What does Judder mean?
Judder is a perception of uneven motion, often associated with frame cadence or low temporal sampling. It differs from a complete buffering pause, although viewers sometimes use the same word for several kinds of hesitation.
Why it matters
A slow camera pan makes cadence irregularities easy to see. Source frame rate, output refresh, display response and motion processing all contribute to the final impression. Correct cadence does not make a 24 fpsfilm contain more original motion samples; it only avoids adding an unnecessary uneven presentation pattern. Interpolation can change the look but introduces its own trade-offs.
A practical example
If a pan repeats the same uneven step every time it is replayed while sound remains continuous, examine timing and processing before replacing the router. Report the source frame rate and output mode if available, rather than describing every motion issue as low internet speed.
