How to store a string in video description or somewhere so that i can retrieve it?

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)

I really want to store the data in the video or in the description or somewhere so that i can read it again, does anyone know a method for this?

Hi Ashwin,

You can create a MATLAB object to store your video and description. You can achieve this by defining a simple class as shown below:

classdef VideoWithDescription
    properties
        video
        description
    end
    
    methods
        function obj = VideoWithDescription(video, description)
            obj.video = video;
            obj.description = description;
        end
    end
end

The solution is specific to MATLAB and won't be directly applicable if you need to process or share this data outside of MATLAB.

If you want to share the data outside of MATLAB, you can store your string in a separate text file with the same base name as your video file. For example, TestVideo.avi can store the video and TestVideo.txt can store the video description. This is a simple option if you don't managing separate files.

I hope this helps.
