Kulshreshtha: So we’ve animated the four seasons text and now we’re going to animate in nature in a slightly different way. We’re going to create a mask and then we’re going to animate the mask to reveal the text. So I am going to select the clip down here in the timeline and then go to the effect controls panel and I need to find the in nature text and if I go all the way down to the bottom I can find the object here text in nature. I’m going to click on the triangle to reveal its properties and right below the word text there are three masking tools.
An illisp mask, a four point polygon mask essentially a rectangle and then you can also free draw a mask so I’m going to add a rectangular mask, the four point polygon and it creates a mask by default here in the middle of the screen and the way the mask works is that when in nature is inside of the mask it’s visible and then if it’s outside of the mask it’s invisible. Now you do have to remember that this mask is only going to apply to the in nature text, it’s not going to have any impact on the four seasons text or the rectangle or anything else.
So for now I’m going to reveal the full text just by dragging the corners of the mask like that and now we can start key framing the mask rather than key framing the text we’re going to actually key frame the mask and so I’m going to go to one second here in the timeline and in order to create a key frame for the mask I’m going to go to mask path. I’m going to click on the toggle animation button, it’s going to create one key frame at one second the text is revealed then I’m going to go to the beginning of the timeline and at this point I want to create another key frame and then I want to move the mask away from the text. Right now I can’t see the mask.
When this happens simply click where it says mask one in the effect controls panel that will reveal the mask over here in the program monitor and now for this key frame I’m going to move the mask away from the text and now you can see that the text is revealed. If I go more slowly you can kind of see what’s happening to the mask. This blue box here it’s moving over top of the text and as it moves it reveals the text. Another very useful feature of a mask is that it can be feathered. I’m going to increase the feathering to twenty five.
Feathering is basically fading the edges of the mask to create a softer edge. Now later on in time we’re going to go to four seconds. I’m going to create another key frame and then at the very end of the clip then I’m going to click on mask one to reveal it again and then I’m going to move the mask in the other direction to hide the text and now you can see the movement of the mask. It reveals the text and then it hides the text. It’s kind of a cool little effect. There’s one thing I’d like to change. I don’t in nature to become visible until four seasons come onto the screen. So I’m going to select these two key frames and then I’m going to shift them over in time so now four seasons comes onto the screen then in nature is revealed and they both disappear together. So that’s kind of a cool little effect and this is all done with a mask inside of the effect controls panel.
