The iPhone 6S and 6S Plus are available for recording 4K high-definition video.
The iOS camera application on iPhone 6 and 6s are set to record video at 1080p at 60 frames per second. But ypu can enable 4K high-definition video by following these steps.
There are steps to enable or disable 4K video capture on iPhone 6S, 6S Plus
- Open the Settings app.
- Tap on Photos & Camera.
- Under the Camera section, tap on Record Video.
- Tap on 4K at 30 fps.
If the default 1080p will use 200MB for every minute of video captured the 4K video use almost double, it takes 375MB of storage for every minute you take. So, 4K video and 16GB iPhones are not going to get along at all.
You can identify what capture setting is currently active if you launch the Camera app, select the video mode, and look at the next the shutter icon. A small white box, complete with the current setting will be appeared. Unfortunately, you have to go back into Settings if you want to adjust recording quality every time you want to change it.
