I'm building a custom Fusion template in DaVinci Resolve for my own editing workflow that creates a split screen effect for Podcast Editing.
It takes a single video input
It positions and scales the video using a Transform node
It crops the video using a RectangleMask, showing only the top or bottom half of the frame
It has a button control to toggle between showing the top half or bottom half of the video
It also has sliders to control the position (X and Y) and size of the visible area
The idea is to create a split screen effect where the same clip is shown cropped in a specific region of the frame.
The problem is that this template was built and calibrated for a 16:9 timeline. When I switch to a 9:16 timeline, the entire effect gets squished and distorted.
I don't want the template to adapt to the new resolution. I actually want the opposite. I want it to always behave as if the timeline is 16:9, even when placed on a 9:16 timeline. The visual result should look exactly the same regardless of which timeline resolution I'm working on.
How can I do that?
