How to animate cutscenes?

I’m tying to use some pool of animation for cutscenes, but Matinee and Sequencer can’t blend animations together.
What is a preferred way to make cutscene?
Export to another editor and animate? Can I use blender for it?

you’ll for sure need an outside animation program to do animations with (although you can kinda animate in UE4…and just not nearly as well as other programs)…Blender for sure can do it …
