Hell guys!

We want to create mix reality.
We have delay 1-2 second in our chromo key video because we use very slow capture card. That why we have a problem. Our Treker working in real time without delay but our streem video with delay. We cant change capture cart becuse we have not money. That why we want to create delay in htc tracker position and rotation, but we dont understend how do it.

We use this tutorual https://www.youtube.com/watch?v=kuBI1VoJbPg&t=174s
