The Format media action enables you to adjust the appearance and settings of images and videos on a Keynote slide, allowing you to apply styling and alignment options to customize how media is displayed in your presentation.

Settings

  • Use the Session name field to select one of the following options:
    • Session name: Enter the name of the session used to open the presentation with the Open action.

      (Optional) Click the Insert a value icon to select an existing variable that you have used to store the default session name.

    • Variable: Enter the name of the variable that you have used to store the session name.
  • In the Media details option, specify the following details:
    • File info: Specify the file name of the media with the extension as mentioned in the Keynote slide.
      Note: On your Keynote slide, click the image and go to the Image section on the right-hand side to view the file information.
    • X coordinate and Y coordinate: Specify the X and Y coordinates to set the position of the media. X (from left) sets the horizontal position; Y (from top) sets the vertical position. Coordinates (0,0) start from the top-left corner of the slide. Increase X to move right, Y to move down.
  • In the Format options, select one of the following settings to format your media.
    • Basic: Set either Width or Height. The other dimension adjusts automatically to preserve the aspect ratio.
    • Script: Specify instructions for formatting a media object in Keynote. See Example script syntax and structure.

Example script syntax and structure

You can use the Script option to specify instructions to format a media file in the Keynote. Instead of filling out separate form fields (like X coordinate, Y coordinate, Width, or Height), you can write a short command block that defines how the action should behave.
Note: When specifying a script, the properties within quotation marks currently cannot be set. For example, 
set description to "this is the added description"
A typical script uses simple key-value pairs or function-like commands to specify the properties of a specific media. A general script to format an image looks like this:
set position to {100, 100}
set width to 600
set height to 400
set opacity to 90
set reflection showing to true
set reflection value to 100
set rotation to 10
set locked to true
A general script to format a video looks like this:
set position to {100, 100}
set width to 600
set height to 400
set movie volume to 0
set opacity to 80
set reflection showing to true
set reflection value to 20
set repetition method to loop
set rotation to 20
set locked to false
