Hello,
I’m an absolute beginner with Pure Data and am trying to create a patch that links my webcam to a video. When the webcam detects movement the video should slow down; the more movement there is, the slower the video should play. I hope someone reading this could give me some advice as I find it difficult to get started. I found a way to display the webcam but have no idea how to link it to a video.
Thanks

From there you can either take any of the numerical position numbers and feed it into [trigger bang] which will output a bang whenever there is a change (i.e. movement) Then feed the bang into your system that slows down video. Or instead of [trigger bang] you could create an algorithm that detects greatness of number change, and feed that into your slow video patch... i.e. the greater the motion the slower the video. e.t.c.
