Hi all,

Does anyone know how to grab pixels’ colors from a live video input and have those color feed into a generating graphic?

I have a webcam hanging from the ceiling, and it’s pointing down to see the people passing by. I want to grab the color values of each pixels from what the webcam is seeing and use those colors in a graphic that is playing on a screen.
So, for example, some people wearing red, orange, blue walk pass by the webcam, the graphic would generate red, orange, blue lines.

Sorry if this might be confusing, I’m still a beginner user and don’t know all right terms yet.
Thank you!

Hi Dushin,
There are a few tutorials in Jitter that go into detail about analyzing color information in video. You should review those first if you’re just beginning.
What you’re doing could also be achieved with a slitscan effect. Search through your Jitter matrix example patches on your computer to find the slitscan sample patches that come with Max. Once you have a patch started post it back here and we can give you more guidance.
