I'm a student of the Art Academy of Rotterdam and my max teacher run away to Iceland ore something. This is the reason to ask some help over here :-)
Last year I build a audiovisual playtoy: http://www.beatnologic.com/site/content.php?id=250
Some video's keyed over a background image.
Now I want to do the same but then with openGl videoplanes. Everything work fine exept the alpha stuff.
I don't know what I'n doing wrong. Is it posible to do something linke this, http://www.beatnologic.com/site/content.php?id=283
but then with alpha video's?
Does anybody, maybe has a example patch and a demo mov with alpha channel?
