Hello, so I am creating a GUI where I want to have a preview of a video, but without it opening up in another window. Is that possible? preview() opens another window, and I tried to experiment with imshow, but I'm not sure on how to really do this. My computer is attached to a camera device and I already have that setup. Thank you!

You can use the command:
preview(vid, hImage);
where hImage is the handle to the image object in which the data is to be displayed.
How are you creating your UI? Are you using App Designer?

I was able to get it to display into the UIAxes; however, it only records a small, "zoomed in" section of the vidoe input and only fits a small part of the UIAxes/doesn't extend to the edges. How to fix this?
