Of course not! What I asked was "how does this performance change if you omit all the filters" - and you are *not* supposed to use "-c:v copy", so we can see approximately how much of your CPU performance is used by the encoding process, and how much by the filter. > so the drawtext re encoding do high cpu usage, I use the notebook ( > thinkpad i5 3 generations) gpu is no to perfect :) That's not true. The filter *implies* not being able to do "-c:v copy", but it may not be the actual filter using all the compute power, but the CPU-based encoding. And if so, we might be able to help you by recommending other encoding parameters or use of a GPU based encoder.
