Question / Help Video on Power Point Presentation Delay

[Cida Conti]

Hi guys! I am trying to record my PPT presentation over OBS. My presentation has some videos and I realized there's a small delay when I go to record. The delay is noted even before recording and for sure after that.. I have no idea how can I fix this issue. Is important to say:

1. the video has also audio
2. there's no problems with FPS
   

Thanks a lot!
