I have these lines in my ~/.xinitrc file:

# turn off Display Power Management Service (DPMS)
xset -dpms
setterm -blank 0 -powerdown 0

# turn off black Screensaver
xset s off

If you want your screensaver to be paused only when you watch a movie you can use xssproxy. It's available as a debian package as well as a NixOS package.
