basta vedere che nel VX200 (ben più performante e costoso) il deinterlacer è sempre quello.
Scusami ancora ti diventero antipatico pero dovresti rileggerti la rece del VX200 questo è il passaggio incriminato .....i segnali SD beccano un'eccellente
Video Processing
The performance of the VX200 in the video processing tests was excellent overall, with just a couple of minor issues. Using both the PAL and NTSC HQV benchmark discs the SMPTE colour bar test was reproduced correctly with the VX200 scaling the full 576i and 480i images without any loss of detail or unwanted ringing. The VX200 also scored very highly in the jaggies tests on both discs as well as performing very well on the diagonal interpolation test, with two of the three moving bars appearing smooth and only the bottom most extreme bar showing very slight jaggies. The VX200 also had no problems in resolving all the fine brickwork in the detail tests on both the PAL and NTSC discs, as well as correctly displaying the waving flag footage. This is important because with a screen this size you need excellent video processing to make standard definition images look acceptable.
Much to my surprise the VX200 managed to correctly detect 2:3 (NTSC - USA/Japan) cadence as well as correctly lock onto film based material in the film detail test (as long as the Cinema Reality function is on). This is the first time I’ve seen a Panasonic display do this but sadly it still couldn’t correctly detect 2:2 (PAL - European) cadence. However it is a step in the right direction and hopefully this will filter down to Panasonic’s consumer displays. The VX200 also performed well when displaying film material with scrolling video text and correctly displayed the words without blurring or shredding.
The VX200 also performed extremely well in most of the tests on the HQV Blu-ray using high definition content. With the player set to 1080i the display correctly deinterlaced and displayed both the video and film resolution tests (provided the 16:9 mode is correctly set to 1:1 Pixel Mode) and showed very good scaling and filtering performance as well as excellent resolution enhancement. The VX200 also had no problems in showing video text overlaid on film based material.
It is important to ensure that the Frame Creation function is left off, unless you want film based material to look like video and for the same reason you need to ensure that the 24p Smooth Film function is also turned off when watching 24p material. Once the 24p Smooth Function has been turned off the VX200 reproduces 24p material superbly with no motion artefacts or judder.
Using the Spears and Munsil test disc, we checked the high and low dynamic range performance of the VX200. The headroom performance of the VX200 was initially clipped with no detail above video level 235. However if you change the HDMI Range setting from Auto or Video (16-235) to Full (0-255) then the VX200 reproduces from reference white (video level 235) up to peak white (video level 255). Whilst technically video is supposed to be between video levels 16-235 in actual fact there will be peak information between video levels 253 and 255 so it is important that a display doesn’t clip all the way up to video level 255. In addition the VX200 showed picture information down to reference black (video level 17) which is good because we want to see detail below to video level 17 but nothing below it.
There was a lot of controversy last year relating to the processing of 50Hz material on Panasonic’s plasma range. After initially denying there was a problem, Panasonic finally admitted that the optimisation of their plasmas for 3D playback had resulted in some issues with 50Hz material. When we asked them about this problem in relation to their 2011 lineup Panasonic’s answer was a rather cryptic “we are always trying to improve our performance”. With the VX200 I used the moving zone plate test at 50Hz, 60Hz and 24p to look for any processing issues and whilst the problem was still there it was much less obvious than on previous displays. This is especially significant when you consider this is an 85” screen and it would seem that whilst not completely eradicating problem, Panasonic have indeed made improvements. This certainly bodes well for their 2011 lineup and we are looking forward to reviewing them in the near future.
Overall this is an excellent set of results and the video processing of the VX200 is very good with the notable exception of 2:2 cadence detection which Panasonic really needs to correct and some minor issues with images encoded at 50Hz.
Cerchiamo di mettere i puntini sulle i invece che fare disinformazione
