Animations in Maya and UnrealEngine are misaligned

Some parts may be difficult to understand because of the use of translation software.

When I load animation from Maya into UnrealEngine, the animation in Maya and the animation in UnrealEngine are out of sync. Is there a difference in the way keyframes are completed? Is it possible to make the animations match perfectly?

Resolved. It seems that the output with playblast had fewer drawings than the Arnold rendering.
