Conclusion
The correction of the rendering of videos is just at the beginning of its life. We noticed, however, that only the correction of SD sequences like DVDs was activated. The next step will be, as this document provided by NVIDIA shows, to implement it on HD videos:
According to NVIDIA, the correction of HD videos will be less impressive than for SD videos (the correction is activated for all SD sequences: MPEG 2, DivX, QuickTime...). It seems to be a logical choice indeed as we start with a much higher level of precision in HD. Nevertheless, even with sequences encoded in 25 Mbits/s, we continue to see the twinkling effect. This implementation will be appreciated.
In a nutshell
It doesn´t often happen, we really like this function. Yes, the correction of the rendering of videos is a good thing and yes it compensates for the downsides of many LCDs that tend to overly accentuate a sequence’s compression imperfections. We also draw your attention to the fact that these imperfections aren´t something that you have to undergo. The encoding quality isn´t the only factor responsible for noise. Those who still have a CRT and the owners of P-MVA 8 ms will also agree with this fact. If the twinkling effect is still present in recent monitors, we will make do with this improvement.
Regarding the ATI vs NVIDIA duel, our preference goes to NVIDIA (here a Point of View GeForce 7800 GT). After a couple of manual adjustments, we ended up with a much more efficient correction than with the ATI (ASUSTEK X1800 XT). We would really like ATI to give us more latitude in the choice of parameters. Let´s hope that this personalisation will be included in a future version of drivers.
