Reversing the comp’s Y coordinates
I’m looking to move the Y zero coordinate from the top of the frame to the bottom, so it will match some tracking data from PFTrack. If there is a solution, please tell me where to type the expression as well. I’ve never had to use one before.
Thank you.

I think you would apply an expression like this to the position property:
[value[0],thisComp.height – value[1]]
That should move y = 0 to the bottom, and +y will be up. Is that what you were after?

That sounds like what I’m looking for. But I should have mentioned, I’ve never applied an expression before. How is it done?

Just alt click the position stopwatch and paste in the expression text.

Yes. Good. It seems to work. Thanks for that.
