Hej!

Jeg håber i kan hjælpe mig, jeg har et måske dumt spørgsmål.

Jeg har egentlig fin forstand på fladskærms tv, og mit nye tv (sony W905a), fungerer perfekt.

Dog har jeg hørt et sted, og kan ikke huske hvor, at det skulle kunne billedbehandle sådan at det viser højere end 24 fps, for at optimere klarhed og billedkvalitet, jeg kan dog ikke finde denne funktion i nogen af tv'ets menuer.

Ved i om det er sandt at det kan det, og hvis ja, hvordan slår jeg det så til? Hvis det i så fald ikke allerede er slået til. :)

Venlig hilsen Kenny.

Sony W905

MOTION - Sony’s motion-compensated frame interpolation system is called [Motionflow], which comes in 6 flavours on the KDL55W905A: “Standard“, “Smooth“, “True Cinema“, “Clear“, “Clear Plus” and “Impulse“. The first two introduced soap opera effect into 24p movies, so we rejected them immediately. For the sake of completeness, motion resolution (as determined through the horizontally scrolling test chart in the FPD Benchmark disc) were 850 and 900 for “Standard” and “Smooth” respectively. “True Cinema” did not increase motion resolution at all beyond the stock LCD level of 300.

The last three options increased motion resolution to 1080 lines. The “Impulse” mode uses backlight scanning/ black frame insertion techniques to “reset” our retinal persistence and improve the perceived clarity of moving objects. No interpolation is applied in this mode, so there’s no interpolation artefacts, but we did see some double edge ghosting on selected panning shots.

The Sony W905′s “Impulse” mode implementation caused significantly less flicker to our eyes compared to last year’s HX853, which is a massive plus. However, there’s still a sizeable amount of brightness drop: with “Impulse” mode engaged, we only managed to coax a maximum luminance of 98 cd/m2 out of the KDL-55W905A with both [Backlight] and [Contrast] bumped up to “Max“. This pretty much rules it out for daytime viewing when it’s arguably most needed, since most live sports broadcasts (which benefit most from higher motion resolution without interpolation artefacts) take place during the day.

[Motionflow] “Clear” interpolates without causing 24fps film-based content to look like hyperrealistic, ultra-smooth video. “Clear Plus” appears to be a midway setting between “Clear” and “Impulse” – there’s some interpolation going on, and a small decrease in luminance. Both “Clear” and “Clear Plus” are viable options to boost motion resolution without evident side effects, with the former being more practical for daytime use.

Det er kun et dumt spørgsmål, hvis du er klar over, at den funktion du efterspørger, rent faktisk forringer billedet, men ønsker den alligevel ;)
