different size of files

Hi every one

I want to make copy for AVI file by using the following code

close all clear all [filename pathname] = uigetfile('*.avi','File Selector'); vid = strcat(pathname, filename); obj = mmreader(vid); vid = read(obj); frames = obj.NumberOfFrames; new10=avifile('outputvideo\one_colour_video.avi','compression','None'); for x = 1 : frames

    a=vid(:,:,:,x);
    a(:,:,1)=0;
    a(:,:,2)=0;
    blocks{x}=a;
end
for f=1:frames
    new10=addframe(new10,blocks{f}); % the result is noisy movie
end
new10=close(new10); 
msgbox('end of operation','Message','warn');

unfortunatelly, the size of the output file is different from the input file

so, how to make them in the same size,

regards

Majid
