Hi, Paul.
First, thanks for the advice.
Erm..thing is that I totally don't understand what you are saying as dumb.
You mean, the expression should be...
[1:v]geq=r='r(X,Y)':a='if(between(t\,0\,9),alpha(X,Y),0)'[alpha]; ?? which
is not working.
Could you show me the exact syntax for me?

Hey,
My cuts are perfect, true IDR. The join is perfect, yet MPV stalls for about 1/2 second and shows
one, maybe two black frames. The only thing I can think of that would screw up the playing across my
joins is MPEG's 'closed_gop' flag. It needs to set it to '1' for the GOP on the early side
With something a complicated as this stuff, I knew I would screw up something. Correction: I fixed
the 'Commands used'.
