. In the 30 years from the mid-1980s to 2015, tapeless production has moved from being an expensive high-end niche application to being the default workflow for professional production. The availability of low cost disk and high-powered CPUs and GPUs in modern computers has also made it affordable for even amateur productions, and often cheaper than solutions using professional tape formats. It is generally believed that digital tapeless recording is the most robust and easy-to-manage solution for audio and video production. Nevertheless, particularly within the audio world, there has been significant demand for returning to all-

This has not so much been the case with video production, as vintage equipment is often inoperable or unable to work with current technology, and generally lacks the quality achieved by digital video technology.
