Unlike the home video era, films in the new wave are generally of much improved quality, with considerably bigger budgets; averaging between ₦40 million (US$250,000) and ₦120 million ($750,000). These films' production periods take months and even span into years, a far cry from the films in video format which are usually shot in a matter of days or weeks. Other notable improvements in the New Nollywood include: more subtle performances from actors; different from the overt melodrama which constituted the video era, more practical, more logical and generally better stories. Themes explored in these films are often characterized by consciously cosmopolitan themes, as most of the filmmakers are relatively young. A proper copyright and distribution system still remains one of the major challenges in the New Nigerian Cinema.
