Video

Apple’s new H6 ISP brings with it a modernization of the video recording options for the iPhone 5s. The default video record mode is still 1080p at 30 fps, but there’s also a new 720p 120 fps “slo-mo” mode as well. In the latter, video is captured at 120 fps but optionally played back at 30 fps in order to achieve a high speed camera/slow motion effect. The result is pretty cool:

In the camera UI you can select what portions of the video you want to play back at 30 fps and what portions you want to leave at full speed. The .mov file is stored on NAND as a ~27Mbps 720p120 without any customizations, however when you share it the entire video is transcoded into a 30 fps format which preserves the slow motion effect.

The slo-mo mode is separate from the standard video recording mode, it’s the next stop on the dial in the new iOS 7 camera app. Video preview in slo-mo mode also happens at 60 fps compared to 30 fps for the standard video record and still image capture modes.

Adding high speed camera modes to smartphones is a great step in my opinion and a wonderful use of increases in ISP and SoC performance. I would like to see Apple expose a 1080p60 mode as well. Technically 1080p60 does require slightly more bandwidth than 720p120, but I’d hope that Apple targeted both in the design of H6 and simply chose to expose 720p120 as it’s an easier feature to market.

Standard 1080p30 recording is also available:

    I imagine he would say "I heard exactly the same shit about the A6 and how it couldn't possibly be as good as I claimed. Come back when you have NUMBERS to back up your complaints." Reply

    You are mistaking a more natural transition to a 64-bit mobile world with a "PR stunt." Yes, Android will probably make a huge jump and switch to 64-bit and include 8GB of memory, or something crazy like that, but will only add to fragmentation they are already burdened with. However, Apple is trying to avoid that by building steps that lead to where they eventually want the iPhone to go. Reply

    The PC market is fragmented as well, but is still goes, doesn't it? Surely, as a bigger ecosystem, android will be slower to adopt changes. But HPC doesn't really make sense in a phone, that is why most ARM chip vendors are focusing on server v8 chips and infrastructure, which will be more lucrative than consumer electronics. v8 is the future, no doubt about it, but apple has no other winning hand besides offering v8 a little too early, knowing they can make up for the cost of the premature transition with profit margins other manufacturers cannot dream of asking for the same hardware. Surely, other brands have their fanboys too, but nowhere nearly as fanatically devoted and eager to "just take my money". Reply

    I've never had any problem with this "fragmentation" that you cut and pasted from somewhere. How exactly has that kept you from buying Android? Do you normally keep your phone for 5 years or more? I'd be willing to bet you aren't using an iPhone 3 right now.. If you upgrade your phone every few years anyways, what do you care if the first generation Droid doesn't run the latest OS update? Reply

    The fact that there was never an iPhone 3 might have something to do with that. Reply

    As a programmer I say there is a HUGE fragmentation problem with all the Androids.
    I code for Jelly Beans only and I do have an "old" 4.0 mono CPU device for testing the lag.

    You lost me when you used the phrase "apple fanboys" and "declining sales". You don't seem to understand the difference between market share versus unit sales. Reply

    So you must have taken "apple fanboys" personally, and understandably "declining sales" in a context regarding apples conflicts you. Like all other vendors, apple sales drop, thus the periodic refreshes, which do need their selling points, this time around it is v8. In the past, apple resorted to similar strategies, like making exclusive deals, purchasing the entire initial batches of new generation parts, and again making up for the cost of this "innovation" with their profit margins.

    I don't recall any other brand which pushed kids to selling their organs, do you? If that is not fanatical fanboyism, I don't know what it is...

    Weird---seems to me EVERY time an iPhone is released, it sells MORE than the previous version FASTER! In fact, it's never been surpassed by another electronic item in history...and it's sales continue to climb. News Flash! Android (High end; S4/Note/HTC 1/XPeria) also sell @ a premium and almost @ the exact price of Apple's handsets. The rest of your post is nonsense. It's not just Anand's site and review praising the performance of the A7---it's ubiquitous. Is Apple paying Ars? TechCrunch? MacRumors? WSJ? Engadget? CNet?
    Dude---this is one HELL of an SoC. It's so much MORE than a 64bit chess match. A company licensing and building from the ground up a CPU/GPU/IPU that matches their OS and allows the tools to developers (For Free!) in XCode so the transition is seamless! The speed of this chip is awesome. Setting themselves up early is smart---the iPad release is imminent and has competition from both sides...Microsoft and Android. With a significantly larger 'body' and area to allow for more RAM...and future releases of other ARM based products, Apple is making in-roads within the mobile sector that ONLY bozos that cherish other brands, OEMs, or otherwise have some weird bone to pick with Apple can't realize. Mind blowing. I'm brand agnostic---use OSx, Windows and even own a couple of Android devices....but to me as dismissive as you are about the A7s build and putting it in a product the size of a pack of smokes is about as silly and should I say 'ignorant' a stance as I've seen in a long LONG time.
    This move by Apple is HUGE. Moore's law now attributed to mobile. Still a dual core. Still 1GB of RAM (albeit DDR3 vs DDR2)---yet doubling, tripling, sometimes quadrupling performance of the other 'off the shelf' SoCs on the market that other OEMs are using. It's no secret---Apple has been hiring and head hunting chip designers from Intel and AMD for some time now. These guys and gals are some of the brightest minds on earth....but you've got it all figured out and somehow Anand's been blinded by the conspiracy---as has EVERY other reviewer on the 'net.
    Un-Believable.
