"Signal to Noise...
When "noise" has enough structure, it might fool DVP's "don't look at noise" detectors.
Artifacts of compression and even grain can all become "interesting" structure.
The movie 300, might be best left alone for this reason (highly stylized artistic intent reason too).
Hi Def mode has detection that does the best job of causing the DVP algorithm to ignore "noise" structure.
The vast majority of video frames where there is nothing of interest in part of the frame: sky, wall, flat smooth surface, etc. DVP will not process that area at all. You can pause and A/B most frames and see this to be true (pretty fancy AI goes into selectively NOT processing the entire frame). That being said, there will be pathological cases and we apologize for not being perfect...yet.
Low Quality, Low Resolution Video...
Bad video contains artificial structure in areas that you would NOT normally be looking at, which can be tempting for the DVP algorithm, as Full Pop mode does not have the detection mode engaged. So Full Pop Mode will sometimes attempt to process "interesting noise." The issue of that happening will come and go depending upon the content.
On the other hand, bad video contains so many problems already, that the eye/brain will accept some of the DVP errors, because the content needs so much help. DVP artifacts are often trivial compared to what the eye/brain has to deal with given the artifacts of compression. Also, DVP artifacts are often hidden in low quality material, due to all the other artifacts.
Full Pop Mode is the best mode to use on low quality low resolution material because it forces DVP into the image strongly enough that you often get a change that your eyes/brain notice and thank you for.
High Quality, Hi Resolution Video...
Very clean video (CGI and end to end HD with good encoding bit rate for playback media) will absorb an amazing amount of DVP Full Pop, particularly if it is hi fidelity with organic structure content. Round shapes and textures of all sizes, object separated in many depth planes. Avatar is a good example of all that mix.
Higher levels (60-90) of Hi Def mode will be tolerated and the virtually artifact free result can be seen to its fullest.
The greatest example I have witnessed is uncompressed D5 tape (DVP post processed on movie frames then encoded to uncompressed video) of a feature movie test segments (A Knights Tale) on a studio reference monitor at FotoKem. Astonishing!, and too bad we all cannot have that quality in our homes.
Medium/High Quality, Hi Resolution Video...
This is where many are in their living rooms, families sitting around and wondering why you won't stop A/B'ing the image or why you won't turn that damn sliding line off.. Use judicious amounts of DVP, Full Pop in low 30-60 settings or Hi Def or Gaming Mode 40-80. Hi Def and Gaming Modes you have noise/artifact detectors engaged and you will have a wide range of settings to play with, or set and forget just below a level that you feel causes some artifacts to creep through.
High quality compression codecs are appreciated by DVP and with enough success maybe DVP will contribute its own."
So, it seems again to come down to just what source material you're sending through the Darblet. I don't think the idea of set it, forget it -- even if you're only using it for a single source device will be satisfying all of the time. Just too much variation in how the content is captured and delivered. Even in a single film like Michael Mann's "Collateral", where he uses both film and high-def camera, may pose a challenge in finding the right mode and degree of Darbee to use (gotta' load that Blu-ray up and test).
