To give another deviant a direct link to this FAQ answer, use the following code in your comment or forum post:
My film has some copyrighted images in it, can I still post it?
If you take steps to "blur" the logo's or image in your film, your film submission would be acceptable. Using any work that you do not have a license or rights to, requires written permission to post on deviantARTFilm. This includes, but is not limited to, character designs, logos, music, film and animation clips, and photographs.
All stock resources must also be credited.
Please post information about your licensing in your artists comments.
