Teams video quality

We have been holding off on switching from Skype for Business to Teams for our videoconferencing and telehealth due to the poor video quality. I tested it again today and noticed that if I sign completely out of Skype for Business, the Teams meeting audio quality improves, but not the video. Would the video improve if we completed the upgrade switch to Teams?

Thank you for your valued time in responding.

Thanks All. I got a response from Microsoft Teams Support:

Microsoft has reduced their bandwidth and quality settings to 720p or less in some cases with the surge of usage due to corona virus. Until they upgrade to meet demand or people go back to normal life we won't be able to really get solid video through the service for a bit

Hi,

I've personally not had video quality problems, but there are currently many reporting video quality issues.
This is most likely due to the awareness of Microsoft 365 temporary feature adjustments" due to very extensive increase in the cloud services during the pandemic.

From what I've read today, Microsoft are as increasing the capacity as we speak due to the high demands.

You'll also of course need to ensure you meet the hardware requirements:

Best regards,

Thanks, Leon. All of our company issued user devices exceed the hardware requirements,
I'm hoping to receive a response from Microsoft with a date for the increase in video quality so I can finish up and move on to other projects. We've been in this holding pattern of the upgrade since March. Our company has been phasing back-to-the-office this month. The best time to increase video quality for telehealth would have been earlier in the pandemic. Thank you so much for your advice.

Hey LindaJohnson-3599,

I would recommend 2 things that are not technical related if you have solid hardware on your endpoints already.

1) get with your Microsoft account team and ask them to put you in touch with other customers that have deployed Teams for the purpose of Telehealth. They can get you in contact with another custom and collaborate on how they got it setup and any technical configuration changes they needed to make

2) get with your TAM (technical account manager) with your premier support contract if you have one, if not then use some of your software assurance premier incident credits > all to ask for an O365 Network performance assessment engagement. This is an incredibly detailed assessment of your path to O365 and back from a maximum of 6 laptops (that you can put anywhere in your network). These laptops will run synthetic transactions with an account you stand up and license for the duration of the engagement. After a couple weeks of running the laptops you will work with the PFE (premier field engineer) to upload the data from each computer > then go through a very detailed analysis. They look at EVERYTHING down to the packet level. We are awaiting our analysis as I type.

Hope this helps!
Jason

Thank you Jason.

We do have a couple of Microsoft Gold Partners I can reach out to. Thank you for the recommendations.

Hi LindaJohnson-3599!

I found many customers have the same issue in Microsoft Teams.
https://microsoftteams.uservoice.com/forums/555103-public/suggestions/19096657-webcam-quality-is-very-low

In my understanding, we recommend you check if your bandwidth is sufficient. Teams is designed to give the best audio, video, and content sharing experience regardless of your network conditions. That said, when bandwidth is insufficient, Teams prioritizes audio quality over video quality. The following table shows how Teams use bandwidth for your reference:

Thank you Jimmy.

Thank you for the link. The question reads like it could have come from us. We also have fiber optic internet.

I understand that Skype for Business and Teams are different applications but I'm confused as to why SfB video on the same network would be sharp, and clear with good clarity and quality and Teams is fuzzy and unclear. Is it poor Teams application? I'm a huge fan of Microsoft. I don't want to believe it could it be that the Lync developers could provided a better application.

Are you able to provide the same bandwidth scenarios for Skype for Business for comparison?

Do you have any details on Bandwidth values for Teams-PSTN Calls.

I answered my own question.
SfB network-requirements



The bandwidth numbers you provided are the same for Skype for Business.

So, in conclusion our bandwidth is not the issue with the poor video quality with Teams. I did include myself in the user voice for Teams. Thank you guys so much for your thoughts, ideas and support. :)

Hi LindaJohnson-3599!

You can also try to consider other factors like packet loss and jitter. Microsoft Teams provide Dashboard to analyze it, you can refer to:

We see that they lower the quality in our meetings, genarally with +30 users meetings. This info can be found in the report checking the report for the meeting, and checking the user report:

38889-mskvalite.png


So in above the enduser sent 720p into the server, but the server lowers it to 360p WITHOUT notifiying us of it.... So they are trying to hide this, they should push an notification to the meeting as a banner with info like:

We Microsoft have lowered the quality of the video stream for user XXXXXX due to Covid-19.
But i guess they dont want to inform user of this, as it means you pay for a service that they do not deliver.
