First off, I understand that this is not a programming question but it is related to a web development project I am working on so I figured I may as well try it here.
I am editing a video in Adobe Premiere Pro. In that video I would like to add some simple animations (for example, a circle drawing itself around a specific part of the video that I want to draw attention to). For those animations, I am using Adobe Animate (formerly Flash). However, I so far haven't found a way to export the animation without a background so that for example only the self-drawing circle is visible.
I know that this is possible when exporting a swf but I need the format to be mp4 so that I can properly use it in Premiere Pro (at least as far as I know that's the format I need to use).
