It is only useful as a shared plugin (i.e. a multitrack plugin). To use the overlay plugin: 1. Add the effect to Track A. 2. Choose attach effect from the context menu of another track (Track B). 3. Choose Track A: Overlay as a shared plugin. 4. Manipulate the plugin parameters in Track A. ==== but in pdf doc I see this paragraph: In the Overlay Plugin’s parameter window you can choose the overlay order, i.e. which track plays the role of the "bottom layer" and which plays the role of the "top layer". For some overlay modes, this can make quite a difference, e.g. the top layer is subtracted from the bottom layer for "Subtractive" mode. Further on, you can choose on which of the tracks to overlay the combined output. (Hint: in most cases, you will want to mute the other track and only retain this combined output). +++++ /storage/emulated/0/Download/cinelerracvmanualen.683533262.pdf downloaded from https://usermanual.wiki/Document/cinelerracvmanualen.683533262/view while manual claims to be same 1.63 en version I do not see this paragraph in wiki?
