Website HomeEffect - Timing Values
Overview
You time an effect animation by setting a Start At time (time from the beginning of the video) and a Duration time (how long the effect will continue to animate). The effect begins to execute at the Start At time. The Target value of the effect will increment from the From Target value to the To Target value over the Duration time (typically a number of seconds). So the calculated speed of a given effect animation will depend on these three values (To, From and Duration). Enter the time values in the respective Minutes,Seconds and Milliseconds fields.
Setting the Duration to zero (0) will cause the effect to jump directly to the To Target value immediately when it executes at its Start At time.
If you do not specify a From Target value by checking the Apply a From Value checkbox , the current value will be used as the From value. This provides a way to chain effects over time and have each subsequent effect resume value changes where the previous one ended.
The Media Item Length is determined when you load the video using the Load button in the Play Controls section of the application. The Set to End button will not work until the length of the video is known by loading it. However, you can set the times manually without preloading the Media Item. A warning message will appear if you have not preloaded a Media Item.
Initial Play Values
When you click the Play button, the video will be in an initial state as follows:
- Scale: Set based on the option chosen in the Play Modifiers for Play Screen Size.
- Rotation: 0 degrees.
- Skew: 0 degrees for X and Y.
- Opacity: 1.0, full opacity.
- Translation: Positioned at upper left corner of Play Screen (0,0)..
Favorite Time Values
As a productivity aid, you can save the Start At time and Duration as a Favorite with the Save as Favorite Times button. Then you can set either of these values on future effects by using the Set from Favorite buttons.
