OUGD202 - After Effects - Workshop 5

Todays topics:-

- key framing techniques
- simplifying compositions // "grouping" layers (not called grouping)
- audio


Highlighting all the layers shows all the animated information in the composition panel.


Describing the movement - at the moment its move from left to right at a consistent speed.

How can we make this more realistic?

Car example - accelerates(easing out), moves at a consistent pace then decelerates(easing in).

The dotted line represents how fast the frames in each second are happening. These four solids are all moving at the same pace throughout the motion as the dots are all in line with each other.


Ease Out.


Animation - animation assistant - choose ease out


You will see the change of position of the solid in the composition panel


Zoom in and the dots representing the frames are closer together nearer the beginning of the motion.


Ease In

Same as ease out but applied to the opposite end of the keyframe.



Easy Ease.

This applies ease in and out to both keyframes at once so it will accelerate and decelerate without you having to apply it yourself. This option is only for even acceleration and deceleration on both sides.



GRAPH EDITOR


toggle switch

changes your timeline panel to a graph



you have to select an animation on a layer to see anythign on the graph



Speed goes vertically on the left hand side and the time goes along the top.

Editing compositions in the graph. The keyframes act like anchor points and you can edit them to create smoother motions. Its much quicker and easier than editing it yourself by eye. Very useful for editing the ease in and ease out functions.





Setting the ease in and ease out yourself in the graph.


Moving the keyframes up and down the speed axis to change the speed of the motion.




Pendulum task.








 "GROUPING" within affect effects


Parent Child relationships.

setting one layer to be the "parent" of all the other layers - anything you do to this layer will happen to the other layers.

Layer switches - toggle switches/modes

position - they all move in relation to the parent layer
rotation - the child layers move around the parent layer
scale - all the layers change scale in relation to the parent layer

You can create more complex movements, animating the child layers individually and then creating a parent layer so the child layers still move and change to how you have animated them but they will do this whilst moving in relation to the parent layer. Multiple orbits is a good example of this the Moon orbits the Earth the Earth orbits the Sun. This is considered to be a multiple parent child relationship/grouping.

All properties apart from Opacity are linked when working with parent child layers.

Nesting compositions.
