Switch Shots, Stutters

Good Evening,

I have a layer that has a video (268mb, 1920x1080, h.264, MP4) then another layer with a live RTMP stream ingest side-by-side with another video (96mb, 1920x1080, h.264, MP4) then another layer with static text.

Everytime I switch to the scene it stutters for like two seconds causing audio to stop, video to freeze, etc. Then bam it's all perfect.


I've tried just going over to just a video file and it also stutters. I am guessing it is something to do with it loading the videos up before playing them but it causes some issues with our livestream. 


Our viewership is generally tens of thousands concurrent so it's crucial to have a very smooth system.
