I don't understand, when in ffmpeg i do ffmpeg -i <input> i have :

Video: hevc (Main) (hev1 / 0x31766568), yuv420p(tv), 1920x1080, 4997 kb/s, 30 fps, 30 tbr, 998795.00 tbn, 30 tbc (default)

it's show bitrate: 4997 kb/s BUT the size of the file is 114915563 bytes for a duration of 179 secondes. when i do math i have 114915563 / 179 = 641986 bytes/s = 642 kb/s :(

What did i miss ? how to retrieve the average bitrate of a movie and the peak bitrate of a movie ?

  • It's 642 k **B** /s. Multiply by 8 for total kb/s. And it's for the total file i.e. + audio + overhead. – Gyan Feb 14 '18 at 16:00
  • aaah ok ! tss better to write kbps than kb/s it's confusing :( and you know how to retrieve the peak bitrate ? – zeus Feb 14 '18 at 16:12
