How can I display videos without movie()?

Hello, first of all I am sorry for my English.

I am making a project on GUI. It is video denoising. First video is original video, second one is noised video, third one is denoised video. When I use this code, filtered videos get longer. It is like a slow motion video. Let's say that original video is 7 seconds. Noisy video is more than that. And also filtered video is longer than original video.

I can solve it using movie(). But I want to compare videos. I want to see all of them in the screen. I don't want to use figure to create a new window.

But movie() always waits for the playing to finish.

Here is my gui.fig

% Here is my original video
v=VideoReader(filename);
H=v.Height;
W=v.Width;
s1=struct('cdata', zeros(H,W,3, 'uint8'), 'colormap', []);  
k=1;

axes1=handles.axes1;
while hasFrame(v)
    s1(k).cdata=readFrame(v);
    image(s1(k).cdata,'Parent',axes1);
    pause(1/v.FrameRate);
    k=k+1;
end

% Here is my noisy video
value= get(hObject,'Value'); 
s2=struct('cdata', zeros(H,W,3, 'uint8'), 'colormap', []);

axes2=handles.axes2;
if value==2
    for i=1:k-1
        s2(i).cdata=tuzbiberGurultusu(s1(i).cdata);
        image(s2(i).cdata,'Parent',axes2);
        pause(1/v.FrameRate);
    end    
end

% Here is my filtered video
value= get(hObject,'Value'); 
s3=struct('cdata', zeros(H,W,3, 'uint8'), 'colormap', []);

axes3=handles.axes3;
if value==2
    for i=1:k-1
        h=fspecial('average',3);
        s3(i).cdata=imfilter(s2(i).cdata,h);
        image(s3(i).cdata,'Parent',axes3);
        pause(1/v.FrameRate);
    end
end

If you want to have the OS play the movie, try calling winopen(filename) (Windows only), or system().

[Enes Alkan]

So I should write video to file and then I should call winopen() ?

You can do that if you want. Another way wuld be to make a new movie where you stitch together the frames from the two movies side by side. That way they'll always by in sync.
