KeyframeActions

KeyframeActions

is an option for Manipulate and related functions that gives a list of times and control settings.

Details

  • KeyframeActions specify interesting controls settings for a dynamic expression that gets rendered at a given time in a video. It is typically used for creating animations from experiments.
  • Possible settings include:
  • {t1:>actions1,…}a list of times and the associated parameter actions
    {assoc1,…}a list of associations of keyframe action specifications
  • Each actionsi should be a list of settings for different variables in the form of {u=ui,v=vi,…}.
  • Possible keys for associ are:
  • "Time"the time associated with the bookmark
    "Actions"setting of the controls
    "Label"a label for the bookmark
  • Video[Manipulate[…]] looks into keyframe actions when creating the video file.
  • In Manipulate, use KeyframeActionsTrue to enable interactive addition of keyframes using the graphical user interface.

Basic Examples  (1)

Enable interactive setting of keyframe actions:

Wolfram Language code: Manipulate[x ^ 2, {x, 0, 1}, KeyframeActions -> True]

Specify explicit keyframe actions:

Wolfram Language code: Manipulate[x ^ 2, {x, 0, 1}, KeyframeActions -> {0 :> {x = 0}, 1 :> {x = .5}, 2 :> {x = .5}, 3 :> {x = 0}, 5 :> {x = 1}}]
Wolfram Language code: VideoGenerator[%, 5]

Scope  (1)

Specify the KeyframeActions as a list of associations:

Wolfram Language code: Manipulate[x ^ 2, {x, 0, 1}, KeyframeActions -> {<|"Time" -> 0, "Actions" :> {x = 0}, "Label" -> "1"|>, <|"Time" -> 1, "Actions" :> {x = .5}, "Label" -> "2"|>, <|"Time" -> 2, "Actions" :> {x = .5}, "Label" -> "3"|>, <|"Time" -> 3, "Actions" :> {x = 0}, "Label" -> "4"|>, <|"Time" -> 5, "Actions" :> {x = 1}, "Label" -> "5"|>}]
