I don’t understand what this means. Do you mean, “when I zoom out”?
If that is what you mean, then there’s a few questions that need to be answered:
Was this created in the Sequencer or is that a Blueprint-only demonstration? (You used “keyframe” but I want to make sure, just to be safe…)
Do the objects on screen have collision? If so, press “ALT” + “C” to show those collisions. I suspect the camera is bumping into something.
2a. If it is bumping into something, you can change the collision behavior to “overlap” if you require some trigger to occur, or disable collision altogether if there is no trigger required.
Is your camera the actor or is it attached to an actor? Does this actor have collision?
You see, nothing is simple. You have to really think about what you’re doing in a wholistic way.
