vidObj = VideoReader('C:\Users\Public\Videos\Sample Videos\Wildlife.wmv'); % video file
%% Read the video frame by frame
numFrames = 0;
iwant = cell([],1) ;
while hasFrame(vidObj)
F = readFrame(vidObj);
numFrames = numFrames + 1;
imagesc(F)
drawnow
iwant{numFrames} = F ;
end
%% Write to video
v = VideoWriter('myFile','Archival');
v.VideoCompressionMethod
open(v)
for i = 1:numFrames
writeVideo(v,rgb2gray(iwant{i}))
end
close(v)

Read about videowriter. You may use some thing like below:
v = VideoWriter('newfile.avi','Motion JPEG AVI');
