Sky F1 UHD / HDR feed stutter

Watching the Grand Prix season opener and the UHD HDR feed stutters continuously. 


Has anyone else experienced this?

 

I have a video of the issue but not sure how to upload.

Whilst it's annoying, my work around does work and it's exactly the same as just tuning into a UHD channel. Just a faff which shouldn't be there. 


You have mentioned previously your workaround, but I am not sure what you mean by  "changing the brightness to HLG". Please could you explain as I would like to give it a go. Many thanks in advance.


Yeah sure thing. So any UHD program or channel I do this:

Settings cog on the Panasonic remote. 
Down to Picture

Select Brightness

HDR Settings

EOTF Type

- Change from Auto to HLG

 

Then return to main settings. 
HDMI Settings

HDR Setting

- Change from Dynamic to off. 

 

Turning the dynamic HDR off stops the flickering or blank screen. However you

miss out on the colours. So changing the brightness to HLG reverts it back to how Sky

output it. 

You just have to change it back when you're done otherwise it looks odd on normal channels. 


That's how I get around it and works fine. Just a pain to do before each UHD HDR content

hi @AlexDavison 

 

If you were watching the replay live when you posted this I can't be sure as I was watching the recording from earlier.

 

I have not had any problems with my recording or when watching F1 UHD Live (05:30 till 7ish) & live since 10am

 

The UHD channels needing more bandwith are more susceptible to slight mis-alignment 

 

If you continue with problems then please see the following page that covers a few problems - if you follow the link through and still have problems then you should find a link to book an engineer if you have your own dish

If you have a communal system you may have to contact your building management to deal with the technicians responsible for the system

If you were experiencing problems I suggest you follow the link I posted regarding signal problems

If your dish is slightly mis-aligned it won't cure itself

Re: Sky F1 UHD / HDR feed stutter

Thank you, I'll check signal strength etc later today

 

It's not a shared dish, and other UHD broadcasts have been ok, so my gut feeling is it's the live feed side causing the issue, rather than my side. 

will certainly check and confirm though!

Zero stutter throughout all the weekend with recorded HLG material, sorry.

@AlexDavison  what make/model tv do you have?

@AlexDavison like @cuke I had no problems with the UHD/HDR for the whole live coverage which would rule out a problem with the feed from the Satellite

 

I am fairly certain that the F1 UHD channel is a different transponder to th eother UHD feeds

Panasonic 55" Z95A oled, on latest firmware with Belkin HDMI 2.1 cable - hope it will be a simple fix! 🤞🏻

Re: Sky F1 UHD / HDR feed stutter

Ah I have the Z90! I have been chatting to Panasonic about it. They say it's a buffering issue with Sky. 

 

@JakeDanzels what's your screen?

 

Itll do that on HDR content but it's random when. If you watch UHD non HDR it's not a problem. 

No idea where the problem lies. I've changed HDMI cables, and it's not the box as it's replicated on a relatives who has a Z90 too.

Re: Sky F1 UHD / HDR feed stutter

I might be able to shed some light on this issue.

 

I have a Panasonic Z95A Oled and since either the January or February firmware update my TV has had a stutter while playing back ANY UHD HDR HLG content from my SKY Q Box. This includes SKY movies, SKY TV programs like House of the Dragon and any APPS when used on the SKY Q box that are in 4K HDR e.g. the latest series of Clarksons Farm. NON HDR content from APPS works fine.

 

I Spoke to Panasonic UK  in mid March and had a visit from their approved service centre that replaced the "Main Board" within the TV.

Starting the TV and following the installation instructions but NOT connecting to a network the TV started up on firmware version RS8112/2363 and ALL HDR content worked perfectly with zero playback issues at all. Problem Fixed? Err no!

Plugging the network cable into the back of the TV immediately triggered a firmware update to version RS8130/3200 (the latest) and the stutter was back. VERY ANNOYING!

 

Two new certified 48GB HDMI cables later and the stutter remains 

I have, fortunately, access to a friends SKY Q box which works faultlessly on his Samsung TV but displays exactly the same stuttering issue on my Z95. My SKY Q box works perfectly on my six year old Panasonic GZ950B HDR OLED TV. It's definitely not the SKY Q box thats at fault.

 

Having spoken to Panasonic UK again, they have now opened an Incident case for this issue for which I am awaiting a reply.

if you are having this problem please ring Panasonic UK Customer Helpline and tell them, although they must be aware of the issue by now.

 

Sorry it's a long post but hope it helps.

Thank you for taking the time to reply.

 

 Very insightful  and will certainly raise this with Panasonic.

Re: Sky F1 UHD / HDR feed stutter

Yeah that's brilliant insight. I have a ticket with them, and they say it's a Sky issue. 

I'll go back to them with this as well. 

I did think it was January or February, but with a lot going on it was hard to notice at the time.
