I see. Have you tried using the in-game camera feature? It records frame by frame, so you always get smooth video. 99.9% of the particle effects I use just about lock up the game. But they look so good when recorded with the in-game camera.
My game lags when my park is doing well. That's when there are tons of guests, scenery and rides causing my game to lag. It's extremely horrible at night in the game. I don't think I could make a video even if I tried. My game would probably just crash.

My favorite video would be Blue Giant. That video is just addictive!
