2drumstix Jun 11, 2010 6:49 AM (in response to 2drumstix)Anyone know what is happening in the encode process when 60fps is encoded to 30, 29.97 ir 24?

able123 Jun 11, 2010 7:21 AM (in response to 2drumstix)Hi,
I did a google search using something like, 60fps sports video broadcast 30 fps
And got a bunch of results you might find interesting....
Here's a section of one forum conversation .....You could narrow your search to find out more as needed....

Interesting, hadn't heard that. You're saying it was shot as interlaced 1080/60i, like a taped football match, deinterlaced to 30 fps, but then then interlaced again (using pulldown?) for 1080/60i (30i) delivery?
Yes. At least the first five seasons were shot with regular interlaced SD video cameras (not HD). I don't know what you mean by "60i (30i)". They can't be both.

My 1080/60i CRT RPTV, presumably, would treat it much like 24p material with 3:2 pulldown.No. It's 2:2 pulldown.
Quote:
But what are all the deinterlacing video processors for fixed-pixel displays doing with 30 fps material delivered at 1080/60i (30i)?Deinterlacing it as if it were interlaced. 30 fps progressive is so rare, I seriously doubt anything would recognize the 2:2 pattern.
Quote:
Understand that some ads are captured at 1080/30p, too. But again the outgoing station signals still have to be 1080/60i, so interlacing of the captured 30 fps would have to be involved, just like duplicate TV fields are involved with 24 fps delivery (2-3 pulldown) to achieve the 60-Hz broadcast rate. -- JohnYeah, but it's a simple 2:2 pulldown like what they do for filmed material to broadcast it in PAL. It's treated no differently from interlaced material. I don't even think the frames are flagged progressive on the DVDs.
