NoSQL database for storing big files?

If you're going to store binary files in a non-relational database, you could look into using Luwak. You could also look into using Hadoop's HDFS to store your files in a distributed fashion. Neither of these solutions will do much for you until you have three or more servers to run them on and a fast network backbone to support the file replication.

Without knowing more about the rationale for storing large amounts of binary data in a database, it doesn't make much sense. Your filesystem does an amazing job of storing binary files with searchable metadata. If you're just looking to catalog your movies and their metadata, there are better solutions. If you're trying to get distributed and redundant storage for your movies, there are better solutions out there.
