I am trying to store a string while writing images to video using below code

           data='This necessary string i need after converting to video'
           outputVideo = VideoWriter('TestVideo.avi','Uncompressed AVI');%image format and compression
           outputVideo.FrameRate = app.videoFrameRate;%Setting the frame rate  
           open(outputVideo)
           TestImageFolder='FinalImages';
           TestImagePath=dir([TestImageFolder '/*.tiff']);
           numberOfTestImages=size(TestImagePath,1);
           %Looping through all images and adding to video
           for i = 1:numberOfTestImages
            img = imread(['FinalImages\finalImage' num2str(i) '.tiff']);
            writeVideo(outputVideo,uint8(img))
           end
           close(outputVideo)
