I am currently playing about with an animation for a picture I sketched of cars queueing. As part of the sketch I wanted each of 3 cars in the sketch to passively vibrate from side-to-side, so I created a frame animation for each.
The problem is getting the images back into a master PS file with an ordinary layer timeline where I can animate them back together. I referred to this answer but exporting as .mov with a transparency channel does not seem to work, all videos are coming back into the document without transparency.
I can't comment on the post in question because I don't have enough rep unfortunately. The reason that I require transparency is because the images need to overlap and disappear/reappear independently of each other. Below is one such frame animation I want to render with transparency to put back into a master sequence
