If Quartz Composer is crashing you likely have something like QCRehab installed somewhere. I would suggest removing it. Once you get Quartz to open, you can manually specify the size of the render in image patch to the size of the incoming image (via the Image Dimensions patch), or set the pixels width/height to 0 so it will size to the *destination* context (usually the full window). I would suggest using the input image size, as outputting to the context/destination size is kind of unnecessary in my opinion.
