Smooth motion

I have the Apple TV 4K 3rd gen. I am unable to remove the soap opera effect. This effect has long been turn off on my actual TV.

Settings﹥Video and Audio﹥Match Content﹥Match Frame Rate﹥On.

That will send a video signal for the same frame rate as the source, without any frame rate conversion or interpolation. It may cause an initial short blank screen while some TVs adjust their HDMI frame rate detection. It should be unnoticeable on higher end modern TVs with Quick Media Switching (QMS) support (requires HDMI 2.1).

We have tried: Accessibility > Motion, then turn on Reduce Motion. No visual changes

That only affects the GUI animations (visually simpler, less fluid transitions/animation during navigation); not video playback.

Once you turn off everything else in Picture->Advanced->Clarity, make sure you also activate the “apply to all inputs.” Now your HDMI picture will match your main TV.

The steps shown above were for the Apple TV box (external TV-connected streaming device), as OP had indicated, which is quite different from the Apple TV app, both for settings and for what it can do.

The Apple TV app on smart TVs is supposed to use the general device video settings. The Apple TV app doesn’t have app-specific video settings (other than the options to limit to SD for low bandwidth users).

The video is absolutely unwatchable as a result.

You’ll have to tweak your TV settings of you didn’t like how app content is shown. This would be similar for any smart app with VOD content. The Apple TV app just decodes 24/25/30 fps streams, same as many other apps. Any ‘smoothing’ or other video post-processing is done by the TV itself, according to its device settings, not done by any content provider app.

I have the same trouble with my 3rd Gen Apple TV on my LG TV. I was getting ready to cancel my subscription. Then I tried a couple more things, and this one worked. I turned off the Auto TV resolution setting: Settings> Audio & Video> TV Resolution> 1280 x 1024 - 60Hz

looks much, much better.

I also changed the HDMI Output setting from Auto to YCbCr. Not sure if that had much of an effect, but it didn’t hurt. Good luck!

Whoops, my bad.

Side-note for those who are having the motion-smoothing effect while using the built-in Apple TV app: It IS your TV causing the "smoothing" but it is fixable. What's funny is, that with my LG 4K TV, if I plainly look at the settings that are applied to all inputs etc, TruMotion & other bizarre settings are shut off. Netflix, Amazon & Crave (Canada) all operate fine. Apple TV app however reverts back to the TruMotion settings. How to shut this off: You must have the video playing with Apple TV as you edit the settings (not when video isn't playing). Literally only saw 1 other forum post with this instruction & it works!

Unfortunately, I'm having the same issue. This is the built-in app for my LG TV. ATV has essentially NO VIDEO SETTINGS at all to tinker with, only what the OP mentioned, which is absolutely useless. The steps Urquhart1244 shows are for a different version of ATV (I assume maybe a separate device connected via HDMI). What an awful app, wow. The video is absolutely unwatchable as a result.
