Imported Camera Animation - Hard Cuts are not hard cuts

I’m having problems with my imported camera animation. In blender we have created a camera animation that has different shots. As example: move trough a restaurant - then the shot changes to a different room - then a different room etc… In blender the shot changes are exactly 1 frame. So there is no transition between the shots it is a hard cut. But when I load this in Unity there actually is a transition. A super fast transition but still noticable. How is this possible and how do I fix this?

Hope that someone can help.

Maybe recreate the animation using cinemachine directly in unity?

how you have imported the camera animation? Can you see your blender camera animation keyframes in unity?
