Why is PIL's Image.fromarray() distorting my image color? [duplicate]

Question

I am generating thumbnails for mp4 videos using the following code:

import cv2 as cv
from PIL import Image 

vidcap = cv.VideoCapture(videoPath)
vidcap.set(cv.CAP_PROP_POS_MSEC, millisecond)

#Turn video frame into numpy ndarray
success, image = vidcap.read()
cv.imwrite('fromImage.jpg', image)   #line to be replaced

The thumbnail generated from a high budget, professionally shot video looks like this: Unfortunately in my application context, I will not be able to write the image frame directly to a file. Instead I must convert the image array generated by cv into a PIL image and then go from there. It looks something like this:

# Turn numpy ndarray int PIL image
img = Image.fromarray(image)
img.save('fromArray.jpg')    #Saving it for stackoverflow

But the outputted thumbnail from the same mp4 video is completely distorted as it seems to have swapped red and blue and looks like this: Who or what is the culprit in this image distortion?

imageRGB = cv.cvtColor(image, cv.COLOR_BGR2RGB)

img = Image.fromarray(imageRGB)

img.save('fromArray.jpg')
