24 Frames Per Second questions

[Blu-Benny]

I was monkeying around w/the menu of my Samsung BD1400 and started looking into the 24 frames per second option.

Currently, I have it turned off, what are the benefits of it being on??? Is it a noticeable improvement with it on?? Does the tv have to have anything special for this to be a benefit??

Thanks for any info anyone has, I couldn't find any threads on this.

If it matters, I have a Samsung LN32A330. It's a pretty basic tv I know, but it's just in our living room w/only the blu-ray player hooked up to it right now.

So, 24 frames per second, or 24 fps, is a feature that lets you output the blu-ray disc at 24 fps, which is how 35mm and 70mm cameras record, by taking 24 frame-shots in a second.

Traditionally, movies were re-encoded for home viewing using 3:2 pulldown, where Frame one appears three times, Frame two appears two times, Frames three appears three times, Frame four appears two times, and so on. This made 24 fps material display at 60fps, which is the standard frame rate in North America (I cannot speak to 50 fps standard re-encoding). To some, this creates a judder effect due to the uneven length of supposedly even frames.

So, blu-ray players let you preserve the 24 frames per second. However, in order to take full advantage of this, the player would have to be connected to a display which properly displays 24fps material by showing each frame an even number of times, something like 2:2 (48 hz), 3:3 (72 hz), 4:4 (96 hz), or 5:5 (120 hz), without interpolating frames, which is a fancy way of saying "adding" frames.

Many television sets will take a 24 fps source and apply their own 3:2 pulldown, thus negating the advantage of 24 fps output. Thus, there is a stickied thread in the display section of the forums which outlines displays that correctly display 24 fps when fed a 24 fps source.

Sorry that was long winded. I got...technical.
