What's the deal with 24p?
Posted Oct 1st 2007 2:13PM by Ben Drawbaugh
It's one buzz word after another in the world of HD and the latest is 24p, but what's the big deal? How can less frames per second be better? Like most things that don't make sense, the reason isn't a good one. Without going into much detail, the reason is because movies have been shot at 24 fps for years and to watch a movie at any other frame rate means there's some funny business going on. The problem is that most TVs can't display video at this rate, so even if your player can, you're probably still watching it at 60hz. Then to top it off, if you don't see any judder now, then why worry about it in the first place? Either way, if you want to try to understand the entire mess, follow the read link over to HighDefDigest and read there comprehensive write-up on What's the Big Deal About 1080p24?
Edit: I looked into it a bit more and it seems there's a confusion with 24P vs 24Hz. 24Hz is where the films are shot at and best viewed at that rate.
