It works, but it is a very brutal stop, i can do the same in compositing with a freez picture.
In fact, what i want to do is a smooth freezing, the flag slow down and stop smoothly.
I didn't find a way to slow down with the curent time, it just stop even i try to key a larger value in the time.
Maybe i don't know an other way to use it.
In fact it is really a parameter who do the same thing than the conserve i need.
Thanks for your tip it is good to know to
