Video Mode

 In the video interface you now have the same zoom button as in still image mode.

Like its predecessor, the iPhone 7 Plus is capable of recording 1080p video at 30 or 60 fps and in 4K resolution at 30 fps. In slow-motion mode you can either capture 1080p footage at 120 fps or 720p at 240 fps.

As before, video mode is selected on the mode dial on the main camera screen. You hit the red video button to start and stop recording and during the latter you have an additional shutter button for stills capture at your disposal. You can also switch between the two camera lenses by tapping on the new zoom button or apply up to 6x total zoom by combining optical and digital zoom. 

Other than that controls remain very simple. You can switch to the front camera and turn on the video light, but there is no control over video resolution or frame rates in the app itself. You'll have to go to the iPhone settings app to access those.

Video sample 1: 1080p video in bright light 

This video was recorded with the iPhone 7 Plus wide-angle camera in bright light. In these conditions the iPhone delivers very good image quality. The 1080p footage shows nice detail and image stabilization is excellent, allowing for extremely smooth hand-held panning. Despite a large number of moving subjects autofocus is very stable and sound recording quality is very good as well.

Video sample 2: 1080p video in low light

Image noise is quite visible in this night video but detail is still decent and motion very smooth. Again, the iPhone does an excellent job at stabilizing the image and the autofocus is very reliable in lower light conditions as well.

Video sample 3: 1080p video with the tele lens

Shooting with the tele-lens allows you to get closer to the subject in video mode as well. Again, electronic video stabilization performs extremely well, allowing for stable hand-held shooting with the 56mm equiv. lens. When recording this clip I was standing right next to a very loud speaker. It's very impressive how sound is recorded without any distortion or peaking.

Video sample 4: 4K video

When viewed at full size, the iPhone's 4K footage is not the sharpest we have seen but still offers considerably more detail than the 1080p footage, so is worth using if you can make use of the output resolution.

Video sample 5: Slow motion video

The iPhone 7 Plus offers the same 720p/240 fps and 1080p/120 fps slow motion modes as the 6s series. In the gallery app you can adjust where the video transitions from normal speed to slow-motion and back again, which makes for a very neat effect.

Unfortunately you still can't simply move the video file to your computer or onto a USB-stick to plug into your TV. Simply copying the .mov video file to a PC or Mac gives you a video that plays at 120 fps or 240 fps — i.e., it will look like any other video, except maybe a bit smoother. To share a slow-motion video you have to post it directly to YouTube, Vimeo or Facebook, save it to Google Drive or email it, which means the shared files might use a higher compression rate than the ones on your device.

The iPhone slow-motion mode is one of the best and can capture great results, we just wish Apple would make it easier to share them.
