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
