I used VideoReader to load the video from my down loads and read() to read each frame. How do I save the image and then save that image to the cell of a preallocated cell array?
v=VideoReader(movieFile);
numFrames=v.NumberofFrames;
c=cell(1,numFrames);
for a=1:numFrames
frame=read(v,a);
imwrite(frame,['Image' int2str(a), '.jpg'])
c(a)=frame;
end

vidObj = VideoReader('C:\Users\Public\Videos\Sample Videos\Wildlife.wmv');
numFrames = 0;
iwant = cell([],1) ;
while hasFrame(vidObj)
F = readFrame(vidObj);
numFrames = numFrames + 1;
iwant{numFrames} = F ;
imagesc(F)
drawnow
end
numFrames
