Two key innovations in the development of the modern music video were the development of relatively inexpensive and easy-to-use video recording and editing equipment, and the development of visual effects created with techniques such as image compositing.[citation needed] The advent of high-quality color videotape recorders and portable video cameras coincided with the DIY ethos of the new wave era,[citation needed] enabling much pop acts to produce promotional videos quickly and cheaply, in comparison to the relatively high costs of using film. However, as the genre developed, music video directors increasingly turned to 35 mm film as the preferred medium, while others mixed film and video. During the 1980s, music videos had become de rigueur for most recording artists.
