Opacity Effect


Opacity Effect icon Opacity Effect (Opacity Effect) sets the video Opacity (transparency level). Opacity animation allows you to fade the video image in and/or out.

  • Name - A short name to that will identify the effect's purpose.
  • From - Starting value for the effect. The effect animation continues to the To value.
  • To - Ending value for the effect.
  • Apply a From Value - When checked, the effect uses the From value. If not checked, the effect will begin at the current value.

See the Timing section for details on timing the animation of the effect. See the Motion Behavior section for details on modifying the default behavior of the effect.

Target Values

  • Valid Range 0.0 to 1.0
  • Special Values - Value of 0 is no opacity (fully transparent). Value of 1 is full opacity (no transparency).

Favorite Values

As a productivity aid, you can save the entire effect (all values on all tabs) as a Favorite with the Save as Favorite Values button. Then you can set all values of an effect from the Favorite values using the Set from Favorite Values button. Separate favorites are saved for each type of effect (Opacity, rotation, etc).

Opacity Example

In the sample Screen below , we set the Screen Background Image to the Robot Head (PNG file) and specify Image Layout to Stretch (Figure 5). The Video File is set to Robotic_Welding.MPG (Figure 4). And the Screen Opacity is set to 0.5 (50%). Notice how the Background Image comes through the video (Figure 3) when played.
