How do I adjust my transitions between 6000 looks? – timing and easing effects

Topic

  • How do I adjust my transitions between 6000 looks? - timing and easing effects

Environment

  • Product Family: Control System, Software 
  • Product:
  • Components: VP-6000
  • Control System: Show Control System (SCS)

Steps

  1. Login to the VP-6000. Refer to How do I log into the 6000 user interface?, DD3769209.

  2. Click the User icon in the top right corner to expand the right side menu and click Advanced.

  3. Click Vidprocs from list of advanced options and then click the line with the type JavaScript Video Processing Engine.
  4. From the Scripts tab, a list of .js files will be viewable. From the list of .js files, click config.js.  
  5. Scroll down within the configuration editor.  The boot up default look is near the middle. 
    Note: In rev 22.0+, a 0.5s transition time is available by default

Transition Timing in the config.js file:

//Create_ChangeTransitionTime(name, duration);
Create_ChangeTransitionTime("Time_0s", 0);
Create_ChangeTransitionTime("Time_0p1s", 0.1);
Create_ChangeTransitionTime("Time_0p3s", 0.3);
Create_ChangeTransitionTime("Time_1s", 1);
Create_ChangeTransitionTime("Time_2s", 2);
Create_ChangeTransitionTime("Time_5s", 5);
Create_ChangeTransitionTime("Time_10_s", 10);
Explanation: 
These commands create triggers that change the transition duration. The 2nd argument is the duration in seconds. Fractional times are allowed (as demonstrated above). You can add as many copies of this command as you need.

Transition Easing or Effects

Transition timing functions for changing looks.

//Create_ChangeTransitionEasing_Linear(name);
Create_ChangeTransitionEasing_Linear("Ease_Linear");

// Create_ChangeTransitionEasing_Bounce(name, bounce_count);
Create_ChangeTransitionEasing_Bounce("Ease_Bounce_1", 1);
Create_ChangeTransitionEasing_Bounce("Ease_Bounce_3", 3);

// Create_ChangeTransitionEasing_SymmetricBezier(name, x, y);
Create_ChangeTransitionEasing_SymmetricBezier("Ease_SFS_", 0.8, 0.2);
Create_ChangeTransitionEasing_SymmetricBezier("Ease_FSF_", 0.2, 0.8);

// Create_ChangeTransitionEasing_Bezier(name, x1, y1, x2, y2);
Create_ChangeTransitionEasing_Bezier("Ease_Bezier", 0.17, 0.67, 0.83, 0.67);

Explanation:
These commands change the transition easing function. An easing function changes how a transition progresses over time. A "linear" ease is the default and doesn't actually change anything. It maintains the same behavior over the duration.  

The example below shows linear and Bezier behavior. The cyan box is a linear ease and the magenta box is a Bezier ease. 
  • A "bounce" ease makes the transition bounce a configurable number of times at the end of the transition (like a dropped ball). A "Bezier" ease is the same as what's shown on the http://cubic-bezier.com/ website. The 4 numbers at the top of the page can be inserted as the 4 arguments to the command to get the same ease effect.
  • A "SymmetricBezier" is a simpler form of a Bezier ease where the 2nd control point is placed in position that mirrors the 1st control point. This makes the ease symmetric (does the same thing running forwards or backwards).

More examples can be created / seen at http://cubic-bezier.com - click the "Go" button and watch the cyan and magenta boxes just below.
