One great reason for 24 to 29.97p is cross-platform delivery. So many delivery requirements these days are demanding progressive delivery so that there's no interlacing for streaming or web placement. It makes sense. What also does not make sense is that many of these requirements prohibit frame rates above 30, so a real 24 to 60 progressive pulldown is impossible. So you're stuck with 1:1:1:2 pulldown, which, yes, blows.

Hi Tod,Excuse my ignorance, but why would you need to convert 24p to 29.97p?If it was for broadcast, I would either conform to 23.98 and then add 3:2 pulldown, or standards-convert with a decent quality converter (e.g. Alchemist/Teranex) and go 59.94i that way. Either of those options look FAR better than the stuttering motion you get from "4:1 progressive pulldown" in my opinion. And if you don't like to use a standards converter because you're trying to keep the progressive look of 24p, then just avoid any kind of "Motion Compensated" or "Optical Flow" methods.Or is there some other reason for going to 29.97p?Cheers,David
