SMF - Just Installed!
There is a effect that is like shaking the screen for a dangerous situation?
VFX_FNF_SCREEN_SHAKE and/or VFX_FNF_SCREEN_BUMP.
i'd use both at the same time, does the trick.
Caveat - I find that shaking the screen in cutscenes messes up the camera settings, so better to use these effects in ordinary gameplay.
