The question is understanding how the source order is supposed to work. If I start the source, in top position and set it to change to start absolute, it will move the source to the bottom position. The relative position doesnt seem to have an effect at all.
What I am trying to do accomplish, is to have the source move from whatever position it is (e.g. the bottom) to the top position at the start of the move. I don't understand why "start absolute" will move the source to the bottom of the sources. Maybe your plugin cant do what I am trying to do and I am misunderstanding the point of the source order?
For clearer context, I have 3 media sources in the scene, each in their own group, with the filter applied directly to the scene as per usual. I want the source listed at the bottom, to move to the top, before the start of the move transform.
