Netflix movie frame stutter with Apple TV 4K

[colinw123]

Hi,

For some time now if i watch any movies on Netflix using my Apple TV 4K i get the odd frame stutter throughout the film.

TV Shows are fine and silky smooth, it only seems to happen to the films.

I have frame rate set to enabled, and dynamic range set to disabled as i don't like HDR, so watch the 4k Netflix content in SDR.

Any ideas why this is happening at all please.


Thanks.

I believe this is because some of the original Netflix productions are shot at true 24.000 frames per second as opposed to the more common 23.976 frames per second that most movies and basically all tv shows are shot at. The Apple TV currently doesn’t support 24.000 fps. When the Apple TV is in 24p mode it is actually in 23.976p mode.

edit: Lots of info on this here:

[fixed!] Apple TV 4K lacks support for 24.000 video

//EDIT 26th April 2021: I still cant believe what I'm writing as I have given up hope. I guess cows are flying and hell is frozen over now. With iOS 14.5 Apple has finally added integer frame rates such as 24.000 and 60.000. The below behaviour does not apply anymore. I recently got an ATV 4K...

That's correct. Though some TV's can compensate for that. On my LG OLED I don't see any stutter in that content while others do.

I do see stutter on my LG OLED B7. But I have deactivated every kind of image altering function on the LG. I’m currently letting the ATV switch frame rates based on the source material but I’m finding the LG extremely slow and buggy at switching frame rates.

I have tried setting the Apple TV to always output at 60p and turned on the correct settings on the LG to let it detect and adjust for 24p over 60p. It looks mostly fine, but every once in a while I feel as though the LG makes a mistake and I get a short moment of soap opera effect or stuttering.

I don’t find the function to be 100% reliable and so I’m stuck letting the Apple TV send the native frame rate to the LG and waiting several seconds for the TV to switch. Quite often something goes wrong and the LG hangs and shows the “no input” screen saver thingy. Then, after several more seconds it finds the signal again. I use the Apple recommended high speed Belkin HDMI cables.

There is a setting related to motion that will fix that. I don't recall the name off the top of my head or what I have it set to. I'd have to look when I get home. But it fixes all motion related issues without introducing the soap opera effect. I have the B6.

I got to admit I've enjoyed the ATV discussions on AV/AVSForums and read about this just today.
Any reason why Apple still have not implemented this 24fps auto detection?

And please Apple give iTunes films Dolby True HD. I'm really fed up of iTunes low volume, dull sound quality on films. It's a shame when YouTube vlogs sound more punchy and alive than what Apple still offers.

Hello I'm UK based . Just purchased the apple 4k..it had the Netflix stutter I have my TV set to SDR as you should with a 4 k TV using the Apple TV, I fixed the stutter by signing into my Netflix account on PC and in settings changed the quality of download from auto to high, then signed out of the Netflix app on the Apple TV and signed back in ..no stutter.

Sorry only just seen your message, ok thanks I’ll give that a go but I think it’s just that some films run at 24p as apposed to 23.976p that all.

thanks again.
