Hi all,

I'm sure I could figure this out eventually, but I was wondering if anyone 
knew offhand the easiest way to add 5 seconds of black silence to the end 
of a video? I have a number of inputs and am running them all through a 
filtergraph chain like this and just want to add black silence to the end.

-filter_complex "[0:0]curves=master='0/0 0.04/0 .15/.15 1/1'[out1];
