Video not playing smoothly

I have this code converting from images to a video. But the problem is, the output video is not playing smoothly. Can anyone figure out the problem please?

baby = VideoReader('baby.avi'); 

imageNames = dir(fullfile('D:\code_video_watermarking\watermarkframes\','*.jpg')); 

imageNames = {imageNames.name}'; 

outputVideo = VideoWriter(fullfile('D:\code_video_watermarking\','watermarked_video.avi')); 

outputVideo.FrameRate = baby.FrameRate; 

open(outputVideo); 

for i = 1:length(imageNames) 

      img = imread(fullfile('D:\code_video_watermarking\watermarkframes',imageNames{i})); 

      img = ycbcr2rgb(img); 

      writeVideo(outputVideo,img); 

end 

close(outputVideo); 

shuttleavi = VideoReader(fullfile('D:\code_video_watermarking\','watermarked_video.avi')); 

ii=1; 

while hasFrame(shuttleavi) 

      mov(ii) = im2frame(readFrame(shuttleavi)); 

      ii = ii+1; 

end 

f = figure; 

f.Position = [150 150 shuttleavi.Width shuttleavi.Height]; 

ax = gca; 

ax.Units = 'pixels'; 

ax.Position = [0 0 shuttleavi.Width shuttleavi.Height]; 

image(mov(1).cdata,'Parent',ax); 

axis off 

movie(mov,1,shuttleavi.FrameRate);

You might want to experiment with VideoPlayer, which should be more efficient than movie()

However, movie() can use an existing figure but VideoPlayer needs its own figure.

So how to use the videoplayer?

still the output video is not playing properly
