How can I render a cutscene in a proper way with seqeucner

The sequencer “Render movie” option is ridiculous…
I want to render a movie in 1080p 60fps (10 seconds of movie) but UE4 doesn’t take its time to render the video properly. The result is when I watch the movie rendered, it lags bad. It’s the same with 30/25/24 fps.
P.S. I play in ultra setting and I have fixed 60+ fps when I play my game that is full of particles, animations and other stuff. So the rendered movie’s lag doesn’t depend on my hardware.
