Hi there, Paul. How would I be able to check which filter uses the most processing power?
I am encoding in hardware with my video card, so it's only the decoding and filters that are eating up CPU. What I am seeing is that only one CPU shows any load. I have a suspicion that it is the remap filter that eats the most CPU, but I am running two remaps in parrallel, so I would expect to see at least two CPU showing load.
