led tv soap opera effect image
Eric W
I've seen a picture on an LED TV with 120 Hz refresh rate...and I can't quite put my finger on it, but something doesn't look quite right to me. Is it possible a refresh rate of 60 Hz looks more natural?
Answer
You could be noticing something that has been referred to as the 'soap opera effect' . This started showing up on 120HZ tv's that were designed to reduce motion blur or judder. The byproduct of this process created an unnatural look for movies.

What should I be looking for when buying a new TV?

Yes we still own those ugly pregnant TVs haha.
We're upgrading and I wanted to know what the best TVs are.
My dads refuses to look at any other company but Sony (bravia).
Someone I know recently got a Samsung smart TV but it was a really crappy screen display.
I know LCD LED over plasma any day I studied it in school but there is so many to choose from.
Which is best?
Answer
- Top brands: Panasonic (Plasma) > Samsung (LED) > Sony (LED) > LG (LED). Top off brands for LED: Vizio, Toshiba, Phillips.
= Plasma has best picture and audio quality. Plasma has least/no motion blur problems (less blur for more crisp/clear/higher resolutions and best contrast ratios for best color quality especially for blacks and best frequency/hz response times.ect). Newer Plasmas have improved their burn in problems by using technologies like pixel shifting/scrolling. Newer Plasmas haved improved their screen glare problems (and set vivid mode for bright rooms, has other picture modes depending on lighting of room). Newer plasmas use less energy consumption and last longer. Plasma are cheaper to buy, that's why LED is more popular because they want you to buy more expensive cheap made tv's (LCD is becoming discontinued because LED is a LCD tv with LED back/edge lights which improves many things like Plasma).
- I recommend 1920x1080 for movies, computer monitor/display, some tv shows, and some game console games and I recommend 1920x720 for some tv shows and some game console games. I recommend 40+ inches for movies and/or tv shows and 20-30 inches for computer monitor and 30-40 inches for game console games.
- FPS (frames per second): Every video consists of a number of frames per second, think of a video as a fast moving flip book. NTSC countries use 60i or 30i FPS (newer stations use 30p or 60p FPS) for tv shows. PAL/SECAM countries use 50i or 25i FPS (newer stations use 25p or 50p FPS) for tv shows. Movies use 24p/25p FPS (first movie to use 48p was LOTR: The Hobbit). Games use anywhere to 2 to 120 FPS (older games use lower FPS while newer games use higher FPS).
- TV refresh rate (measured in hz): Example, A tv with a refresh rate of 120 hz means it refreshes/flashes the entire screen 120 times a second.
- How do LED or LCD tv refresh rates work with the FPS of a video? (I recommend real/true 240hz refresh rate, some tv advertising may fool you by listing the fake interpolation or fake backlight scanning/dimming refresh rates).
- http://en.wikipedia.org/wiki/Motion_interpolation (Names of the new technologies for newer tv's at the link): Motion Interpolation or Motion Compensated Frame Interpolation (MCFI), is a form of video processing in which new fake frames are generated between existing ones to up the FPS of a video to reduce motion blur and/or for judder removal/judder adjustment. MCFI video processing may cause gamer input lag and/or artifacts such as the soap opera effect (may ruin the look of a video).
- Many tv's allow viewers to turn motion interpolation (MCFI) off. The tv repeats the frames a certain number of times to match the tv's refresh rate. Example; To display 24 frames per second on a tv with a 120 hz refresh rate, each frame is repeated 5 times every 24th of a second.
- But what happens if the FPS of a video does not match the refresh rate of the tv? Then you get a pulldown, a pulldown is what causes a jittery screen (aka judder) because the tv repeats the odd frames a different amount of times the tv repeats the even frames. Example; A 3:2 pulldown is post popular because it is needed to match a 24 fps video with a 60hz refresh rate tv, odd frames are repeated 3 times (12x3=36) and even frames are repated 2 times (12x2=24) and 36+24=60 FPS for a 60hz refresh rate tv.
How does Plasma tv refresh rates work with the FPS of a video?
- It will take each pixel in a frame and and repeat it a number of times based on the number of sub-field drives (SFD) the tv has with it's refresh rate. Example 1; (NTSC countries) 600hz sub-field drive/motion tv means 60hz FPS x 10 sub-fields per frame = 600hz refresh rate. Example 2; (PAL/SECAM countries) 600hz sub-field drive/motion tv means 50hz FPS x 12 sub-fields per frame = 600hz refresh rate.
- What is focused-field drive (FFD) on Neo-Plasmas? (Light switching speed = better colors and less motion blur) 2500hz focused field drive means sub-fields are virtually packed into 1/2500th of a second as a sharp impluse, creating crisp motion images even in very very fast movining images (FFD is defined as a inverse of light emission period t. 1/t = 1/0.4ms = 2,500 FFD). Regular sub-feild drives like 50 FPS x 12 sub-fields = 600 hz, light emission spreads as wide as 1 field time (1/60th sec) maximum which results in blurry images for very very fast moving images.
- Refresh rates on Plasmas work similar to LED/LCD tv's. These settings are usually automatic, but you can change them in the advanced picture settings, Example 1; 2D 24p FPS mode and choose refresh rates of 48hz/96hz or 30hz/60hz with pulldown (might use interpolation frames for pulldowns), Example 2; 3D mode and choose refresh rates of 96hz for 24 FPS or 100hz for 50 FPS or 120hz for 60 or 24 fps.ect Of course it has gamer mode or many other adjustments.
