Questions about how to create a blueprint for the camera rig

I’m looking to implement the C4D Camera rig created from the YouTube link below in Unreal.
C4D Tutorial - Aligning a Camera to a Spline! - YouTube

The current blue print is as follows.

All work normally, but only in a play environment.
What I want to do is write this blueprint as a tool to catch camera animation via sequencer in viewport state.
I would appreciate it if you could tell me how to do this blueprint to work normally in viewport state.

Hello, first thing to mention is that there is a camera rig rail asset that you can use to create animations in sequencer for cameras like in the video you attached.

Alternatively, you may be able to use take recorder to capture the animation of your actor from simulation/play, and then add the animation into sequencer.

I’m not used to using a camera crane or camera rail, so I’m going to make it with a blue print and use it.
The way you told me is a good way, but it’s not the way I want it to be.
Thank you for your reply.
