Use the Highest Quality Available on Your iPhone
Most modern iPhones can take amazing video at resolutions up to 4K at 60 frames per second (fps). While that might be too much for some folks, if you want to take amazing videos, you’re better off using the highest settings your iPhone can support.
To change the resolution on your iPhone, you need to do the following:
- Open the Settings app.
- Scroll down and go to Camera.
- Tap on Record Video.
- Choose the highest resolution possible. For instance, 4K at 60 fps (High Efficiency).
Keep in mind, though, the greater the resolution, the more space each video will need, so be sure you have enough storage.
