After thinking a bit about it, I just added a new signal to renderer.cpp, 
called:

void frameUpdated(int)

That signal is emitted every time the frame is updated without a seek event. 
Currently, the frame is updated not only when an effect is added, but also 
every time the monitor needs a refresh (for example when another window moves 
above it), so you will get a few extra calls, but that's also an occasion to 
track unneeded refreshes :)
