The Sopa Opera Effect or Why I Prefer Plasma Over LCD
We live in this world where LCD TV manufacturers are obsessed with advertising 120/240Hz refresh rates packaged with motion interpolation effects. The 120/240Hz refresh rate is fine for judder reduction. Using a 120/240Hz screen and applying a whole number 5:5 or 10:10 frame repeat does a good job of reducing the film judder and preserving the original image integrity. The problem are the motion interpolation effects (sometimes branded as "Precision Motion"). On a 12 Hz TV with the motion interpolation turned on, this means that 4 out of every 5 frames displayed on the TV were artificially filled in by the TV's video processor, not native to the source. That creates the "soap opera effect". In other words, it makes something originally shot on a 35/70mm film camera look like it was created on a cheap camcorder. That's why I still prefer a PLASMA TV. PLASMAs don't suffer from this kind of problems.
