I'm guessing both iTunes movies and movies from Vudu app are sent at 24fps? I see this even on SDR content, both with the movie fullscreen and normal aspect ratio.
 
Ok, but was it a HDR or Dolby vision content?
And was it original 1080p content or downscaled 4k to 1125p(xs) or 1242p(xs max).

Not sure if you are asking me? I have seen the issue with iTunes and Vudu content, all streaming only over Wifi. Both movies that are HDR and older that are SDR.

I just played 24p content without stutter. So that’s not the problem.

No sorry, question was for Ritte

Watched another movie in 24p 1080p, no stutter. We can’t find a common denominator here..

Here’s my list:
  • Dolby vision 4K 30fps - no stutter (HW-decoder).
  • Hidden figures 1080p 24fps - stutter (SW-decoder).
  • Hidden figures 1080p 24fps - no stutter (HW-decoder).
  • YouTube HDR 1080p 60fps - no stutter.
  • Coco 1080p 24fps - no stutter (SW-decoder).
  • Reverent 1080p 24fps - no stutter (SW-decoder)

People including me have has stutter with regular SDR 1080p content, as I said. We don’t have any common denominator yet.


And here’s another non-HDR problem:

Definitely not and HDR issue, more of a high nitrate issue: just tried and watch the latest “Better Call Saul” episode on Netflix.

Stuttering made it practically unwatchable.

I want to report the issue to Apple myself: anyone knows how can I talk to someone on the phone, without an AppleCare?
[doublepost=1538077123][/doublepost]Does this work for people? 4K 24fps Dolby vision.

[doublepost=1538077783][/doublepost]Just played the 4K 24fps Dolby Vision file.
With HW-decoding, no stutter. SW caused a stutter.

I now also have stutter on YouTube videos , just the ones that shows as 1080p, not 1080p60 . I guess these are 1080p24 videos.

We can almost guess that most problems arise with 24p content.

What I really can’ t stand, that no reviewers or news sites have noticed this and reported on it, what really makes me wonder if I have one with a hw defect.

Can you link the youtube-movie you had problem with? I think standard youtube is 30fps. 60fps are marked as 60fps.

One of the many examples:

Watch in the YouTube player, seems to be less stutters in default iPhone videoplayer.

 
I get the stutter with this also
[doublepost=1538133584][/doublepost]Maybe we could start a poll, everyone play this video and report stutter or no stutter?

It did not sutter on my Max. But to be honest, that video did not feel smooth even if played on a computer. Probably bad recording.

Can you point out in what timeframe you get the stutter?
 
It’s intermittent for me. Stutters at 1.00 onwards but if I play it again it doesn’t
[doublepost=1538134081][/doublepost]For all we know it might only be 1% of Xs owners who have this issue

I couldn't find any stutter on mine. Does anyone of you have plex? I could invite you to my server and you can test a SDR 1080p movie that stutter for me.

I have the same problem. Sometimes it does, sometimes it doesn’ t stutter.
 
Ok, I don’t get the stutter in YouTube app, but if I play directly from safari it does. That seems significant
 
A colleague played Ozark without stutter, he has a Max. I'll let him try Hidden Figures (SDR 1080p 24fps) that always stutter when I play it with my Max.
[doublepost=1538135330][/doublepost]The colleague that could play Ozark without stutter could not play Hidden Figures (SDR 1080p 24fps) from my Plex Server. It stuttered.

Did he play whole episode of ozark? Because mine was fine for first 10 mins then began stuttering
 
Trouble with this is there are so many variables. Bitrate, resolution, SDR/HDR, the player, frame rate, HW/SW decode, and maybe even what processes are going on in iOS at the time

Yep, we need to find the common denominator here.
 
I’ve just tried the lost in space ep1 scene when he’s in the woods, but this time I hard reset my phone. Played back miles better with hardly any stutter. Then I went into app switcher and quit all apps. Then it was even better
I’m now wondering if it’s some sort of memory management issue
Can people try restart and/or quitting all apps

Closed all apps, still have the problem with stutter.
 
Did you hard restart first
[doublepost=1538142475][/doublepost]Also it doesn’t stutter at the same place each time, if it was a hardware issue surely it would be in same place each time?

No, not if it is a thermal or power management issue.

But I think we can rule out that it is a network/bandwidth issue with streaming, because people have seen the same problems with downloaded content from iTunes or Netflix.

True, but wouldn’t that indicate a software issue that is causing the thermal management issue??
