FFmpeg -ss weird behaviour?

This is an educated guess. When ss occurs before I it is treated as instructions for the input, so the first frame of the video stream is the one at 30 seconds. When ss occurs after I it is treated as an effect, and the first 30 seconds of frames are read and dropped, leading to a performance difference.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
