Kulshreshtha: So we’re now going to adjust the pacing and the timing of our animation. This is how it looks so far. I’m going to take my play head to the word compass and then let’s say that we wanted the word compass to come on to the screen a little bit more slowly. By clicking on the compass clip and then moving up into the effect controls panel you can see the key frames, the two key frames. Now if I move the key frames and I can simply drag the second key frame and if I move the second key frame further away from the first key frame it will actually move more slowly. You can see that. I’ve slowed down the animation and if I move the key frame closer to the first key frame then the animation is going to move faster so it’s the same amount of change but over a smaller period of time or a greater period of time can allow me to change the pacing.
Now let’s say I want it to be more precise, let’s say right now the original distance between the two key frames was ten frames I could go to exactly 1.15 and then I could move the key frame so that it snaps at exactly 1.15 and now the word compass comes a little bit more slowly onto the screen. I can also do that for the word travels. I’ll click on travels in this case I’m going to move to exactly 2.15 that’s 2 seconds and 15 frames and then I can drag the second key frame so that it snaps to my play head and now I have made the word travels come on to the screen a little bit more slowly. You could also move clips within the timeline so if I wanted the two words to come onto the screen simultaneously I could shift them so now that the two words compass travels come onto the screen at the same time I’ll undo that.
Another way to change the animation or to refine the animation is to change actual values in the key frames. For example, if I move to the circle layer and right now it’s scaling from 0 to 100 but let’s say I want it to scale from 0 which is the first key frame to 110 meaning the circle should become a little bit larger. Now what I recommend if you’re planning to change one of the values in the key frames be sure to use these white arrows. Go to previous key frame, go to next key frame.
Sometimes people often just drag the play head or click on a key frame or something like that but I highly recommend using the white arrow keys to be as precise as possible so I can go to the second key frame and I can simply change. I’m going to manually change the value up to 110 and now you’ll notice the circle gets a little bit larger and as I go from the first key frame to the next key frame now the circle goes up to 110% of its original values. So there are all sorts of things that you can do.
You know the possibilities are endless here in terms of making animations faster or slower or simultaneous or shifting them a little bit, shifting the position a little bit, shifting the scale or the rotation a little bit. Once you get the hang of it it’s completely up to you how you would like your animation to flow.
