How to change your iPhone video resolution settings
In case you’re running any iOS since iOS 9 on anything from an iPhone 6 to the new iPhone 8 Plus, you can change what resolution the back camera records video at. A lower-quality setting can be the approach in case you’re low on capacity, or on the off chance that you basically needn’t bother with each one of those additional pixels.
Then again, on the off chance that you need to truly expand your video, the best way to shoot in 4K is in the settings menu, not simply the camera application. You can do this for both slo-mo videos and standard video accounts. Doing the switch is quick and simple — here’s the ticket.
Go to Settings > Camera, tap either Record Video or Record Slow-mo, and select your favored resolution from the recorded choices.
iPhone video resolution
Change the video resolution to account for more videos on your telephone.
Remember that the higher the resolution and edge rate, the more space the completed video will take up on your iPhone. For example:
Standard video recording
720p HD at 30fps: 40MB every minute
1080p HD at 30fps (default resolution): 60MB every minute
1080p HD at 60fps (smoother video): 90MB every minute
4K at 24fps: 135MB every minute
4K at 30fps: 170MB every minute
4K at 60fps: 400MB every minute
Slo-mo video recording
1080p HD at 120fps: 170MB every minute
1080p HD at 240fps (most edges, default): 480MB every minute.
