Franz, I think I have the solution (or at least a solution) for you, which you should be able to use no problem in Action TL transitions (though I haven’t tried it there). I’m attaching a Batch from 2021.1.1, as well as just an Action with no media inputs.
It’s just adding a left, right, top, bottom surface around the unaffected center surface. Then gmasking off each exterior image (in this case HD rez) until there is only a 1 pixel sliver edge on each of the sides. Then with an axis offset on each, scaling heavy in X or Y. Plus 4 corners.
The center image is unaffected, and when you scale the whole pod of surfaces down, you have exactly what 2d transform in Batch gives you with Repeat last, scaled down.
Attached is a screen shot showing Batch 2d transform example on the left, Action output (with everything scaled down to 50% like in 2d transform), and the Action schematic on the right. (Footage talents are blurred to protect the not-so-innocent).
*I made this using an HD source, so using higher res you might have to offset positionings - or Apply+Scale the action might do it.
Why did I take half an hour of my day to do this? Because if I do one more Beauty shot I’m going to lose my sh*t. This was a nice vacation, so thank you.
