The next step was to produce one or more masters, a high-quality copy of the finished fansub from which many distribution copies could be made. The fansubber would playback the raw video through a computer equipped with a genlock in order to generate the subtitles and then overlay them on the raw signal. The hardware most often used was an Amiga PC, as most professional genlocks were prohibitively expensive. The final output of the arrangement was then recorded. The master was most often recorded onto S-VHS tape in an attempt to maximize quality, though some fansubbers used the less expensive VHS or Beta. Once it was completed, the master copy was sent to a distributor.
