Join Ashley Kennedy for an in-depth discussion in this video Writing words onscreen with the Brush tool, part of Editing with Composites and Effects in Avid Media Composer.
There are four Shape tools in the Paint Effect that work very similarly: the Rectangle tool, the Oval tool, the Polygon tool, and the Curve tool. However there's one more tool you can use that doesn't draw shapes, but rather defines brush strokes and paths. Let's take a look at the Brush tool. Okay, so I have my star background again and I want to write the word Nova across this, I want it to gradually just write on. So I can do that in the Paint Effect. I'm going to go ahead and open up my Effect palette, Image > Paint, and drag it on.
And, open up the Effect Editor. And I'm going to click on my Brush Tool button. If you can't see these parameters twirl it down. And inside Brush I have Path, Soft and Size, and you can see that I can basically customize how it looks; diamond shape, circle, we can have various points here. So I'm going to choose this circle, and a little bit smaller. I need to make sure my entire word is connected if I want it to write on over time.
So I'm going to need to do this in cursive. Not the best, but it'll do. So right now it's on screen for the entire time. If we want it to write on, I need to select my first keyframe, also select the shape. I'm going to go with my Selection tool and select the shape. And with my first keyframe selected, I just drag my Path parameter down to 0. And now, it should write on over the duration of the clip.
I think it's going a little slow, so I'm just going to come out of Effect mode and I'm going to trim this up. So I'm just going to enter Trim mode and trim it up, and now it's going to take place over 6 seconds instead. We should go considerably faster here. So if I come in here I can change the Mode to whatever I want. So I'm just going to select the shape, and under Mode I can choose-- we did colorize a few times in the previous movie, I'll choose Emboss.
So I'll go ahead and select this. And I actually accidentally created a new keyframe, I'm going to delete that just so I don't run into any trouble. And now, you can kind of see the stars pass over, which is kind of neat. I'm going to undo and go back to solid. And again, I'm going to delete that keyframe I accidentally created, and let's go ahead and--actually I will keep that keyframe. I'll add a couple of them.
And let's just change the color over time as well. So, I'm just going to select the shape, and select this keyframe, the second one. And we'll move the color from red to yellow, and OK. So it starts off, it's going through the spectrum, and then it's going back to red, except I'm going to just make sure that this is green, and then maybe blue.
So now we should go through the entire spectrum all the way to blue. So that looks nice. And I just want to show you what happens if you don't connect your letters with the Brush tool. I'm going to just make another Brush shape. And this time I'm just going to write the word Nova, like so, just print it.
And then, we select our shape, I'm going to go ahead and select all my keyframes. And want to deselect that shape and just select this one. Now if I select my first keyframe here, I have my shape selected, my first keyframe, and I move my Path to 0. Notice how each one of the letters now is going to form over time. So if I get all of that, and it basically formed from here to there, because I have just one set of keyframes.
So, as you can see, the Brush tool is a great way for you to write on various shapes and patterns. Don't mistake it for a typical Shape Creation tool, because using the Brush tool will not allow you to close shapes in the typical way, so be careful the way you use it.
