Okay.  I will try this  (actually, I tried it and it didn't work, but I probably didn't do it right).

Also, I was able to figure out my main question with the scale functions.

I have another question.  If my input frames are YUV422P compressed with ffvhuff
and my output frames are also YUV422P compressed with ffvhuff, can I somehow
copy them directly from input file to output file without decoding them?  Maybe
copy the packet directly?  I'm currently using AVI containers.  Is this dependent on 
what container I choose?  If so, is there some container that allows this?
