If you have a RGB frame F os size m*n*3...
R = F(:,:,1) ;
G = F(:,:,2) ;
B = F(:,:,3) ;

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
I = rgb2hsv(iwant{i}) ;
% Get h,s,v
h = I(:,:,1) ;
s = I(:,:,2) ;
v = I(:,:,3) ;
writeVideo(v,I)
end
close(v)
