How to fix motion judder


Moving images are made from lots of single images (or ‘frames’) shown one after another, measured in 'fps' (frames per second). Most TV programs are recorded at 50fps, but movies are usually filmed at 24fps. More frames per second means less time between frames (for the subject to move), which makes a smoother moving picture. Fewer frames mean more time between images so it might not look as smooth.

Most new TVs have a setting that scans the images as they’re received and adds extra frames to smooth out the picture. Manufacturers often have their own name for it, but you’ll find it in the Picture menu and it usually includes the word “motion”. Sony calls it ‘Motionflow’, on Samsungs it’s ‘Motion Plus’ and on LG TVs you’ll find it under ‘TruMotion’.

The ‘Further Picture Tools’ section of the DVD menu has some video samples that include panning shots to help you find your ideal motion smoothing settings. Some people can find motion smoothing settings a bit odd when they first try them, so start with the lowest setting and increase it slowly.

Motion smoothing works well for some types of content, but not others. It can really improve things like fast-paced sport, but it’s best avoided for gaming.
