vid = videoinput('winvideo', 1, 'YUY2_640x480'); set(vid, 'FramesPerTrigger', Inf); set(vid, 'ReturnedColorspace', 'rgb') vid.FrameGrabInterval =5; start(vid) while(vid.FramesAcquired<=50) img_orig = getsnapshot(vid);
height = size(img_orig,1); width = size(img_orig,2);
%Initialize the output images out = img_orig; bin = zeros(height,width);
%Convert the image from RGB to YCbCr img_ycbcr = rgb2ycbcr(img_orig); Cb = img_ycbcr(:,:,2); Cr = img_ycbcr(:,:,3);
%Detect Skin [r,c,v] = find(Cb>=77 & Cb<=127 & Cr>=133 & Cr<=173); numind = size(r,1);
%Mark Skin Pixels for i=1:numind out(r(i),c(i),:) = [0 0 255]; bin(r(i),c(i)) = 1; end figure; imshow(bin); end stop(vid); flushdata(vid); clear all end

I don't understand the question. Can you be more specific? "I want to take a video" implies that you want to extract a new video from the existing video. However you you said that "it creates lots of frames" which implies you want few or maybe only 1 frame. So do you want to create a new video, or just save one frame from the video into a new disk file?

Usually you accept the answer of the person who helped you, not your own "thanks" comment.

The second half of the attached demo shows how you can build a video from a series of frames or files on disk.

That would be about half way down where you see the comments:
% Ask user if they want to read the individual frames from the disk,
% that they just wrote out, back into a movie and display it.
