
another.  I've got it working with output to the screen.  However, I want to
send the composite to a new movie.  But, I can't correctly fit a filesink
into the pipeline.  Here's what I've got that works.  Can anyone tell me how
to add the output?

gst-launch-0.10 \ 
-e filesrc location="over.mov" \ 
! decodebin \ 
! queue \ 
! ffmpegcolorspace \ 
! alpha method=custom target-r=0 target-g=0 target-b=255 \ 
! videobox border-alpha=0 right=1 \
! videomixer name=mix \ 
! ffmpegcolorspace \ 
! autovideosink filesrc location="under.mov" \
! decodebin \ 
! queue \ 
! ffmpegcolorspace \ 
! videobox border-alpha=0 left=1 \ 
! mix.
