many movie enthusiasts prefer pal over ntsc despite the former's speed-up, because the latter results in telecine judder, a visual distortion not present in pal sped-up video. states ""the majority of authorities on the subject favour pal over ntsc for dvd playback quality"". also dvd reviewers often make mention of this cause. for example, in his pal vs. ntsc article, the founder of michaeldvd says: ""personally, i find [3:2 pulldown] all but intolerable and find it very hard to watch a movie on an ntsc dvd because of it."" in the dvd review of "frequency", one of his reviewers mentions: ""because of the 3:2 pull-down artefacts that are associated with the ntsc format (…) i prefer pal pretty much any day of the week"". this is not an issue on modern upconverting dvd players and personal computers, as they play back 23.97 frame/s–encoded video at its true frame rate, without 3:2 pulldown.
