Having Problems with Media player when rendering out footage.

Hi guys,

Im wondering if anyone has any clues as to why when i start rendering out footage from my scene, my media player footage plays for 3 seconds before restarting to the beginning. The overall clip is for 51 seconds and works perfectly in viewport.

I have tried to edit some of the blueprint settings, including (unthinned) frame rates on (supported rates node)
rendering out in same frame rate to the original clip in the media player etc…

Timespan from (make media play options node) etc…

Do you think it is down to my computers overall power and GPU?
