Jittering effect when moving character and camera

Question

Hey!
I want to make a game and I wrote some code that really suits my needs but I'm having a problem. When I'm moving the character and the camera at the same time I get this really weird jitter effect. When I'm moving only the camera or the character I don't get this. Here is my code for the camera:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class MouseLook : MonoBehaviour
 {
 
     public float speedH = 2.0f;
     public float speedV = 2.0f;
 
     private float yaw = 0.0f;
     private float pitch = 0.0f;
 
     public Transform tran;
     //This tran is the character transform
 
 
     // Use this for initialization
     void Start()
     {
 
     }
 
     // Update is called once per frame
     void Update()
     {
 
         yaw += speedH * Input.GetAxis("Mouse X");
         pitch -= speedV * Input.GetAxis("Mouse Y");
 
         transform.eulerAngles = new Vector3(pitch, yaw, 0.0f);
         tran.rotation = Quaternion.Euler(0, yaw, 0);
 
     }
 }

And this is the character code:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class PlayerMove : MonoBehaviour {
 
         public float speed;
 
         private Rigidbody rb;
         private Transform tr;
 
         void Start()
         {
             rb = GetComponent<Rigidbody>();
             tr = GetComponent<Transform>();
         }
 
         void FixedUpdate()
         {
             float moveHorizontal = Input.GetAxis("Horizontal");
             float moveVertical = Input.GetAxis("Vertical");
 
         rb.MovePosition(tr.position + (tr.right * moveHorizontal * (speed * 0.01f) + (tr.forward * moveVertical * (speed * 0.01f))));
 
     }
 }

So I tried a lot of stuff but nothing works. How do I make this work without jittering? EDIT: Here is the gif of the jittering. Look at the cube. You don't see it when the gif is small. Just zoom in the page. http://imgur.com/6yChVjI

I found a solution. Instead of rotating the camera on the y axis and then rotating the character, I rotated the character directly on the y axis and camera on the x axis. Of course the camera must be a child of the character.

for what i see i'm pretty sure that u r setting the rotation, location of the camera directly on it! u should use some sort of lerp to smooth the movement of the camera to where player is, or to the specific rotation that u desire and this will create a smooth transition and remove the jittering.

here some link that can help u!

I lerped like you said but it's still jittering. Here's my look script now:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class MouseLook : MonoBehaviour
 {
 
     public float speedH = 2.0f;
     public float speedV = 2.0f;
 
     private float yaw = 0.0f;
     private float pitch = 0.0f;
 
     public Transform tran;
 
     float lerpTime = 1f;
     float currentLerpTime;
     //This tran is the character transform
 
 
     // Use this for initialization
     void Start()
     {
 
     }
 
     // Update is called once per frame
     void Update()
     {
 
         yaw += speedH * Input.GetAxis("Mouse X");
         pitch -= speedV * Input.GetAxis("Mouse Y");
 
 
 
 
         //reset when we press spacebar
         if (Input.GetKeyDown(KeyCode.Space))
         {
             currentLerpTime = 0f;
         }
 
         //increment timer once per frame
         currentLerpTime += Time.deltaTime;
         if (currentLerpTime > lerpTime)
         {
             currentLerpTime = lerpTime;
         }
 
         //lerp!
         float perc = currentLerpTime / lerpTime;
 
 
 
 
         transform.eulerAngles = Vector3.Lerp(transform.eulerAngles, new Vector3(pitch, yaw, 0.0f), perc);
         tran.eulerAngles = Vector3.Lerp(tran.eulerAngles, new Vector3(tran.rotation.x , yaw, tran.rotation.z), perc);
 
 
     }
 }

Make the camera movement on LateUpdate, this also helps to remove this kinds os problems.
