Thank you. Maybe I'm stupid but I couldn't figure out the UI on the split screen effect. All I could see was checkerboard and some dotted lines. I tried playing around with them, to no avail. I've asked NCH if they have a video tutorial for split screen; waiting for reply. The videos I saw (not by NCH) on YT are just junk. Meantime, I was able to combine two effects, CROP, and POSITION (and using overlay as you suggested) to accomplish the result. Thank you so much!
