Im building a patch similar to the one in jitter tutorial 14. I have enclosed an example at the bottom of the page. click on "impportmoviesunset,jpg", click the metro, click on preset 9, and make sure the toggle on "erase previous image" is marked off. notice how the background is black? say i wanted to record a performance of this, then in adobe premiere pro, or some other commercial software, i put a picture of a flower in the background, the background will still be black. Is there a way to make the background clear, so you can see the picture of the flower in the background?
