I'm trying to do this as well. Can this be done?
Hello,
Nice to see I'm not the only one with that needs or issue.
I think "Source deactivate" is the trigger to use and it needs a fix.
If there's no bug in how the triggers work, and/or prevent other users having their scenes not working anymore by changing their behavior, then maybe adding one more trigger could be the solution. Something like "when the source is being actively disabled but still shown in the output". or "at the start of the source hide transition".
Until it's added/fixed, two solutions:
For now, as I'm using this for an alert animation, I'm using streamerbot to trigger both the source's visibility AND its move source filter's visibility at the same time.
If you don't use streamerbot, I guess you could trigger it with another source's filter and set your move animation to "simultaneous trigger".
if you don't have another source to hide at the same time, create one not visible on your scene (transparent picture, or 100% alpha color source).
Hide both sources at the same time, one to trigger the Move source animation, the other to trigger the OBS transition effect.
I didn't try, I just thought about it. Hope it helps until the Move source filter let us trigger filters at the start of a source's hiding transition.
