During Semester Break... (Replacement)

During the semester break, I have to do a prototype for the Production part, which is the rehearsal part of the band in the form of when the reader slide the video or images, then the video will play it according to the speed of reader slide. It is something like time-lapse video but it's scrollable.

However I go online and search for how to make a time lapse video scrollable in edge, but it seems that there's no way to find out. But from the Google search, it does come out some few options.

One of it was I found it in Adobe Communities, someone ask the same question as me.

Some people indeed provide one solution for it.

When I click on it, it come out with this solution with somebody's blog.

Then I download the source file that she provided, and try it out in Edge Animate.
