![]() In the past few years we've been pushing the technology envelope pretty hard-trying to get higher frame rates, greater resolution, more dynamic range, more bit depth, more throughput/bit rates and RAW.įirst-let me discuss the 3D HFR projection. This is precisely why one should shoot at 1/50th of a second on their HDSLRs and use ND or neutral density filters to makes sure they don't have too much depth of field and can also ensure they aren't forced into shooting at higher shutter speeds. When we test at CNET Labs we always try to listen to the highest-quality streams, and prefer uncompressed hi-res where possible.The reason the standard film projection rate of 24 frames per second works so well, is that it's just a few frames faster than what the brain needs in order to be tricked into seeing what are effectively still images, appear to move on screen-it's called the "Persistence of Vision Theory." In tandem with that important theory, he motion blur you get by shooting at 24 fps and (on a standard 180 degree shutter) at 1/48th of a second, is just as important in making something look "cinematic" as the lack of depth of field we get by using larger sensors, and bright lenses at large apertures. If squeezing the maximum amount of detail out of your hi-fi system is a priority, this may be a deciding factor. If you're an audio quality nerd there's one difference between the two streams, and it's a numbers thing - AirPlay/AirPlay 2 are stuck at CD quality (16/44) while Chromecast allows up to 24/96 streams. ![]() In our time using both systems there have never been any noticeable problems that didn't involve internet or Wi-Fi connectivity. Tap the AirPlay or Chromecast icon and your media plays. In practice, using either system to stream content day-to-day is mostly invisible - your equipment simply appears in whichever app you use. Apple's system is noticeably slicker, while Google's looks like a middle-school quiz, but both apps get the job of connecting your devices done. The systems use similarly named apps to set up new devices:Īnd Apple Home. ![]()
