Why are the DVD extended PAL and the BluRay extended editions of the movies different lengths? No its not the credits, its the FPS they play at.

Hi all

ive mentioned this a few times, and been called crazy, and that the different run times are due to fan credits on different versions ect. and not as i claim, due to the FPS of BluRay vs DVD PAL.

and ive always wanted to believe i was wrong. but ive always been away from the ability to check this for my self, and by the time i am home, i have forgotten..

tonight, i have been reminded, and i am able to check!

I am using the 2011 UK BluRay 3 movie set, and the Extended DVDs PAL version from the years they came out, ie 2002/2003/2004. and Playing them on an XBONE PAL.

in the table below is a full breakdown of the times. by disc, total time, no credits, only credits

Time source Fellowship Towers King
DVD1 1:41:19 1:42:11 2:02:22
DVD2 1:57:30 2:03:34 2:10:02
DVD full run time 3:38:49 3:45:45 4:12:24
DVD no credits 3:12:24 3:25:59 3:51:27
DVD credits 26:25 19:46 20:57
BR1 1:45:43 1:46:36 2:07:40
BR2 2:02:34 2:08:51 2:15:35
BR full run time 3:48:17 3:54:27 4:23:15
BR no credits 3:20:43 3:34:27 4:01:26
BR credits 27:34 20:00 21:49
Wiki time full 3:48:00 3:55:00 4:23:00
Wiki time no credits 3:28:00 3:43:00 4:11:00
Wiki time credits 20:00 12:00 12:00

so as you can see. there is a difference in run times of DVD Extended, BluRay Extended and wiki times.. which should not be the case. as they are all for the same movies.. all extended..

Time source DVD BR Wiki
Runtime full 11:36:58 12:05:59 12:06:00
No Credits 10:29:50 10:56:36 11:22:00
credits 1:07:08 1:09:23 0:44:00

so the credit times of DVD vs BluRay are only 2 mins out.. with Wiki being 23-25 mins out

but the actual movie run time, is 27 mins difference between the versions, and Wiki being 26-50 mins out

now one theory ive always given, and have proven below, is that the FPS they play back at is the culprit

movies are filmed at 24FPS. they are shown in Cinemas at 24FPS, but home video has a difference.. BluRay and DVD-NTSC both play at 24FPS, but DVD-PAL plays back at 25FPS..

what does this mean? well 2400 frames will take 100 seconds at 24FPS, but only 96 seconds at 25FPS.. now lets do a calculation from the BluRay of how many frames it should have at 24FPS over 12:05:59,

  • 12 hours x 60 = 720 mins
  • ((720mins + 5mins) x 60) + 59 = 42559 seconds
  • 42559 seconds X 24FPS = 1,045,416 frames. approx

but played back 1FPS faster, would only take

  • 1,045,416 frames / 25FPS = 41,816.64 seconds
  • 41,816 seconds / 60 = 696.944 mins
  • 696 mins / 60 = 11.6 hours

  • 0.6 hour = 36 mins

  • 0.944 min = 56.64 seconds

would equal 11 hours, 36 mins and 57.36 seconds.

which IS the DVD Extended PAL versions run time, to within 0.64 seconds... (calculating frames for the DVD version is 1,045,450 frames, or 34 frames more)

please note, i am unable to get the actual frame counts on the xbox, only to the second it rounds it too. hence the discrepancy of 34 frames or 0.64 seconds depending on calculation route

TL:DR

So anyone who has the PAL DVD Extended version of these movies, get the BluRay. you are NOT watching to full experience. We get almost 30 mins less over the 3 movies. due to FPS differences
