Q&A: What to put into movie credits? / legal issues?

Question by Dave: What to put into movie credits? / legal issues?
I’m making a movie and have filmed everyday objects (aka their all in the background while filming or part of the scene) such as name brand soda cans, cars, objects: like tv’s and computers, and have used music by real artists an what not. I image I have to give them credit in the ending credits, how do i go about this and what do I say exactly? Do I “legally” have to call them, tell them I’m making a home movie, and ask for their permission to actually film and publish their products in my film? If so I have to refilm the whole f***** movie.
I’m making this for fun but it will more then likley be going on Youtube and also I’m gonna send it into some film festivals and stuff so its going to be public
I also started the movie off sayin: “the following film is fictional, any similarites to real persons, events, or other films is merely coinicidental and non intentiona;” just so I dont get sued or anything, is there anything else I should be worried about, or do?

Well in the case of everyday objects you don’t have to put anything in the credits but for music it’s a much different story.
If you’re enteringthe film in festivals than you can’t use music by real artists unless you get their permission first by purchasing the rights to use their song in your movie. But you can simply get ‘royalty free’ music in which case you still have to credit the artist but you can ue it in your movie for free. simply search ‘royalty free music’ in google and it will give you a number of good sights that you can choose you’re music based on emotional feel, instrument, and genre.
