HI Vilson, That video you posted seems like mixing a little bit of audio signal into the video and maybe viceversa... (analog glitch). Looks also like an analog video mixer w circuit bending.. http://vimeo.com/8913301 I did found a nice way of making glitches in pd http://vimeo.com/6932986 (minute 1) this is done by having two copies of the same pix and applying a very subtle but very fast 3d transformation [rotateXYZ] to one of them, for this task, I use the audio input.. If you are interested, I can post an example.. Hi András. thanks for the tricks!. but already pd runs quite fast.. I will do like that next time I install.
