Hi,

I understand that you are trying to extract frames from a video at 10 seconds, 20 seconds, 30 seconds, 40 seconds, 50 seconds. Following is the code to perform the operation : -

v = VideoReader('exampleVideo.mp4'); 
time = [10, 20, 30, 40, 50]; 
for i=1:numel(time) 
    if time(i)<v.Duration 
        v.CurrentTime = time(i); 
        frame = readFrame(v); 
        figure; imshow(frame); %Perform processing on the frame here 
    end 
end  

For more information, refer to VideoReader.
