When it can't accuratley predict the in between frame or field it will exhibit a interpolated or blended image of the two. Another artifact is halo or a morphed image around things like the interpolated shot of Bruce Willis(look around his head the chain link fence is distorded around the front of his face) Now these artifacts on the converter are no where near as bad as what the LCD is displaying (the difference between a $100,000 converter and $3500 LCD monitor).
In a nutshell the conversion from 60 to 120hz on my Samsung xx71 isnt bad considering what its doing to achieve the 120hz. Could it be better, Hell yes, will they ever fix it? I think they will find a better way of minimizing the artifacts and call it a day. When whatching sports I turn off the AMP to minimize the artifacts. For games, There is a game mode that appears to revert to a 60hz mode (I cant verify this put it eliminates TBE). Thats my opinion and I'm happy with my purchase. If someone made a 52 inch or larger 16x9 CRT I'm sure we would all be on it.
Thanks for replying. For anybody wondering, Spectra18 works with the best frame-rate converters in the world
which is basically what AMP is - plus he has a 71
. I have a couple quesions when you have time:
For reference, the Samsung is rumored to use the micronas FRC9wxyM
1) In your opinion does the 69/71 use the same "motion vector process" as the Snell/Wilcox or the lesser "block matching method"
- I always assumed the latter as the former is mucho-expensive.
2) I made some educated guesses as to what happens when prediction fails. When you say the TV will "exibit an interpolated image" above do you mean "linear interpolation" (as in the man with 3 arms).
Is "blending" the same as "cut-and-paste.
3) There are a few other ideas floating around as to the cause of "TBE". You mentioned "interpolation". Does interlacing contribute? I think you said it did and i would agree. What about OreoJoe's motion vector idea above? Are these all causes?
4) Finally I'm glad your'e impressed with AMP. Do you think it has a future and do you think it will ever match snell/wilcox considering the price of that technology. (11 frame delay? - that would not be good for gaming ah). Do you think movies/TV will ever raise the temporal framerates so TV's won't have to?
