blu ray player 24p setting image
aftermathr
So...im in the market for a blu-ray player...probably a PS3 after the reviews i've read on it...and its versatility as an all in one unit. What can i expect resolution wise on my 720p Panasonic Viera Plasma when vierwing blu-ray? They are always demo-ing blu-ray on 1080p in the stores...so i cannot get a grasp on what i'm going to see on 720p. Am i looking at a big jump up from DVD? I know the frame rates are higher on Blu-ray...but i know true dvd is in 720p. I have my current setup broadcasting 720p over HDMI on a Harman Kardon DVD player and it looks pretty sharp. My TV's model number is TH-42PX80U. Thanks!

Ordered responses to your query:
-The PS3 is, in fact, one of the most affordable and yet still most versatile units. Highly recommended even if it will ONLY be used for blu-ray playback.
-Resolution depends on your personal preference. Your model supports both 720p and 1080i input resolution - though the native resolution more closely matches 720 pixel for pixel. There should not be a difference.
-I've seen demos of blu-ray on 720 native res LCD televisions for which the quality blows the full 1080 sets out of the water. The picture quality is dependent on more than just the number of pixels. Also, at more than a few feet away your eyes cannot see something that small, anyway - so the difference in sharpness will not be that noticeable.
-On this television (it is a 2008 model), the dynamic contrast is listed as 1,000,000:1 - though you will never ever see that in a motion picture. The native contrast is 30,000:1 - which is significant.
-As far as the jump from DVD - you should see a significant increase in quality even over up-converted DVDs. Dynamic range and color reproduction are much more significant in blu-ray (based on the quality of the transfer). If you are watching something like Commando or Predator - the comparison is not SO different that those not looking for it would see significant difference. However, try a movie like Casino Royale or 3:10 to Yuma and you'll see it even if you're half-blind.
-The frame rates on blu-ray are not higher. In fact, many times they are lower - but usually converted to 60Hz by the television. blu-ray is capable of 24p (fps) playback - which is the same frame-rate as film. The TV will generally convert that to it's native 60Hz by using a 2:3 pulldown method. Displaying one frame twice, then the next 3 times and alternating.
-Also, "true DVD" is not 720p - it's 480p. The native res of a DVD video is always 720x480 MPEG2. If you're getting 720p from your Harmon Kardon then it must be connected via HDMI or component.
Hope at least some of this info is helpful.

1080p24p/60p 120 hz confusion...?
chris00780
i'm looking into getting a new sony lcd WITHOUT the 120hz option. i noticed that the sony lcd im looking at ( KDL-40S4100) has a 24p input option with blu-ray. does this mean that since it has a 24p input option with the blu-ray player that the need for a 120hz lcd is pointless? i understand the need for the 3:2 pulldown when you have a 60hz tv trying to display 24fps film. im just a little confused about this option with blu-ray. if this is the case, does this hold true for upconverted dvd's or is that where the need for 120hz lcd's comes in to play. thanks!!!
Answer
There are two advantages to the 120Hz:
1) Uniform motion of objects in the picture is much smoother, eliminating "trails". This is true for both video (60Hz) and film (24Hz) sources. This is a result of the interpolation of the extra frame from 60Hz sources. (For 24Hz sources, see below.)
2) if the set accepts 24p input, that works out to exactly 5 120Hz frames per one 24Hz movie frame, and that eliminates "judder". Judder comes from the fact that to convert 24Hz to 60Hz, one 24Hz frame produces 3 60Hz frames and the next will produce only 2 60Hz frames (3-2 pulldown). This uneven duration of display time causes non-uniform motion display. In addition, the 5 120Hz frames generated from the 24Hz frames are "interpolated" so that film "jitter" (the jerky display because of the slow frame rate) is reduced greatly.
In summary, if you are getting blu-ray, especially if you plan to watch a lot of film-originated material. 120Hz is the way to go.
The 24Hz output of a DVD player, both blu-ray and standard, can be a perfect replica of the original motion picture frame sequence. This is because the frames are "flagged" when recorded on the DVD, so it is possible for the circuitry to identify which frame to output at 24Hz and not output identical frames in sequence. So the 24hz benefits apply to both upconverted standard and blu-ray DVDs (played on a blu-ray player).
