I love this plugin and use it daily. However, there is some strange behavior that I would assume is a bug but perhaps it's a user error. I have a set of user commands for quickly moving the position values of my footage. when I hit control and an arrow key it will nudge the footage up, down, left or right in increments of 10 values. It usually works great but for no discernable reason, the values will reverse. up will be down, left will be right, etc. I can go in and manually fix the behaviors to work the way I expect them to but then at some point once again they will reverse. When rebooting the software it seems to be a coin toss as to which direction the function will make my footage move.
to reproduce this on your end I guess you would set up a user macro of the position and make sure the action is set to modify value. on my end the x y coordinates will reverse themselves where values that were supposed to be positives will become negatives and vice versa. otherwise, these functions work fine and nothing else changes.
I am running premiere pro 24.3.0 and the firmware version 1.2.3 of Excalibur. I am using an Apple M1 Max with the top of the line settings in all metrics.
Here's an image of what the user command looks like and you can see in the list the related position user commands I have set up. It seems to affect ALL of them when the bug occurs. I don't think I've ever seen it affect just some it's all or nothing.
