Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,so we spent all this time saying, okay, \NI could have a blank PImage
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,and i could figure out some \Ninteresting algorithmic way

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,or, I could have an image thats coming \Nfrom a file, like frog.jpg

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,we could have a camera, \Nthis is my weird drawing of a camera
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,and what if i could pull in a live image\Nfrom a camera into my Processing sketch
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,What could I do with that? what if I had a\Nyou know, a movie file?
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,could I pull in that movie and play back \Nthat movie in my Processing sketch?

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,How do we make this happen? So, let's \Nfirst just take the basic transition from
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,flat image file to camera and the way \Nthat we're going to do this
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,is with Processing's Capture object\NSo, the Capture object, is part of,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Processing's video package\NNow, I just realized,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,there's kinda a crucial component to this,\Nif you are using, and again, this part of

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,and i pull this up, you won't, by default,\Nhave the video library, so I'm going to
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,search under Processing, and this is what \Nyou're looking for, you wanna find
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,in this contributions manager, 'Video' \Nlibrary by The Processing Foundation
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,so, in order to run any of these examples,\Nor, to work with live video

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,of Processing here, so, this is-, \Nwe're going to test this out
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,you just wanna hit this 'install' button \Nand, uh, while it's downloading
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,and should be ready to go, and now,\Nwe're going to have this library!
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,yeah! and then it'll say 'remove', so, if\Nyou don't have the video library,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,make sure you get it (button click)\Nokay, back over here!
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Once you have the video library, you \Nnow have access to the Capture object

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,back in Processing, so
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,here's the thing, the thing that's \Nthe most wonderful about this
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,is that, both of these things are PImage's\Nessentially, all the functionality; image,

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,and practiced, and did with PImage, you \Ncould do exactly the same functionality
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,with Capture and Movie
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,the only thing that's different, is when\Nyou load a PImage, like frog.jpg,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,those pixels are never gonna change, \Nunless you change them, right?
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,that file, that image is a \Nflat, static image
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,those pixels are the pixels
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,you could do all the same operations! but\Nwith a Capture object or a Movie object,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,those pixels might be changing according \Nto some schedule, of course,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,we have total control over that schedule, \Nwe could say, give me fresh pixels from

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,so this is an added piece of the puzzle, \Nthat we'll be able to work with
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,as we start using these classes, so, let's\Nsort of, uh, let's look and see how this
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,would work, there's a couple little\Nnuances here, so, i'm back over here,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,and i'm in a sketch, so, this is just a, \Nkind of a simple processing sketch
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,that I think we did at some point in an \Nearlier video, I'm loading an image,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,I'm drawing it on the screen, \NI'm using a couple things;
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,#1 - you can see I can dynamically resize\Nthe image as i draw it, using the mouse,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,or I could also tint it, meaning, \Nchange its color, so,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,what I want to emphasize in this-, \Njust first part of this video,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,is let's make this the Capture object from\Nthe camera, I have a laptop in front of me
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,its not all magic, let's get that image\Nfrom that camera, and let's see that there
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,and do all the same stuff for it, \Nso, instead-, the first step is,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,instead of a PImage, I wanna say, \NCapture and I'm gonna say video
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,now notice, as soon as I do that, I get \Nan error message, it says, um,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,if I look at the errors, you can see, \Nthe class Capture does not exist,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,now this needs a little bit of work here,\Nbut it's actually giving me a suggestion
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,which is nice, this is-, Capture and Movie\Nare both part of that Processing video

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,I'm just gonna-, Processing will \Nadd this for you automatically,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,in a bunch of different ways, \Nbut I'm just gonna do it manually,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,so I just need to have an import statement\Nat the top; import processing.video.*;
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,now I have my Capture object, now,\N
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,you might think, you would say \Nsomething like: "I said loadImage(),
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,so, loadCapture (should work) or \Nsomething? createCapture, connectVideo,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,startVideo", um, the way that \Nthis works however, is,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,there is no function like that, we need to\Nuse the tools and syntax of
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,object oriented programming, \Nso lets come back over here
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,and if I have a video object, the syntax \Nis to say, I wanna make a new...
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,Capture object, and I need to figure out,\Nwhat goes in there, so,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,what might be some parameters \Nthat you need
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,when you're about to connect to \Nthe live camera?

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,so, some parameters we're going to \Nput in there as the width and the height

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,another piece of information that we \Nmight put over here, is... frame rate

Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,so, a lot of this really depends \Non what you've got,
Dialogue: 0,9:59:59.99,9:59:59.99,Default,,0000,0000,0000,,and I'm going to show \Nyou a way to figure out
