Alpha Channel on quicktime movies
Mar 19th, 2008, 7:20pm  
Hi, Is there a way to open quicktime movies that have an alpha channel set up for tranparency reasons ?

I've done this before with Max/MSP/Jitter, but I can't get it working in Processing.

I've already tried using two separated movies, one with the colors and another with a Gray scale Image that I used as an alpha mask, but the result is realy poor.

Is there another way of doing that ?

Can anyone help me ?

Thanks.

I was asking the same question a week ago, The way to do it is not what you'd expect. Import a Quicktime file with an alpha channel and RGB channels. Then display that file and also use the same file as the mask.

eg,

   image(myMovie, 0, 0);
   myMovie.mask(myMovie);

hope that helps.
