How should I do the final render using the composure function?

In many tutorials, I have seen that Unreal composure is used to render until the end, but I cannot render with them, and actor-only rendering is having difficulty because the media layer is not rendered together.
So, I rendered the actors and shadows separately and composited them into the actual video.
But this is not the workflow I want.
I wanted a simpler workflow, so I tried to use the composure feature, but it didn’t work as I wanted.
The media source used ‘.mov.’ directly,
I tried it in UE5.2 /UE4.27 and it all failed.
I wonder if anyone has a solution to this problem.
