In Premiere Pro CS4 Beyond the Basics, Adobe Certified Instructor Chad Perkins explains how to take video editing from simple nuts and bolts to an art form. He shares tips for shooting video in the field to get the most from a subject and get the best footage for a project. He demonstrates how to build a project through the careful use of cutaways, pacing, and suggestive edits. He covers special effects, color correction, and keying and compositing, integrating all these concepts as he builds a music video project from scratch. Exercise files are included with this course.
In this chapter, we're going to dig a little bit deeper into what you can do with effects. We're going to start out by looking at how to create censored parts of video. This is used very frequently in video, especially non-fiction video, but when some little prankster comes along and does something obscene that needs to be edited out, maybe a particular hand gesture, or maybe they say something foul that needs to be edited out, or like you don't even want to see their lips moving and say those words, or maybe you want to obscure somebody's personality if you're interviewing them.
You don't have the rights to show their face on camera. So that's what we're going to do here. We're going to edit out this guy's faces if it were forbidden to be seen. So what we're going to do is we're going to start out by using the Eight-Point Garbage Matte. We'll look a little bit more in detail at Garbage Mattes a little bit later on this training series. But I'm going to apply this effect, and actually I'm not going to apply it to the original. I'm going to drag a copy of the original on a track on top of the original. So yes, that might sound confusing at first, but what we are looking at is two different tracks with the same footage.
So I'm going to apply the Eight-Point Garbage Matte to the top layer here. If it helps, you can take the visibility off of the video track 2. As you probably notice, we don't have anything on Video 1 or Audio Track 1, so we can right-click and select Delete Tracks. Then we could select Delete Video Tracks and Delete Audio Tracks and make sure these dropdowns are set to All Empty Tracks, and click OK. That cleans up our Timeline panel quite nicely. So I'm going to apply the Eight-Point Garbage Matte or make sure that's applied to our top track here and what we're going to do is in the Effect Controls panel, I'm going to click the Eight- Point Garbage Matte effect to highlight it.
Once it's activated, you could see these little control points. So we can basically grab these and move these around our subject's face. Now, we're seeing black underneath, to avoid confusion, because we turned off or I turned off the Visibility for Video Track 1 where our original surfer footage is. So we're right now working on the Duplicate. I've created a rough outline around his head. It doesn't have to be perfect. Next, what I'm going to do is apply the Mosaic effect.
Now, I don't want to go in this Presets area, the folder with the stars on. I'm going to just close those up to avoid confusion. I want Stylize, Mosaic, and drag-and- drop that on top of our top layer here. Now as you can see, we already have this area obscured by this Mosaic effect. But I want to improve the quality of the look of this. I mean, the point isn't to just make this look blurred out or to obscure it, I think the point is with this effect is we try to make it as unobtrusive as possible, and still remove what we need to remove.
So I'm going to open up the Mosaic effect. We're going to increase the contrast of the colors by checking the Sharp Colors checkbox, which actually does a better job of obscuring what we have here. Then I'm going to increase the resolution of the blocks by increasing the Horizontal Blocks value, and then increase the Vertical Blocks value. This will change based on your footage, the size, and dimensions of your footage, but I went with 61x36 roughly and that has a good mosaic quality. Again, we could have just made really huge blocks to block out his face, and on that point, I guess we could have just made this area really big too.
But again, I think the point here is that we want to make our obstruction of his face as unobtrusive as possible. We want this to be as clean and look as original as possible. So we still have some facial features. We can tell that there is eyes, and the nose, and the mouth here, and chin, and hair here, and it just really doesn't get in the way too much, but you can't see too many facial features. If you wanted to, you could even increase the resolution by making these blocks more, so we have even finer resolution. But you've got to be careful because it gets to a point where you could actually tell who the person is or maybe what the obscene gesture is and you definitely don't want that.
So somewhere around there is looking pretty good, and again, you can go back to the Eight-Point Garbage Matte to change this if you need to. But that's how to create censored video. We have the duplicate tracks. The one on the bottom is the original. If I take off the visibility on the top there, and then we have a copy on the top with the mask, which is the Eight- Point Garbage Matte, and then an effect like Mosaic or it could be a Blur, but Mosaic is probably most common one, and we put that on top, put that together. Now if we move in time, we have a good censored video.
Now, in this case, the surfer guy moves a little bit, and so, look when he leans his head back a little bit like this, there is some of his head sticks out that's not protected, and that's kind of safe in this case. But then, that also makes it so that the woodlands are also distorted out of view, and we don't really need that. So what you might want to do is select this top layer, and then actually animate its motion. So you can click the layer and then move it around, so that it follows along with the actual layer itself.
In my experience however, once you usually set up the big mosaic area, like a subject's face or his hand, they usually don't move so much that you can actually see it. So usually you can just set it and forget it so to speak, so that you just put it in one spot, and then the subject moves around They're still pretty obscured, no matter where they go.
