definition of judder:

the term is a sniglet or neologism, a combination of jitter and shudder, and it refers to the quality of 24 frame-per-second film projection to have a shaky, stuttering quality when large objects pan across the screen too quickly [which is anything above a crawl]. it is most noticeable on large projection screens [especially IMAX] but also notable on telecine [movies shown on tv] which introduces a "pulldown" artifact that causes a stutter every 5th frame which makes it look even worse. NTs generally are immune to it [tech reviewer brent butterworth even says he likes it], but i find that i haven't been able to watch a big-screen movie in ages as it gets worse as i have grown older, causing me to get dizzy and nauseous unless i look away.

just in case i am not the only one, there is a solution i've found, and that is to get a tv with a 120-hertz [or faster] refresh rate in combination with anti-judder circuitry, this goes under different names by different manufacturers - S*ny's is called Motion Flow, S*ms*ng's is Movie Plus, Sh*rp's is TrueD, and T*shib*'s is Film Stabilization.

they all work in similar manner, by interpolating extra frames in between the 24 per second of film. most are not without artifacts [subtle ghosting, tearing] but for me the artifacts are much easier on my eyes than the judder ever was.

just wondering. thanx in advance for any replies.

Defintely. I've always felt like 24fps was absurdly slow (as in "how can people stand that?"). Especially in sci-fi movies where they pan across a star field. Looking away or closing my eyes for a bit has worked well enough so far. Not sure if it's getting worse with age, although sensory overloads are in general getting somewhat harder to manage/withstand.

I had no idea new TV's had such circuitry -- good to know.
