The short answer
The effect is motion interpolation, and every brand names it differently: Auto Motion Plus on Samsung, TruMotion on LG, Motionflow on Sony, Intelligent Frame Creation on Panasonic, Action Smoothing or Motion Rate on others. Turn it off for films and drama. Leave a small amount on for live sport if you like it.
Films are shot at 24 frames per second, and that frame rate is a large part of what makes them look like films. A modern TV runs at 60, 120 or more frames per second, so it has to do something with the gap. Motion interpolation invents intermediate frames by guessing what happened between the real ones, producing smooth movement that looks like video rather than cinema.
People describe the result as looking cheap, like a soap opera or a behind-the-scenes video. That reaction is not imagination: the frame rate is genuinely the visual signature of television production rather than film.
Where to find it
- Samsung: Settings, Picture, Expert Settings, Picture Clarity Settings. Turn Picture Clarity off, or set it to Custom with Judder Reduction at zero.
- LG: Settings, Picture, Advanced Settings, Clarity, TruMotion. Set to Off, or Cinematic Movement for a subtle version.
- Sony: Settings, Picture, Motion, Motionflow. Set to Off or True Cinema.
- Panasonic: Picture settings, Intelligent Frame Creation. Set to Off or Min.
- Hisense and TCL: usually under Picture, Motion Enhancement, Motion Clarity or Action Smoothing.
- Philips: Picture, Advanced, Motion, Motion Styles, set to Off or Movie.
The fastest route on any TV is to select Filmmaker Mode or Cinema picture mode, which disables interpolation along with most other processing automatically. If your TV has Filmmaker Mode, using it saves hunting through submenus.
Judder versus interpolation
Turning interpolation off reveals judder, which is the slight stutter on slow camera pans in 24fps content. This is not a fault. It is inherent to the frame rate and visible in cinemas too, and directors compose around it.
Some TVs let you separate the two controls: blur reduction and judder reduction. Setting judder reduction to zero and leaving a small amount of blur reduction gives you a clean film look without introducing the interpolated appearance. This is worth exploring if you find pure 24fps too juddery on a large screen.
When interpolation is actually useful
- Live sport, which is shot at 50 or 60fps and already looks like video. Interpolation here can genuinely help a fast ball stay clear, and many people prefer it on.
- Video game content played back as video, for the same reason.
- Older LCD panels with slow response, where the blur reduction component reduces smearing.
Most TVs keep separate settings per picture mode. Set Cinema or Filmmaker with interpolation off for films, and Standard or Sports with a moderate amount on. Then switching modes switches the behaviour, which is faster than changing the setting each time.
Other processing worth turning off
While you are in the menu, several other features degrade the image on good sources:
- Noise reduction. Designed for poor broadcast signals. On a 4K stream it removes fine detail and film grain, which is part of the image rather than a defect.
- Dynamic contrast or contrast enhancer. Pushes highlights and shadows around scene by scene, causing visible pumping.
- Edge enhancement or sharpness above the midpoint. Creates halos around objects that look like detail from across the room and obviously wrong close up.
- Colour enhancement and vivid modes. Oversaturate skin tones in particular.
- Dynamic tone mapping, which is debatable: on a dim panel it often helps, and on a capable one it departs from the grade.
Setting sharpness to zero or the midpoint depending on the brand, and turning the rest off, produces a noticeably more natural image on any modern source.
Game mode disables most processing to reduce input lag, and that includes interpolation. If you notice the effect only outside gaming, that is why. Do not rely on game mode as your film setting though, since it also disables some processing you want for video.
Getting everyone in the house to accept it
The honest difficulty is that motion smoothing looks brighter and sharper in the first ten seconds, which is precisely why manufacturers enable it by default in showroom modes. Give it a week. Most people who switch to Filmmaker Mode find they cannot go back, and the initial reaction of dull or yellow fades quickly as the eye adapts.
If someone in the household genuinely prefers it, keep two picture modes configured and switch per content. There is no correct answer, only a difference between what the content was made to look like and what some people prefer.
Why do films look like video on my new TV?
Motion interpolation is generating extra frames between the real ones, which raises the apparent frame rate and removes the visual signature of 24fps film. Turning it off restores the cinematic look.
Does turning it off make motion look worse?
It reveals judder on slow pans, which is inherent to 24fps content and visible in cinemas too. Some TVs let you reduce judder without introducing the interpolated look, using separate controls.
Should I turn it off for sport?
Not necessarily. Sport is shot at higher frame rates and already looks like video, so interpolation is less objectionable and can improve clarity on fast motion. Many people leave it on for sport and off for films.
Does motion smoothing add input lag?
Yes, significantly, which is why game mode disables it. For gaming, keep it off regardless of preference.
Is Filmmaker Mode worth using?
It disables interpolation and most other processing in one step and sets the colour temperature the content was graded for. It looks warm at first and is the most accurate preset on most TVs.
The short version
Find your brand’s name for it and turn it off, or simply select Filmmaker Mode, which does that and more in one step. Turn off noise reduction, dynamic contrast and edge enhancement while you are there. Keep a second picture mode with some smoothing for sport if you like it, and give the new look a week before judging.
