Prop animation jitter in UE4

I’m sure this has come up before, but after trying all the solutions posted before the problem persists. Looks fine in Maya and FBXReview. but prop jitters in UE4.
this is going from Maya 2015/2014 to UE4 4.11

things I have tried so far, both in Maya 2015 and 2014

Baking the skeleton every frame on export.
Quaternion and Euler rotation settings in FBX Export
Cleaning up gimbals in baked curves in Maya
Putting prop in root instead of right hand

import with these settings in UE4
2-uncheck Use Default Sample Rate
3-Check import Custom Attributes
4-check Preserve Local transforms

at my wits end here. Any ideas?

Solved… I think

Baked the jittery joints at much higher sample rate… 300fps worked in this instance. Euler filter to clean up most the gimbals, then manually clean up any remaining poops and twitches. A **** pain, but animation looks good in UE4 now.
