hello... i would be interested in this too if anyone has something. i actually was just trying some stuff out with a green screen but did not get very far.
although i did not play around for long i did have trouble getting the [pix_chroma_key] to work well (or do anything at all for that matter). i just did something like: [gemhead 1] | [pix_video] | [pix_alpha] and [gemhead] | [pix_film] ...but im sure there is someone that knows something better optimized for green/blue screen work. --- On Tue, 2/3/09, Martin Schied <crini...@gmx.net> wrote: > From: Martin Schied <crini...@gmx.net> > Subject: Re: [PD] video bluescreen > To: "Garrett Lynch" <li...@asquare.org> > Cc: pd-list@iem.at > Date: Tuesday, February 3, 2009, 2:41 PM > Hi, > > Garrett Lynch wrote: > > I'm trying to put together a video bluescreen and > I'm just not finding > > the right object I think. pix_multiply sort of does > what I want by > > dropping out white in a video and replacing it with > another video but > > how do I get this working with a defined colour (i.e. > not necessarily > > white but the blue or green normally used in studios). > There seem a > > few objects that deal with different ways of mixing > > images/videos pix_mask, pix_mix, pix_composite etc. > Which is the > > right one to use?
