Hello,
It appears you are working on a project to create a dataset by capturing and storing each frame of a video.
To achieve this in MATLAB, you can use the VideoReader class to read the video and the readFrame method to extract individual frames. The imwrite function can then be used to save each frame as an image file.
MATLAB's Computer Vision Toolbox can be particularly helpful for this task. If you are new to this toolbox, I recommend taking the Computer Vision Onramp course provided by MathWorks. This course will help you quickly get up to speed.

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