I need to get rid of interlacing.  This is sort of a corner case....  
The camera I use is vehicle mounted, and very wide angle.  It's also 
interlaced, so at speed the two halves of the frame are out of sync as 
the vehicle has moved.

What I want to do is to throw away every other line, then duplicate the 
remaining lines and stretch the image back to the original size.

In other words:

Image is 640x480

throw away every other line; get 640x240

Now duplicate every line and get 640x480 back

Can I do that with ffmpeg?

Help us raise money for my kids' swim team!
