Great Features For Video Creators On iPhone 7


My first reaction to the launch of the iPhone 7 was anger that Apple had removed the 3.5mm headphone jack. Two days on I’m still not convinced it’s the right move for users but I’ll admit the phone seems to offer the vlogger or video maker some great features.

A lot of the initial reports have been about the dual lens system on the iPhone 7, in fact that only applies to the iPhone 7 Plus. The smaller iPhone 7 is only equipped with the wide angle f1.8 lens. Both versions being able to shoot 1080p footage at 30 and 60 fps.

If you missed the iPhone 7's launch in San Francisco here's the BBC report of the event.

 


Both versions of the phone seem to offer plenty to today’s video creator, although we will have to wait until 16th September 2016 before we can get hands-on with the phone. Until then here’s what Apple say we are going to get.

Better low light performance

Both the iPhone 7 and iPhone 7 Plus have a new 12-megapixel wide angle 28mm f/1.8 six element lens. According to Apple this will transmit about 50% more light to the sensor, compared to the iPhone 6s. We will need to wait to see what that will mean in practice but I think it is safe to assume that shooting indoors without video lights will be easier.

High resolution video

The iPhone 7’s 12-megapixel rear facing camera will give video creators the capability to shoot 4k footage at 30fps. Personally I haven’t bought-into the 4k hype. Most people just aren’t watching on 4k devices nor is 4k critical to your storytelling. However, once you transfer your footage you your computer 4k does allow you to reframe your shots by selective cropping without losing clarity in an HD timeline.

Slow Mo

The combination of that new camera and the A10 quad core processor will enable video creators to shoot at upto 120 fps at HD1080p or upto 240 fps at 720p. If you are into creating slow motion movies, you will obviously like this feature.

Better front-facing camera

The front facing camera has been upgraded to 7 megapixels. For the vlogger that’s great news. Until now, if you wanted to shoot yourself in full HD1080p you had to use the reaer camera and get a friend to frame the shot for you, monitor the phone’s screen in a mirror or do it by trial and error. With a full HD front facing camera it’s eezy-peasy to make sure you have framed yourself correctly.





Steady on – It’s got optical image stabilization

To get good blur free results I have always had to put my iPhone on a tripod. Now things should literally be clearer in hand held shots since the iPhone 7 is shipping with what Apple call cinematic video stabilization, available at both 1080p and 720p. Combined with the f/1.8 lens we should see crisper footage at lower light levels.

Optical zoom

If you go large and opt for the iPhone 7 Plus then you get not one 12-megapixel cameras but two. Alongside the first with a wide angle 28mm f1.8 lens you get an additional one with a 56mm f2.8 lens.

No doubt the new dual lens system is the result of Apple buying LinX Imaging in 2014. LinX Imaging specialised in multi aperture imaging and managed to solve the problem of successfully combining multiple images taken simultaneously. This technology has enabled Apple to give the iPhone 7 a so called optical zoom. The combination of a wide angle lens plus a telephoto lens means you now can zoom up to 2x without losing image clarity. Upto 6x digital zoom is also available. Other companies have been working on the same thing, such as the Corephotonic dual-camera, which you can see in this video from cnet. In fact the technology look very much like the iPhone 7 Plus.


That’s a great improvement for the iPhone video maker. For a start, it will make framing much easier. Until now you either had to physically move your camera back and fore to frame the shot or use the digital zoom and accept a loss in resolution. Now the video maker has much more flexibility. Set up your camera so your framing is approximately correct and then get it spot on with the optical zoom. Brilliant!

LinX Imaging used to claim their technology could deliver "stunning color images and high accuracy depth maps" producing images of SLR quality but without the bulk of an SLR.

By the way. The work LinX Imaging was doing, before Apple bought the company, allowed them to increase sensitivity for better image detail and reduce exposure times to reduce motion blurring. All of which sounds familiar from earlier on in this post.

What next

Apple make no mention of this but the LinX technology does more than provide optical zoom and improve low light performance. Because the LinX technology can produce depth maps from a single photo (using multiple apertures, like the iPhone 7 Plus), the information can be used to produce 3D point clouds of objects. There’s a tantalizing possibility that the iPhone 7 Plus (or a future iPhone) could create 3D scans of objects, to refocus an image with a synthetic depth of field effect and possibly eliminate or add objects to the image. If the phone can do that I might even forget about that missing 3.5mm headphone socket.
