Limit single video/pic 2 certain membership level?

i want to know if there is a way to limit single video/picture or module post to certain membership level instead of whole module limitation.

the only current way to do it is put your content in a page block on the page you want then use page access control for limits on that block.

As far as I know anyway... 

As dolphin_jay mentioned you can use "Page access control" module, but instead of page blocks you can also restrict access to single video/photo by url.

Thanks. I asked it cause l want to make 2 membership levels

1. Under 18

2. Above 18

So I can restrict any adult/graphical content to only Above 18 membership level. Problem solved but I think there will be too much manual work in dealing this kind of issue.
