Time to raise some doubts.....
Pardon my poor description, but I'll try to explain. "Cinemotion" and "24p True Cinema" are kinda related, but they're really very
different animals. Movies and many TV shows are filmed at 24 frames per second (fps or Hz). Over-the-air (OTA) TV is broadcast at 60Hz and most TV's to date have displayed their images at 60Hz. In order to broadcast 24fps content for view on 60Hz TV's, the framerate has to be changed to 60 Hz via a process called telecine
or 3:2 pulldown
(because 24 won't multiply directly into 60). Blu-ray movies (for example) are encoded on the disc at 24fps, but the players also have had to process the signal to 60Hz for view on most displays. The Holy Grail for many videophiles has been the ability to take that raw original 24fps source and display it on the screen without
the telecine processing/conversion to reduce artifacts like telecine judder
.24p True Cinema
is Sony's name for their process whereby their 120Hz displays (like the A 3000) take an original 24 fps source (like on a Blu-ray disc from a player with the ability to output that raw 24p signal) and display it on the screen without further processing
with 3:2 pulldown (24 multiplies directly into 120)-that "Holy Grail" of many videophiles that I mentioned. Some recent 120Hz displays from other manufacturers apparently saved cost in their processors by taking 24fps input, converting it to 30Hz with telecine, and then multiplying it by 4 to 120Hz- thus reintroducing artifacts caused by the telecine process. Sony's 24p True Cinema supposedly "does it right" and eliminates the telecine process on 24fps sources. (And maybe
the new displays will even do a better job of recovering the original 24fps content from telecined broadcast sources like movies and many TV shows from OTA broadcasters because of its 24p True Cinema.)Cinemotion
is Sony's name for their reverse 3:2 pulldown (reverse telecine) processing necessary to display a telecined source (e.g. OTA broadcast) on the screen (see pg. 37 of the A3000 manual). "Cinemotion" is what the display uses to process telecined 24fps content, "24p True Cinema" is what the display uses to display 24fps content without
subjecting it to telecine.
Sony provides serveral different settings for the Cinemotion on its A3000's so you can optimize the picture on sources that have undergone 3:2 pulldown processing. There is no need to change settings for the 24p True Cinema feature- the lack
of telecine processing just "happens" when you feed the display a 24fps source.
