1080p/24P question

[moviefanaticfan]

I am confused about what 24P is? is it a great thing when watching movies on a 300 Model or is it a drawback?

Progressive refers to a whole frame being shown in one field. 24 refers to the number of fields shown per second. Hence 24P means 24 frames are shown per second.

Films are shot in 24p. There's a long story on why this is preferred in viewing rather than 30p or 60i.

24P usually refers to 24 progressive frames per second. This is the number of frames of film displayed every second on movies shot on film (ie: most movies today).

NTSC TV systems (by north american standard) by default are 60I (interlaced), (Actually 59.94Hz, but that complicates it).

In interlaced signals (eg : 480i or 1080i) , the progressive frames are sent alternately in even lines and odd lines. (Ignore the art of going from 24P to 60i, this involves 3:2 telecine where fields have to be repeated in a 3:2 pattern.

If your TV can handle 24P native, that's the best option for playback of bd movies (if your player can support this output).

Most of the time, 1080i60 is the normal feed from a player to your TV. In that case, what you get depends on the particular TV. If you have a entry level to mid-priced TV bought say, last year, it's a virtual certainty that the TV takes each 540 lines from each field and upscales it to either 1080 or 768 or 720 (depending on the TV native resolution).

Honestly I gotta say I noticed more weird artifacts with 1080/24 on, than off. I am using the sony kds60a3000 with the panny bd30. I notice no benefits.

Perhaps your settings aren't just right.

I noticed a much smoother and less judder picture when I switched from a 60HZ 1080P LCD with 3:2 pull down on Blu-rays versus my new Sony XBR4 120HZ 1080p LCD with true 24p turned on with the panny 30D.

I definately notice the difference between my 40" LCD at 60hz VS my projector at 24p. Much smoother motion and feels much more like viewing a film vs a tv show.

yeah, it feels more theater like. The Judder I got on my 60Hz Samsung LCD really annoyed me sometimes in certain movies. Some people it does not bother, but it does me.

Do you ever notice any artifacts, I believe it does give you less jutter but I also noticed other things hard to describe but unatural. What I saw was a tracing like affect not ghosting but were the edges of the scene or people. I did ever kind of test on this and when I turned the 24 off it went away. I haven't turned the motion enhacer back on either but I might try that. I honestly think alot off these new features cause more artifacts and hurt more than help.

But whatever it must just be a preference.
