There are two ways to arrive at the correct settings:

Through the camera itself

Using the Gopro app

The first step in any time lapse is to make sure your camera is secure and is not susceptible to camera shake which can ruin an otherwise perfect time lapse. This can be done in a number of ways:

Tripod

Supplied Gopro mounts

DIY 'egg timer' mount

Motorised slider

Any other DIY mount (as long as it's secure)

Any of these will ensure the best possible result when time lapsing and are essential to your success. Once the Gopro is securely mounted it is time to setup the camera to be ready for taking the time lapse.

Method #1 - In camera

This method involves using the buttons on the Gopro itself in order to get to and change the appropriate settings. The following video illustrates how to navigate to the menus to achieve this.
