So, let's continue working on this further by covering the concepts of basic effects in both E and nuke. Now, for those who don't know, and those who perhaps know we all know or eventually will know the first step into Visual Effects designer rotoscoping, or green screen, both of which I cover in my other classes, but for now for this lesson, I will specifically go through three of the most basic effects and notes you need to know as a total newbie, and beginner in the software familiarization cause roto. Much and key light. I will also cover which one of these tie in with After Effects so no worries for those transitioning from A to E. Alright, assuming that you would want to create a crop and mask out this apple to put on his face to replicate this painting right here. in After Effects. This would simply be the To where I can simply click on this icon or hit G, and then create a mask, I'm just going to do one very roughly, whilst having that layer selected and closing it after to create a Bezier.

If you have not already noticed, you simply click, press, hold and drag, and there you go, you have a smooth curve point, if not, it will be pretty sharp kind of like this. In nuke, this would be an actual note. So instead of a pen tool, and I call it a new electric be an actual node, just like everything else, where you basically create your mask. In fact, it is such a basic node and there's even a shortcut key to it. So if you hit the O key, you can create a roto node. Now you might be wondering why not the R key because the R key is already occupied for something else.

So all you need to do basically is to not even pipe this in so I'm just going to actually delete these numbers here, double click on my roto node, make sure that it is the first thing you see in your properties tab. And then with this selected double click, I'm basically going to draw my mask inside the viewer with the layer that I'm viewing in view. So I'm just going to make sure I'm looking at the correct layer, click on my apple, hit one to bring up the viewer and double click on roto. Again, minimize button click to center all my current available notes. And then basically mixture that I have this little icon selected, that basically means I want to create a curve and the Bezier shortcut keys V and then basically create your mouse Now again, in order to create the Bezier curve and bezzie a meaning the smoothed edge curve, you have to again click press hold and drag holding down your left mouse button whilst you create your points kind of like the same as after effects.

Now I'm just doing this very quickly. Just going to create a very quick one, you can do this read nicely later, and then click and press and hold at the original point to close. Alright, so now now that that's done in After Effects for those who are familiar with a UI, you will know that in order to basically have this layered on top of the other, all you need to do is to have the background layer underneath it. But what about nuke now in nuke, as you might already guess, just like everything else, you would actually have to use another basic node in order to view your work on top of another. And here's where we bring in the Merge node. And if you click Assign and away from your router, making sure that this is not highlighted orange hit m to bring out a Merge node.

And what I'm going to do is basically type in a which will represent my foreground to the apple. And if I zoom in, you can see this little arrow right here is a hidden arrow showing mask. So again, these input pipes will basically describe what kind of input you want to put into your nodes. So I'm just going to pipe in To the mask, and then making sure that my B pipe goes to the david node right here. Now in order to view this, as you already might have been familiar, click on the node one. And you can see that it is right now on top of David.

Now there might be a little bit of artifacts here, which we'll fix very shortly. But very quickly, you can see that the layers are overlaid on one another based on this Merge node right here, there is no Merge node and After Effects, you can see why nuke has its own Merge node. Basically, it allows you to have more customization in terms of how you want to lay your elements together, or actually, in this case, composite two elements together. And of course, the most No, if you double click has its own Blend Modes as well and I can actually go through these right here over operations. You can see I can actually have different kinds of Blend Modes so it can highlight basically affecting the A input to be what however, is going to be blended with my image. Now of course in After Effects, these actually found right here, under move You can see the same thing.

Multiply overlay difference. I can also do that here in nuke difference. See, same thing. Now of course in After Effects, nothing speaks visual effects, then green screen and chroma keying like key lights. So actually a little bit of interesting tidbit key lights was actually created by the foundry who created As you already know, nuke so let's see how it looks like in both After Effects and nuke. So I'm just gonna actually very quickly search for key light in my effects and presets.

I'm just going to set this back to normal, blinking lights all over the apple to turn off the favorite layer. can see I just keyed a random color. And in nuke, I'll actually just go right here click that make sure that my original Apple selected, hit Tab search for key light enter and automatically pipes in to the correct input pipe for me. In this case, it is a sauce input to one Then click on this little icon right here to select a color was my mother's interviewer, press and hold CTRL to select a color and let go to see the same thing. You can see how similar they are, it's just that they are laid out a little bit differently. See screen color, screen color screen gain, everything looks the same.

Now again, a very quick tip for those who are completely new to visual effects itself. The keying process, it doesn't necessarily have to be green, but it can be any color, which kind of works the same in both After Effects and nuke as well. So for example, if I want to change this to the green, I can keep it green, just like this one and you want to change this or just press and hold CTRL and then select new point, you can see that if I zoom in that little red dot basically is telling me which color I want to select. Same outcome, same results in a way. Okay, so I'll let you guys finish off this in the assignment later but for now, let's get things cleaned up and move on to organizing our seen in nuke, still confused, post your questions on the q&a board and I'd be happy to jump right in and help
