It isn't really that onerous, they aren't expecting you to do anything.
Rather, they want the right to film commercially on their own property without getting consent of everyone walking by. Many years ago a local casino was being used for a movie shoot, there were signs at the door saying that they're shooting a movie in here, if you're inside the casino it's possible you'll show up in the background of a shot. By entering you agree to this. An apartment can't do something like that because not entering is not a realistic option, so they're putting it in the rental agreement instead.
In that case they might just not film everyone passing by, it's not hard, it's an apartment complex, just max 1-2 people in a frame. Not hard to ask them. Or work as actors themselves. It's not like there's hundred of tenants all at the same time outside to make it hard (and if there's an event just ask everyone coming).
