    writerObj.FrameRate = 26.1882 ;
    %frame rate aku dapet dari data/waktu
    open(writerObj);
    
    %bawah yang proses bikin videonya
    for i = 1:length(F)
        frame = F(i);
        writeVideo(writerObj, frame);
    end
    
    close(writerObj);
end
close all;

But I have problem with the frame rate. How i fix this?

Error using VideoWriter/writeVideo (line 368)
Frame must be 560 by 420
Error in MPCTrainPFAnimation1 (line 218)
        writeVideo(writerObj, frame);
