The most common problem that causes your videos to be grainy is that you shoot them in areas where there’s low light. The darker your environment, the more your picture is going to come out grainy.

To stop this, you have to try recording your videos in places where there’s an excess of light so your camera can focus properly. This will help reduce the grainy video effect on your phone.

Another reason is that you are recording the video in high resolutions. You should try to reduce the video resolution while recording.

This helps reduce the excess data that is needed to be processed by your camera which in turn reduces the grainy video effect. To do reduce the resolution of your camera, follow the steps below:

  1. Open the settings app on your iPhone.
