Yes. I'm using one compiled Sept 15th 2011 and it still uses the "old"
command line style. The "c:v" format was introduced October/November
time last year IIRC.
If you want to try the recode with the version you have, use:
-vcodec rawvideo -vf scale=1280:720
I think you can probably drop the rate setting (r:v 30/1.001) at least
for the test.
As you're recoding to raw video, you do realise you will need LOTS of
disk space don't you?
