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...
Brounzer We have a similar issue. Our customer wants to perform new employee training using Teams Meetings to multiple regional sites. All the desktop specs in Task Manager seem to be OK (although the network bandwidth seems to flatline at 2 Mbps), and the Call Analytics in Teams show good quality connections. The customer is willing to pay for better hardware, but I can't seem to determine which part of the system is the bottleneck. I have had some success in reducing the resolution of the videos down to about 360p, but something doesn't feel right about that solution. It seems like we just need a little more insight into how Teams is handling the shared desktop apps.
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
