Let’s build up some facts to determine the image processing with the Sharp 735 and the Elites:
AquoMotion 240 Technology improves fast moving images by combining Sharp's 120Hz Fine Motion Enhanced Technology with 120-backlight scanning. Fine Motion Advanced processing creates and inserts 60 unique frames a second, which smooths out edges that occur between frames in the original footage. The backlight scanning works with the panel refresh rate to further reduce perceived motion blur and improve overall clarity and picture quality.
Film Mode/3:2 pull-down (Sharp Owner’s Manual)
Automatically detects a film-based source (originally encoded at 24 frames/second), analyzes it then recreates each still film frame for high-definition picture quality. Advanced (High)/Advanced (Low): Select a desired level to remove jerkiness from film contents.
Standard: Detects, analyzes, converts film source.
Off: Normal viewing mode.
Three-Two Pull Down
Three-Two Pull Down a term used in filmmaking and television production for the post-production process of transferring Film to Video. Film runs at a standard rate of 24 frames per second. The NTSC video signal frame rate is 29.97 frames per second. Every interlaced video frame has two fields for each film frame. The three-two pull down, is where the telecine adds a third video field to every second video frame.
The trained can see the addition of this extra video field. When transferred back to film, it seems as though the third video field does not exist, but it will bring the rate of 30 frame/s back to 24 frame/s for film editing purposes. The reason for this is to keep image and sound in synchronization with one another.
Frame interpolation Claimed side effects (Wikipedia)
A few side effects can be introduced by the use of the technology. Motion interpolation on certain brands of HDTVs is sometimes accompanied by visual anomalies in the picture, described by CNET's David Carnoy as a 'little tear or glitch' in the picture, appearing for a fraction of a second. He adds the effect is most noticeable when the technology suddenly kicks in during a fast camera pan.
Video look or Soap Opera Effect (Wikipedia)
The "video" look is a byproduct of the perceived increase in framerate due to the interpolation and is commonly referred to as the "Soap Opera Effect" after the way those shows looked, having been shot on cheaper 60 Hz video instead of regular broadcast equipment or film
. Not everyone likes the effect and some complain that it ruins the cinematic look of home movies. For this reason, almost all manufactures have built in an option to turn the feature off.
The Sharp’s Aquomotion 240 scanning backlight interpolates/creates new frames at a 120Hz rate.
For video sources take the camera’s 30 original frames then let the Sharp’s fine processing create 30 more. Then repeat each one of 60 unique frames twice to output 120Hz.
For 24Hz film sources there are several similar possibilities. The simplest is with Aquomotion turned off. Repeated five times to create 120Hz (5:5 pulldown). The Aquomotion “Low” and “High” must create more unique frames than the original 24. However 24 does not divide into 120 evenly. To compensate, the motion algorithm knows how much time has elapsed from last frame display time to the time this new one will be displayed. The higher the frame interpolation rate the smoother the motion. However the faster the motion (and the more unpredictable it course) the more chance there is for noticeable errors to momentarily creep in.
True 240 Hz processing would reduce chances for errors. Even better will be when the Studio begins to shoot at higher frame rates like 48Hz.
I never use the Sharps Film mode with Aquomotion as it causes frequent motion judder ("jumpiness" in the picture). To reduce LCD blur (watching pixels change state on the screen) my personal preference is to use Aquomotion 240 exclusively. Unlike some other manufactures Sharp does not offer separate blur and judder controls. So season to personal taste.
