Image description,tag,.. not preserving while converting to video

I gave image description like below

imwrite(uint16(testImage),outputFileName,'Description','This is very important');

It worked and i got the description as expected but, when I take several images like this and convert it into video with below code

outputVideo = VideoWriter(fullfile('EncryptedVideo','Video.mp4'));
outputVideo.FrameRate = app.videoFrameRate;%Setting the frame rate   
open(outputVideo)
encryptedImageFolder='FinalImages'
encryptedImagePath=dir([encryptedImageFolder '/*.tiff']);
numberOfEncryptedImages=size(encryptedImagePath,1);
%Looping through all images and adding to video
for i = 1:numberOfEncryptedImages
  img = imread(['FinalImages\finalImage' num2str(i) '.tiff']);
  writeVideo(outputVideo,uint8(img))
end
close(outputVideo)

I am losing the description, tags, comment etc after extracting it back.

Do anyone know how to preserve the image details while converting to video?
