Question | Sync Unreal Sequence and Physical Camera Record

We are running a virtual production and due to some project specifics that i can’t discuss we need to sync the camera record and unreal sequence record so that the video from the physical camera and the Unreal Sequence start and stop recording at the same time - The Unreal Sequence is not recording video, just positional data.

It can be either:

A: Starting/stopping record in Unreal starts/stops record on the physical camera
B: Starting/stopping record on the physical camera starts/stops record on the Unreal Sequence

Ideally what we’d want is to have the SDI Flag Cue Unreal Sequence to record

Does anyone have a working elegant solution for this or is anyone available to build one as a paid contract?

Currently using:

Unreal version: 5.2
Physical camera: Red Raptor
Capture card: Black Magic DeckLink 8K Pro

Thanks in advance

Bumping - Has anyone figured out a solution to this in the past or have and idea of something that may work?
