[ownerer] “I hope I was clear now.”
Not yet 🙁
Telling us what’s on each of the tracks and why they’re there might help.
You originally said use one effect on multiple tracks but not on the whole output video.
I’m not sure why my original reply wasn’t satisfactory as it’s what you were asking to do.
Are you sure you mean track (a bunch of clips) and not event (an individual clip)?
