user35019: I want to ask a question about AMV. 
For example, "Does anyone know who made this AMV ? I cant find who's the author is"

user1458: We already have some amv and we do accept those kinda questions as well as Senshin explains in What is our current stance on questions about peripheral anime topics? 
The question you mention however "Does anyone know who made this AMV? I cant find who's the author is" most likely wouldn't be a good fit.
Amv creators are fans, they often have barely to no online presence, making answering it both hard, and even further disconnected from the "Otaku" culture to the point I doubt its actually even related still.
But it also touches the infamous id-request, which is off-topic.
All together, you can ask questions regarding amv's, but try to stay clear of ID-requests while you are at it.
