Creating a new file to save data to

I'm trying to save a bunch of JPG images of data to a seperate file than where the mat program is located. Currently I have the below to name each image of data saved, but I'm not sure how to save these images to a new file.

obj = VideoReader(Image);
vid = read(obj);
frames = obj.NumberOfFrames;
timeStamp = getTimeStamp;
for x=1:frames
    imwrite(vid(:,:,:,x),strcat('frame-',num2str(x),'_',timeStamp,'.JPG'));
end

Any suggestions for how to save each image to a new file?

Is getTimeStamp from https://www.mathworks.com/matlabcentral/fileexchange/47075-cmacminn-gettimestamp ? But even that expects to be passed a file name.

It's a different function I created. It does not require another function to be passed into it. I made it work though, and can now successfully save to a different folder and file. Thank you
