Framerate conversion

Input duration

  • 12 frames
  • = 0.501 second(s)
  • Framerate stays 23.976 - so nothing to do for conversion


  • Calculate # frames from time duration and vice versa. e.g. 93 sec @ 24fps = 2232 frames
  • Calculate how audio and video should be manipulated to change from one framerate to another, using soxand/orffmpeg
  • When is this necessary? If you have a video that was recorded in 25fps(PAL) or 30fps(NTSC), and you want to show it on a cinema screen: you have to convert the framerate to 24 fps.
