  Changing text position by determining character length

  Posted by Tonmoy Moves on February 23, 2021 at 3:05 am

  Hi, I am trying to create a custom lower-third and export it as a mogrt. It’s a simple name tag in a simple format – [Title + First Name] [Last Name] [Affiliations]. The reason why they have to be separate is because they all have some unique formatting style. So my question is: How do I dynamically change the position of the 2nd and 3rd text boxes based on the character length of the 1st box?

  The easiest way is to parent the 3rd to the 2nd and the 2nd to the first word.

  Then give 2nd and 3rd words position properties both this expression:

  [20,0] + [parent.sourceRectAtTime().width,0];

  20 in this case is the horizontal margin between the words.
