thanks for the insights mga brader. ung 24p produced by my total media theatre 5 (PC) doesnt really looks different from the normal 60fps by powerdvd, well maybe i dont have a keen eye for this and as long as it wont bug down my tv im ok
Don't worry about it. 60p is still the best so far.
Ang 24p tech, palpak pa rin up to now.
so what's this thing called 'True Motion plus' and how does it differ from the technology called 'Motion Flow'?
Motion Plus and
MotionFlow are not technical terms, but commercial names from manufacturers for marketing purposes.
The technical term is "Motion Interpolation Technology".
Samsung's name for its proprietary motion interpolation is "Motion Plus". Sony names its tech as "MotionFlow".
Panasonic calls it "IFC" (Intelligent Frame Creation); LG calls it "TruMotion"; Toshiba calls it "ClearScan"; Philips calls it "HD Digital Natural Motion".
Motion interpolation generates intermediate animation frames and inserts those generated frames in between original frames. If there are 24 frames per second, the software produces intermediate frames by guessing how those in-between frames would look like, to produce a total of 120 progressive frames per second.
For example:
3 original frames. Motion interpolation tech generates 2 additional frames and inserts them to produce 5 frames total.
Therefore, only the 3 original frames are real. The 2 additional ones are fake, generated by the software
. You can imagine the potential for processing errors. I'm sure sasablay yan, if the action on a given scene is very fast, or if you have a very long scene with continuous camera pans.
can a LCD tv with only 60hz refresh rate be integrated with this 'True Motion Plus' feature?
Don't call it "refresh rate". The term started with CRT monitors, sometimes called the "horizontal scan rate". The term is not applicable to LCD screens, but it was mistakenly carried over to LCD due to common usage.
60Hz format is a progressive NTSC video frame rate. You need a higher frame rate if you're going to insert additional frames into 60Hz. So if you have motion interpolation, the frame rate should be higher than 60Hz.
Motion interpolation usually uses 120Hz & 240Hz for NTSC sources, since 120 & 240 are divisible by 60 (NTSC) and divisible by 24 (frame rate of film). Motion interpolation for PAL sources usually use 100Hz & 200Hz, since 100 & 200 are divisible by the progressive PAL frame rate of 50p.
