This is where I am right now with Cinemotion:
First, quoting from the xbr user's manual (sony obviously went to some effort to explain it in the manual, so for agrument's sake, let's assume the following is correct):
"Select Auto1 or Auto2 to automatically detect film content and apply a reverse 3-2 pulldown process. Moving pictures will appear cleaner and more natural looking. Select Off to disable the detection".
So, Cinemotion is there to automatically detect the presence of "film content" (24p???). When detected, the TV will apply a reverse 3-2 pulldown (meaning that deinterlacing is performed to remove the extra inserted frames to get back to 24p or the original frames???). I think this is what Sony has been advertising as their "24p True Cinema" technology.
So, Sony has given the end user (us) two algorithms for true cinema 24p: Auto1 and Auto2. The difference? Auto1 is used in conjuction with Motionflow to give the user greater control over the images we see. If it's an action-packed film with lots of fast-moving scenes (e.g. Matrix, Tokyo Drift, Spiderman, etc.), use Auto1 and adjust Motion Enhancer (ME) according to your likes. If you're watching low-action films such as Beaches, chick flicks, etc. use Auto2, which disables ME completely and applies an algorithm best suited for that content (low action).
So far, I get it.
What I find confusing is what does Cinemotion do to non film-based content
(i.e. SD, upconverted HD, etc.)?? It's just my opinion, but where Sony has failed to be explicit, is defining what some of these settings do with different input sources. That's why when folks post their calibration settings, I think it's very important to specify on what source they calibrated it on.
It's obvious to me that the Cinemotion/MotionFlow settings affect SD and 1080i content because I can see the effects on screen. But Sony doesn't say much, if anything, about that in their doc. This is where I'm hung up.
If Cinemotion is there examining the incoming source looking for "film based" content, what is it doing to the picture the rest of the time while it isn't detecting film based content and what effect does it have on PQ???
Please correct me where I'm wrong.
