What are Actions?

An action modifies a clip’s properties over time. For example, if you want to slowly scale up your screen recording, you create a Video Action on the clip, then modify the Scale property in the Video Properties panel.

Actions are always part of a clip. They are represented in the Timeline with a colored rectangle.

Here is an example of a Video Action which starts at time 1.5s (1.5 seconds) and continues to time 2s (2 seconds):

Actions only affect certain Properties.

There are four action types (Video, Audio, Callout, Screen Recording). Each action type controls different Properties. For example, the clip Scale property is controlled by a Video Action, whereas the clip audio volume is controlled by a Audio Action.

Action Duration – Callout.

The duration of a Callout Action defines how long the callout is in effect. For example, if you have a Callout action that highlights the Mouse Pointer and starts at time 1s (1 second) and continues until time 2s (2 seconds), the Mouse Pointer is highlighted for 1 second. Before 1s and after 2s, the Mouse Pointer is not highlighted.

Action Duration – Video, Audio, Screen Recording.

The other actions are different. They define how long to take to transition between two states. For example, in the above image, if the Opacity of the clip (see Video Properties) is set to zero at time 0, and is set to 100% at time 2s, then the purple Video area defines how long it takes for the Opacity to ramp up from 0 to 100% – in the above example image, 2 seconds.

Curve Type.

By default, actions are applied to the clip in a linear manner, so that for example a scaling goes from the starting size to the ending size, changing the size by equal amounts for each frame. This may be perceived as too abrupt, so you can modify the rate with which an action is applied. Curve Type in the Actions menu has the following submenu options:

Default Linear transition.
Ease-In Starting slow, speeding up towards the end.
Ease-Out Starting fast, slowing down towards the end.
Ease-In & Out Starting and ending slowly, faster in the middle.
None Apply action immediately. The duration of the action does not matter.
Overlapping Actions.

Actions can be overlapped as long as they are different types. For example, you can overlap a Video Action and an Audio Action, but you cannot overlap two Video Actions.

Actions.

There are four actions available:
