Thanks for the quick response. I've actually tried the method you suggested.
I wanted to know if there was a way to achieve this that was less labour intensive. I plan to have several scenes and it would speed up production time if I had a symbol that I could copy and paste into each scene that would:
-calculate the duration of the scene
-automatically set the time of the progress bar to automatically match the length (in time) of the scene
Please let me know how something like this could be made possible.
