Thank you all for your extensive feedback. It is really appreciated. We of course regret that this topic has led to so many questions and discussions and herewith would like to give our view.
First of all, you need to know that picture quality, or how one perceives it, has many variables including source material (compression factor, bit rate), source device, source input, TV settings, software version, watching distance, etc.
This all makes it quite difficult to judge TV’s and to come to reliable, convincing conclusions.
The feature Natural Motion (as we at Philips call it) has been introduced to compensate the motion judder in, for example, MOVIE material. Those are 24 Hz recordings that need special processing to look good at displays with 50 Hz - or more - refresh rates (perfectly explained by "Petasis" in this post).
However, by doing this, side effects may be introduced. This is not different with competition and is linked to this kind of processing.
We have executed an extensive test on our own models (2012 6000-, 8000-, and 9000-series) and also were able to compare them with some of the equivalent competition sets.
For the test, all TV’s were set to their default picture settings (for Philips this means NATURAL smart mode, where Natural Motion is set to MEDIUM). They all were connected to the same source device and fed with the same source material.
As source material we used some examples you’ve referred to and some others:
1. “Bee Movie”: antenna scene,
2. “White Collar S01E01”: jail bar scene,
3. “Jessica Parker” (Star Trek),
This is what we found:
1. Playing the Bee Movie scene at 13m30 (where the bees lift off and pass their general), we see on all TV's the same behaviour like you reported: the general's antennas disappear temporary.
2. Also the scene with the jail bars in "White Collar" at 6m07, show exactly the same behaviour on all tested models: there are artefacts visible in the jail bars while they pass by.
Note that using the Natural Motion setting "MIN, enables the algorithm to detect these scenes", and prevents automatically the algorithm to operate on these particular scenes by falling back to the original input format.
3. This is typically a scene where Philips Natural Motion is outperforming competition on fast catch-in from the start of the movement.
4. This is typically a clip with fast motion where Philips Natural Motion is still capable of following the fast speed.
5. This is typically a clip with complex motion where competition models are trying to mask their problems by preventing the Natural Motion feature to operate and fall back to judder mode. Philips Natural Motion is holding longer.
As explained above, the noted effects are normal and expected behaviour.
They are a result of the incoming material, which has judder inside (24/25/30p film), and defined by the used picture processing technologies and choices made.
The fact that some of you experience this as a fault, cannot be acknowledged, and is really a matter of TV settings, source material, and personal perception.
There is nothing wrong with our television equipment and, compared to competition, Philips Natural Motion has certainly clear advantages in many scenes.
We really want to offer the customer the most optimal viewing experiences on their Philips flat TV’s, and in that extend we have noted down the specific scenes where some of you are complaining about and we are investigating whether we can even further improve on these. If this would be possible, we will bring this to all customers as a software update, further improving the performance beyond what we already offer per today.
Our final conclusion is that our 2012 models fully behave as specified, and are at least on par with (and in some cases better than) competition on Picture Quality.
Seriously though this was the answer I was expecting - are you able to tell us which competition sets you tried
