I think many people on this forum are expecting way too much out of motion processing. Read further if you are interested.
I would like to point out something that was only covered very slightly in the 71 thread. Adding artificially created data to a data stream is not going to improve the quality of that stream. It is not possable. Information is either collected or lost at the point where it is recorded. You can not add more in later buy guessing, even if it is educated guessing. The best possable case is to get back what you recorded in the first place.
This brings up a very important question: Why have AMP at all.
Well the idea is to reduce motion blur, and or remove judder (not stutter). The motion blur part is questionable in my mind, because the pixels must have a fast response time in order for the tweened, or added frames to reduce blur. But blur is caused by the lack of pixel response time in the first place (catch 22). I think what they are trying to do is force the pixels to change in the right direction faster by updating them between frams. This might help if you could guess at the tweened frames with 100% accuracy, but you can not.
It looks like most people in these threads have over looked some basic principals of inturpolation. It is a mathematical estimate (guesstimate). The accruacy is limited by the algorythm and the samples used by it. The accuracy decreases dramatically when data behaves in unexpected ways or is far away from the orignal samples.
Example: If you have an object moving through a scene at a high rate of speed it may not have been picked up in your orignal samples, but it could have moved through your tweened fram so it will not show up when it should have, or it could show up when it should not. Sound familiar.
I believe that TBE is a side effect of the inturpolation algorythm not the processor or the firmware. I really doubt you can get rid of it without adding a lot of complexity to the processing and/or number of samples which would result in more input lag.
Why use AMP for gaming. Seriously; I do not get it. What is expected. all you are doing is tweening the frams generated by your computer with limited accuracy and added input lag. If you really want to game at 120 Hz you need something like a CRT with pixels that can respond that fast and a killer rig that can run the game loop at that rate. There is a reason that Entertainment or Game Mode runs at 60Hz, because that will give the best results.
Where to use AMP?
Animation is a perfect case, because the animated frames are usually created by tweening in the first place. that why we get so many reports of how good they look.
Movies are a good candidate, because AMP can remove the judder caused by 24fps camerias and smooth out other issues. I am sure there will be exceptions to this.
Cable/Satelite: We need a video engineer to analyze this one. Deinterlacing is basically decompression so some information must be lost in transmission, and I do not see where AMP fits in here. I would say you have to try it on a case by case basis.
The hole point of this neverending rant is; don't expect too much from any motion processing from anybody on any processor. Just experiment with it and use it where it works best.
I would love to see somebody do a faceoff between the 71 and A650 with AMP turned off on both. I would really like to know if the new pannel is really better in pixel response time.
Have fun with whatever you buy
