How can I convert movie to 3 channels frames

How can I convert movie.avi into 3 channels frames (red, green, & blue) and store the red channel images in folder1 and green channel images in folder2 and blue channel images in folder3

1) U should convert the movie into images that u can refer http://in.mathworks.com/help/matlab/examples/convert-between-image-sequences-and-video.html Then u can covert the image files into red blue and green images by accessing the index i'm assuming name of the variable that holds image file info is "RGB".

R=RGB(:,:,1);
G=RGB(:,:,2);
B=RGB(:,:,3);

Then u can refer the following link to create a new folder in matlab http://in.mathworks.com/help/matlab/ref/mkdir.html then u can use the following command to write the image file

imwrite(image,'<foldr path>','jpg')
