How To Display Video From CV2 in Tkinter (Python 3)

After recently having a go at using cv2 in python, I wanted to combine cv2 and Tkinter to make an application where the video from my webcam would display in a Tkinter window, sadly after searching the internet for a while on how to do this, I found no good solutions so decided to have a go myself, and this is a post showing you how to do exactly that.

The code is below with comments:

#Created by Flynn's Forge 2020, from
import cv2
from tkinter import *
from PIL import Image, ImageTk
#Creating Tkinter Window and Label
root = Tk()
video = Label(root)
#Getting video from webcam
vid = cv2.VideoCapture(0)
#Loop which display video on the label
    ret, frame = #Reads the video
    #Converting the video for Tkinter
    cv2image = cv2.cvtColor(frame, cv2.COLOR_BGR2RGBA)
    img = Image.fromarray(cv2image)
    imgtk = ImageTk.PhotoImage(image=img)
    #Setting the image on the label
    root.update() #Updates the Tkinter window

So how does this work? Well we simply grab each frame from the video capture and convert it into something Tkinter will work with and then update the Tkinter window every new frame.
