How to convert Control Rig Pose to Animation Sequence?

Development Character & Animation
1

I was doing MetaHuman lip synchronization, and I used some Animation Sequence resources.

Then I used Blend Poses in Animation Blueprint to do the mixing. But my Animation Sequence resources were not perfect, causing some lip matching to be incorrect.

I want to use the Control Rig Pose that comes with MetaHuman to regenerate the Animation Sequence. How should I do it?

I don’t know anything about animation.
