@Yasmine91 I haven't messed with this particular file much, so someone else may have a better idea. But it's possible that the game can't use one of the settings you're imposing so it reverts to default. I'd suggest changing one setting at a time, preferably one where there are reports that the exact setting (not just what you're changing but the value you're using) works for other people.
Please also double-check that after you've loaded the game once, the changes you've made to VideoCamera.ini are still present.
