ok, that explains that, thanks


Maybe you can clarify something for me.  I did a lot of testing using
ts as an intermidiate container as I chopped things then concated back
all the ts files to a .mp4.

I was having trouble, then I switched to chopping things up into
.mp4, and concating all the mp4 into a new mp4

things work better, this makes me think I don't understand the diff
containers...  if I want to chop up input videos should I just chop
to mp4 then concat all pieces into mp4 or is there a better intermediate
container type to use?
