UPDATE:
So after a little tweaking I think it is acceptable in the current format for most use cases. There is still the necessity to very slightly tweak the top SPR filter when resizing sometimes, and I can’t seem to get around that. However, I did discover that if I set up all the filters on a smaller box, it scales up much better and is easy to adjust without weird results (the vertical lines end up wider but are easily clipped in the top SPR filter and there is no odd behaviour, which I experienced when sizing down a larger box).
Also, be aware, the interpolation choice that is enabled in the settings menu should match the export option, or you don’t get exactly what the preview shows, at least I didn’t (even with no proxy and no scaling). I’m pretty sure most of my issues here are due to the mask percentages, but this is about as close as I can get it, and I did use a green color block to view all the masks and position them.
Duplicate the first box then move by dragging the bottom SPR filter and resizing to the length of the word. Then tidy up by adjusting the top SPR filter (position and size) if necessary. See my mlt for examples of this.
If pixel perfect precision with super sharp lines is a requirement then maybe it’s back to all SPR filters. I suspect someone more advanced can do better than this, since I’m really still a beginner, closing in on intermediate.
