How to use AE repeaters to design MG cartoons

php editor Xigua brings you the operating skills of AE using repeaters to design MG cartoons. Using repeaters in AE software can easily perform various processing and modifications on MG animations, improving work efficiency and production quality. During use, there are also some details and techniques that need to be paid attention to, such as how to correctly install, use and edit repeaters, etc. Next, let’s learn more about how to use repeaters to design MG cartoons in AE!

1. Create a new 1920*1080 synthesis, 10s, 30 frames/s. The parameters are for reference only. You can decide according to the design requirements. Create a new solid layer, blue, the composition is too small. Create a new rectangular shape layer with a stroke of 25, set the fill as desired, and set the anchor point to the midpoint of the rectangle. Click on the rectangle layer and adjust the fill opacity to 0%.

When selecting keyframe animation, do 0s--1s (rectangular) keyframe animation. The stroke width parameter changes to (0 seconds is 25, 1 second is 0); the rectangular path size parameter changes to (0 seconds is (123.4, 123.4), 1 second is (0.0, 0.0)); [Change: Rectangle 1] The position parameter under the attribute changes to (0 seconds at (0.0, -4.0), 1 second at (0.0, -531.0), which is the movement path flying vertically from the midpoint of the layer to the edge of the top layer); [Change: Rectangle 1] The scale parameter under attributes changes to (0 seconds (0.0, 0.0%), 1 second (100.0, 100.0%)). Then, select all keyframes and press F9, and select [Edit Speed ​​Chart] through [Chart Editor] to enable Rectangular movement is smooth.

3. Set the rectangle into a group. Select the [Content] attribute of [Shape Layer 1], click the [Add] button on the right side, and select [Group (Empty)] in the pop-up menu. Then drag [Rectangle 1] to [Group 1], select the [Content] attribute of [Shape Layer 1] again, then click the [Add] button on the right side of it, and select [Repeater] in the pop-up menu 】.

4. Expand the properties of [Repeater 1], set the parameter [Copy] to [9], and set the [Position] property under [Transformation: Repeater 1] Change to (0.0,0.0). At this time, all [Copies] of [Rectangle 1] are coincident at this position. The [Rotation] attribute under [Transformation: Repeater 1] is set to [40°] (that is, 360 °/9, so that 9 copies have been set up to be evenly distributed on the circumference.), and you can create more interesting situations by playing with other attributes. Shorten the composition timeline to about 1s10 frames. This step is the focus of this lesson. The use of [Repeater]. I don’t know why it is translated like this. It is called [Copy Machine]. It is actually easier to understand.

5. Select [Shape Layer 1], press Ctrl D, copy a layer, and drag the newly copied layer [Shape Layer 2] back about 6 frames. Select the layer and press the U key to expand the keyframes, move the [Current Time Indicator] to the first keyframe, change the [Stroke Width] to 0, delete the [Stroke]; change the fill opacity to [100] 】.

6. Select [Shape Layer 2], press the R key to bring up the rotation attributes, put the [Current Time Indicator] after 10 frames, and change the rotation to 45°. And add keyframes, move the [Current Time Indicator] to 1s, add a 65° keyframe; close [Shape Layer 2] and press the UU key to expand the keyframes, and change the copy under [Repeater 1] It is [12], and then the [Rotation] attribute under [Transformation: Repeater 1] is set to [360°/12=30°].

7. Select [Shape Layer 2] and press Ctrl D to copy a layer of [Shape Layer 3]. Also move this layer a few frames behind on the timeline. Then, double-click the U key to pop up the keyframed attributes. Move the [Current Time Indicator] to the starting position of the layer, select the [Scale] attribute under [Change: Rectangle 1] under [Shape Layer 3], change the parameter to 100, and then change the next Keyframe, change this attribute parameter to 0; select the [Size] attribute under [Rectangular Path 1], change the parameter to 0 at the starting position, then move to the next keyframe, click the [Constraint Proportion] option box, and cancel Constraint, change the width of the size to 10 and the height parameter to 523. At the same time, select the [Position] attribute under [Transform] and change it to -1000.

8. Through the operation of three groups of shape layers, you should have a better understanding of the basic use of repeaters, and then you can make some more layer changes according to design needs. , to make MG richer and more beautiful.
