1080p VOD clarification

24fps(Hz)

This thread should have ended as soon as that answer was posted. That answers the question, period. Ok, maybe a nitpicker could have written 23.976fps.

Progressive video at rate of 24 fps (actually 23.98 fps) for 60 Hz. This is a standard & it is what E* uses.

23.976 is for NTSC. ATSC is 24fps.

And the nitpicker would be wrong.

1080p23.976 is part of the ATSC standard.



When film is telecined for NTSC it is slowed by 1/10th of 1% down to 23.976fps, so that after 3:2 pulldown you get 59.94 fields/sec. And more Blu-ray disks are 23.976fps than 24fps. In the absence of any other information, I'd expect Dish to be sending 23.976fps, not 24fps, just because 23.976fps seems to be more prevalent in production and distribution. Plus, I have several TB of film-sourced 1080i captures from Dish Network, and guess what, they're all 29.97fps, not 30fps. Guess what you get when apply inverse telecine to that? 23.976fps.

So, what makes you so sure Dish's 1080p is 24fps and not 23.976fps? You were already wrong about 23.976fps not being part of ATSC.

Movies don't need to be telecined for NTSC when they are destined for HD unless they were shot at non-film rates.

The NTSC rates are included in the standard because the ATSC demands that the TVs be able to handle analog video (service type 0x01).
