Switching from a cinematic cycle to the player camera

Hi, I'm new in Unity and I'm trying to learn the coding on my own

I'm going for a simple exercise were I combine different codes from other tutorial into a new project so I can see how to script into different contexts

I'm trying now to start the game with a cinematic sequence for then switching to a first person controller, but I can't find an example on how to change the script

 public static bool gameStarted = false;

 [SerializeField]
 private List<GameObject> cameras;
 [SerializeField]
 private Image screenFader;

 private int activeCamera = 1;
 private int nextCamera;

 private float timer;

 [SerializeField]
 private float timerDelay = 8f;
 [SerializeField]
 private float fadeSpeed = 8f;

 // Use this for initialization
 void Start () {

     cameras [activeCamera].SetActive (true);
     nextCamera = activeCamera;

 }
 
 // Update is called once per frame
 void Update () {

     // If the game has started...
     if (gameStarted == true) {

         // ...switch to the player camera
         SwitchCamera(0);

     } else {

         // otherwise, cycle through the other cameras.
         CycleCameras();

     }
 
 }


 private void SwitchCamera(int cameraIndex) {

     if (cameraIndex != activeCamera) {

         // If the screen fade is less then (almost) full black...
         if (screenFader.color.a <= 0.998f) {

             // ...then continue lerping the screen fader towards black.
             screenFader.color = Color.Lerp (screenFader.color, Color.black, fadeSpeed * Time.deltaTime);

         } else {

             // ...set the screen fader to black.
             screenFader.color = Color.black;

             // Change the active camera
             cameras [activeCamera].SetActive (false);
             activeCamera = cameraIndex;
             cameras [activeCamera].SetActive (true);

         }

     } else {

         // If the screen fader is not close to completely clear...
         if (screenFader.color.a <= 0.002f) {

             // ...then continue lerping the screen fader towards clear
             screenFader.color = Color.Lerp (screenFader.color, Color.clear, fadeSpeed * Time.deltaTime);

         } else {

             // ..set the screen fader to clear.
             screenFader.color = Color.clear;

         }

     }

 }

 private void CycleCameras() {

     // Increment a timer to count up to restarting
     timer = timer + Time.deltaTime;

     // If the timer reaches the restart delay...
         if (timer >= timerDelay) {

             // Then reset the timer
             timer = 0f;

             // Choose the next camera
             nextCamera++;

             // If the next camera is greater then the highest index in the camera list...
             if (nextCamera > cameras.Count - 1) {

                 // ...then reset to the first cinematic camera.
                 nextCamera = 1;

         }

     }

             // Switch to the next camera.
             SwitchCamera(nextCamera);

 }

Inserting the player camera in the script list seems to work under different conditions but then the cycle doesn't stop when I start the game

A little advice would be appreciated
