Quote To use different templates of the video collage function in a music video clip, I would need to cut 4 different videos on the tracks in exaclty the same pre-cuts. Is there an efficient way to do this? All tutorials just show how to pre cut one track, not various at the same time to get the same time markers.

Thanks

If I understand correctly, you want to cut more than one clip at the same time.
A way to do it, right on the timeline.
Add each clip to a track on the timeline.
Example: 4 Tracks, each with 1 video, one underneath the other.
Select all videos, position the cursor at the position you are going to cut at the beginning, and Split button, select and delete the leftovers on the left.
Do the same to cut at the end, select and delete the leftovers on the right.
