Sync Motion Capture with Captured audio

Currently we’re recording motion capture as well as live audio to go along with this. We currently have everything sync’d up with time code, which is all well and good. however what is the process of piecing all these back together inside unreal if we were to use a real time cut scene rather than a rendered video? Or once we get the animation back inside the engine how do we then sync audio up in it correct frames?

As I cannot find anything regarding Time Code so unsure how to correctly go about this

Many thanks

I would really like to hear an answer to this too!!.. the only documentation I can find is for syncing to a video-input via Blackmagic… but we’re not doing this. We have an fbx with timecode embedded (or a LiveLink stream), and an audio file with timecode embedded…

how do we align them in-engine?!?!?!??
