Apple today updated its iMovie app for iOS devices to version 2.2.1, fixing several bugs and adding 4K support for the iPad Air 2 following yesterday's release of iOS 9.1. An iPad Air 2 running iOS 9.1 can now be used to edit and share 4K resolution videos.

iMovie first began supporting 4K video editing with the 2.2 update released in September after the launch of the iPhone 6s and the iPhone 6s Plus. The two new iPhones are the first Apple devices that are capable of capturing 4K video, and along with the iPad Pro and the iPad Air 2, they're also the only devices that can edit 4K video.

Today's 2.2.1 iMovie update also includes several fixes for bugs that were discovered after the major 2.2 September update.
What's New
- Create and share movies at 4K resolution on iPad Air 2 with iOS 9.1*
- Fixes an issue that could prevent users from creating new trailers in some languages
- Resolves issues importing and removing projects from iCloud Drive
- Addresses interface issues that could appear in some right-to-left languages
- Addresses interface issues that could appear in iMovie extension for Photos
- Performance and stability improvementsiMovie supports 4K on iPhone 6s, iPhone 6s Plus, iPad Air 2, and iPad Pro
iMovie can be downloaded from the App Store for $4.99. [Direct Link]

Very strange that Apple is pushing 4K editing but is omitting 4K playback for the new Apple TV. What's up with that?
It is sort of funny. Apple seems to be going all in on 4K. The ATV omission is glaring when placed against the backdrop of the rest of their product line up. Minus the obviousness of the watch, the ATV omission seems strange.
 
Hm. The first thing an iPad Air 2 can do that an iPad mini 4 can't? At least in terms of Apple's own apps.

While the Air 2 and Mini 4 share the same A8 architecture, it's still "only" a 2GB of RAM version of what's in their iPhone 6 and 6 Plus, it's not as powerful as the A8X in the Air 2.

The Air 2 is truly a beast of a tablet, don't see me ditching mine for quite some time.

From what I can see, Apple's released 4K support is H.264 only. This is fine for the bitrates you can have with local storage, but in order to stream 4K reliably for the majority of Internet connections, you need H.265 or beyond. There's been no evidence of 4K H.265 support in any Apple product to date, and, like MPEG 4, people might decide it's not good enough.

Probably getting ready to next year :apple:TV.. Right now 4K is just like a baby growing.. Pushing 4k on iphones.. Editing videos.. We can forecasts that By next year 4K is mainstream. 4K netflix.. 4K HBO.. More 4K movies streaming.

Out of total ignorance, is the ATV lack of 4k an OS or hardware issue? Except for my ipad air 2 now, I don't actually have anything that supports 4k (and won't for a while), so it really doesn't matter to me, but I would like to understand the issue a little better.
 
it may support 4K editing but it does not display 4K content ( at its native resolution) on the air 2 for obvious reasons. Would the A8 processor have enough power to push 4K (4096 x 2160) out to a television?

I am less than knowledgeable in this arena. One would think if a small company like Roku can do it, Apple could do it as well.

Above my head honestly. Although there are TV's, Blu Rays, and streaming devices that have the 4K capability, I don't know if they are H.264 or H.265. Still the question remains. Apple adds the capability to shoot 4K, edit 4K, and view 4/5K screens, but the ATV just sits out there as the odd duck. I've no clue why, but the H.265 theory doesn't feel like it's the reason. I could be wrong.
 
This app is 616MB to download on my 6s. Hasn't App Thinning been fixed and applied yet? Or was it even larger before iOS 9.0?
 
Yesterday when I launched iMovie for the first time in quite a while on my 6+ it told me it was able to edit 4K video.

It's a 6+, not a 6S+. I just launched it again to double check it really says it can edit 4K video, but I don't know how to bring the introduction screen back up now that I've dismissed it once already...

Anyways, either Apple made a mistake saying I can edit 4K video, or this article made a mistake leaving off the 6+, or Apple made a mistake in including 4K support for the 6+ (like they made the mistake of allowing me to move my cursor with a two finger gesture in iOS 9 Beta 1. Freaking sucked when they removed that ability.)

Most of that 616 MB is content, like the cutscenes of kids frolicking in the forest and generic soundtracks. App thinning doesn't apply there. iOS has delta updates as well, suggesting Apple updated the content.
 
4K is not a limit for very recent Macs with Iris Pro graphics, or Macs with dedicated graphics of larger capacity or MacPros. To get an AX chip to support it is a generation or two away. In the mean time you can capture it in 4K and display it in HD (1K). I suspect the displays to really tell the difference with 4K that don't cost $2-10k are a generation away too.

Yes I know there are commodity displays that claim to be 4K, but one has to read the fine print to see if it is scaled or can display 4K but has no means to actually import it properly.

I believe it has to have HDMI 1.4a (whatever that is). I think even dual display link does not support it.

It will not be until an AppleTV supports 4K that it will be fully mainstream. Netflix offers it now to the extent there is content. So Apple is still a trailing edge adopter.

Rocketman

People are remaking C64 and Amiga boards and cases. That's retro.

I saw Toy Story 1 at El Capitan Theatre on release in 1K HD. Boy was that pixelated. But it was "digital".

Current digital theatrical is 4K. It needs to be 16K+. Red has been capturing that for 4 years.

Software. The A8 can push H.264 (and assuming 265 as well) 4K content fine, but it needs to be enabled in software.

Theoretically, the mini 4, 6 and 6 Plus could all support 4K editing but I think Apple kept these devices from doing it because the aren't as powerful as the A8X and A9 chips. Remember, the A8 only has a dual core CPU and a quad core GPU. The A8X has a tri-core CPU and octo-core GPU, while the A9 has a more efficient dual-core CPU and hex-core GPU.

It had the same splash screen on my Air 2, but it said that it's only on compatible devices. Surely yours said the same thing?

It might, but after reading threads of people saying how the iPhone 6+ has some choppiness with displaying 1080p, I wouldn't be so sure the chip can push a smooth 4K to a TV, alot would depend on the GPU.

The lag isn't because of the display, it's because the phone renders the OS at 1242x2208 then downsamples to 1080x1920. If they were using a true 1242x2208 display, it probably wouldn't have any lag.

native 4k (4096 x 2160) is quite a bit higher rez to render than 2208x1242,

but looking at this article, it does appear the A8 can support it.

not sure why they wouldn't enable it right out the gate though with the new Apple TV and with the iPhones being able to record 4k
