Improve quality of a Teams screen-shared video?
erimo This issue was resolved. However, in order to resolve it, we needed to know how networking works in Teams. Here's a great video. https://youtu.be/vi3M7ZzF2NU It's about an hour long, but well worth it.
We put together a few test cases to verify the components of the system we control, specifically, the end points. We did a direct call between computers on the same LAN and attempted to stream the video. Fail. Since this case did not require any communication to the Microsoft Cloud (see the video), we were able to identify that the source computer just didn't have enough horsepower. After switching to a more powerful computer, we could stream video up to 720p without any performance issues. We brought the Microsoft Cloud into the loop by changing from a direct call to a meeting. There was virtually no difference in performance.
In further testing, we found anything less than an i5 would struggle. But as long as you have a decent machine and work within Microsoft's network guidelines, everything seems to run pretty well.
At least that is our experience...
Any news or solutions regarding this issue?

Hi,
Could you specifiy what hardware requirements you were running in comparison to what you upgraded to in order to get this running smoothly? ANd where did your video original from, a video file or on YouTube or something similar?
I was doing some testing with a trainer today who wishes to use Teams for remote sharing video with audio for internal online training for some of our staff members. We were attempting 720p video file then reduced the video quality via HandBrake to 480p and then 360p - 360p much an improvement but still choppy and in my opinion not good enough.
Admittedly, the kit we are using isn't exactly new.. however it is what I would consider recommended specs for Teams under their hardware requirements.
His laptop - i5-6200U, 4GB RAM, 250GB SSD, Intel HD Graphics 4000
My laptop - i7-4770HQ, 16GB RAM, 250GB SSD, Intel Iris Pro 520
No visual improvement over either spec, he shared his videos to me. I shared my videos to him. No different. He was at his house, I was at mine. We both have fibre running a minimum of 40MB/dl and 10MB/up.
Thanks,
Mike
DisputedPond Even using Corei7 10th generation with 32GB memory and electronic HD, problem remains
- Thanks. Are you on Windows or Mac. Does it make a difference though?
erimo I'm on Windows. I don't have any experience on Mac. I don't recall anything that states the Mac client would operate differently, but I tend to gloss over information related to Macs. My memory may be faulty.
There is a Uservoice item (several, actually) that cover this topic. Please vote on this one (or search for one more specific to your video issues): https://microsoftteams.uservoice.com/forums/599053-schools-and-universities/suggestions/41165437-the-quality-of-the-video-of-the-shared-screen-is-b
DisputedPondThanks for sharing. Still, when starting from Brounzer 's original question, it feels like optimising what is essentially a workaround, since it still relies on locally playing a video and sharing your screen + system audio.
Ideally, it should be possible to let a presenter start the streaming of a video straight from a server (MS Stream/Youtube/etc.) to each individual participant. I.e. without the other participants having to click on a link (in the meeting chat) or without having to move to a different window.
Is there any way to do that in Teams meetings now or to get that implemented in the nearby future?
Many thanks.
- Centrally hosted and only relying on download speed. This is what I would have hoped was possible. It doesn't seem to be a widespread approach to synchronize web video, but if we host the video in Microsoft Stream, it would be great if we could share from the server to each attendee, rather than render the video on a machine and present a screen playing the video into the meeting.
