The purpose of the revised Convention is to provide a legal and financial framework for the co-production of feature-length films involving production companies established in three or more states Parties. The revised Convention can also be used as a bilateral framework in the absence of a specific co-production treaty between two Parties. The participation of one or more co-producers who are not established in such Parties is possible, provided that their total contribution does not exceed 30% of the total cost of the production. The co-produced work must also meet the definition of an officially co-produced cinematographic work set forth in Appendix II to the Convention.
