What significant development in the 1990's changed video art production?

The availability of video editing software in the 1990s significantly transformed video art production by democratizing the process of creating and manipulating video content. Before this development, video editing was typically a complex and costly process that required significant technical expertise and access to expensive equipment. The introduction of user-friendly and affordable editing software allowed more artists and creators to experiment with video as a medium, fostering creativity and innovation in the art form.

This software enabled artists to easily edit their footage, apply visual effects, and experiment with narrative structures, which in turn expanded the possibilities of storytelling and expression within the medium. As a result, video art began to flourish as a distinctive genre, with artists exploring new techniques and ideas, leading to a rich variety of works that blended video with other art forms.

The other options, while relevant to advancements in video technology and art, did not have the same broad impact on the accessibility and experimentation of video art production during that period. While the introduction of digital audio and high-definition cameras contributed to the quality of video work, it was the integration of approachable editing software that fundamentally changed how artists could engage with the medium as a whole.
