In order to provide a means of cropping and zooming video I wish to be able to draw a moveable rectangle and cross-hair over the video image. I can use VMR to mix the graphics onto the video but because it must work with any video, sometimes the video is resized to fit into a fixed sized window. This causes the graphics to be resized as well, but worse still, the resizing algorithm (point or bilinear) causes single pixel width lines to disappear altogether!. What I need is a means to display nice sharp single pixel width graphics over the video. Has anyone any suggestions Thanks in advance.

It dawned on me that if I was to resize the video before it reached the VMR this effect would not occur. Is there a standard way of doing this
