Constant linear velocity or Extended Play discs do not have the "trick play" features of CAV, offering only simple playback on all but the high-end LaserDisc players incorporating a digital frame store. These high-end LaserDisc players could add features not normally available to CLV discs such as variable forward and reverse, and a VCR-like "pause". By gradually slowing down their rotational speed (1,800–600 rpm)[17] CLV encoded discs could store 60 minutes of audio/video per side, or two hours per disc. For films with a run–time less than 120 minutes, this meant they could fit on one disc, lowering the cost of the title and eliminating the distracting exercise of "getting up to change the disc", at least for those who owned a dual-sided player. The vast majority of titles were only available in CLV (a few titles were released partly CLV, partly CAV. For example, a 140-minute movie could fit on two CLV sides and one CAV side, thus allowing for the CAV-only features during the climax of the film).
