Video Mode

As before the iPhone video UI is very clean, with the video button and stills shutter button the only controls. At the top the recording time is displayed.

Like the 5s the iPhone 6 Plus is capable of recording 1080p video but while the old model was limited to 30 fps the new device can capture 60 fps at full-HD resolution. There is also a new 240 fps slow motion mode at 720p resolution but the 6 Plus lacks the 4K video mode that can be found on some of its high-end Android rivals.

The video user interface is very simple and once the mode dial is set to video the controls are limited. 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. However, you can activate 60 fps mode in the camera section of the iPhone settings. After hitting the video button to start recording a shutter button appears in the bottom right corner. Pressing it captures a still image during video recording. Still are limited to 4MP in size and the 16:9 aspect ratio of the video footage though.

As before, the angle of view in video mode is a little narrower in video mode than in stills mode which indicates that in addition to the iPhone 6 Plus' optical image stabilization the camera is applying digital stabilization as well.

Video Sample 1: 1080p video in bright light

This video was taken hand-held in bright light. As you can see the footage is very smooth. The combination of optical and digital image stabilization is doing a very good job and the recording is very stable. When viewing at 100% detail is good and the image clean of artifacts. The focus performs well without any hunting. Sound recording is very clear.

Video Sample 2: 1080p video in low light

This clip was recorded hand-held at night. Again the stabilization and focus are working very well. On most smartphone cameras the AF has a tendency to hunt when shooting video in low light but the iPhone is very stable, even in very dark scenes. Luminance noise is noticeable in this clip but within acceptable limits. Exposure is good and, despite the high volume, there is no distortion in the sound track.

Video Sample 3: slow motion video at 240 fps

Slow motion video on the iPhone 6 Plus works pretty much the same way as on the 5s. However, in addition the 120 fps mode there is now a new 240 fps mode which translates to smooth eighth-speed motion when played back at the standard 30 fps. As before you can adjust where the video transitions to slow-mo and back again which makes for a very neat effect as you can see in the 568 x 320 sample below.

Unfortunately, like in iOS 7 you cannot export the full-resolution slow-motion 720p video file to your computer. 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 play it back in slow motion you have to edit it in a capable editing software on your computer. 

After recording a slow-motion video you can adjust the part of the video that actually plays in slow-mo by moving the sliders under the frame strip.

The easiest way of sharing a slow-motion video is to do so directly from the app. You can post your video to YouTube, Vimeo or Facebook or email it. However, the shared files are of lower resolution and with higher compression than the file on your device. The iPhone 6 Plus' slow-motion mode, especially the 240 fps variant, is great fun to play with and produces high-quality results but we would really wish Apple would make it easier to share those results in their full glory.
