When the camera pans and the picture stutters, like it's low FPS. What is that effect called and how to fix it?

by notwillienelson

I had this on all tvs I've ever owned. More pronounced on some. Also depends somewhat on source material.

It's always when the camera pans over scenery ... Like a view from a chopper. Or a 360 showing surrounding area. Or the pan over the snowy mountains in LOTR.

The picture sort of stutters, cuts, becomes jerky, like it's half way stuck, and instead of a fluid movent of the picture, you get chop chop chop, with what feels like 5 frames Per second.

What is this called , and what settings can be played with to fix it, if any ?

I've seen this on TVs with Motion Smoothing enabled.

Turn it off and see what happens.

It's because the frame rate of the display doesn't match the frame rate of the source material. Some Android TVs can change resolution on the fly. Some apps make use of this feature.

For example, if your content is 60 fps, playing it on a 50 fps display means dropping every 6 frame, leading to a jerk every 100 milliseconds.

You should look for a setting that mentions "automatic refresh rate switching" or anything similar in your media player. Plex and Kodi already have this feature.

Basically, when a source file is encoded at 24 fps and you're watching it on a TV with a 60Hz refresh rate, the picture would appear with judder (which you observed in panning shots). To play the source file smoothly, the player needs to match the frame rate of the TV to that of the source file.
