Just for fun I added four seperate preview panes for my Sequence Grabber code – each pane has its own CoreImage filter attached. All previews can be flipped horizontally as well (I just apply an affine transformation to the image before handing it off to the four preview filters). I also fixed a couple of little bugs. I am not updating the demo archive so to see the changes you’ll need to download and compile the code.
