i have been having a issue for a long time where my x264 setup shows:
mp4 [info]: initial delay 2002 (scale 30000)
i was playing around with some settings and as soon as i remove --b-pyramid from my cmd line i get this:
mp4 [info]: initial delay 1001 (scale 30000)
now is this a bug or is it normal and nothing to worry about? i dont know what that part is trying to tell me other than if my input is 29.97fps which it is then 2002 is wrong and 1001 is correct.
With --b-pyramid
