Camera cinematic transition

hello, i want to make a PT like camera transition between levels. in the following drawing the red is level 1 and green is level 2. the camera should go from point 1 to point 2 and when it reaches the point 2 to unload level 1 and load level 2. i tried having a second camera, getting the characters world location and then from there use this camera only for the cinematic, but it didn’t work. any suggestions?
