Microsoft Teams Video Lags on Microsoft Teams for Mac app

New Contributor

Hello Everyone,


I'm using an M1 Macbook Air and I have a Lenovo FHD webcam that is connected to the laptop via a dock. When I try video calls with the Teams Mac app the video appears laggy, almost like I'm in slow motion. Oddly enough, the video appears fine when testing it out in FaceTime and Microsoft Teams online on the same computer. Anybody run in to this in the past?

@jmmsas I am having the same issue.  Camera works fine in Zoom as well however in TEAMS all of a sudden I am in slow motion.  Weird thing is this same camera worked fine in TEAMS two weeks ago.  This just started.

@Matthew_Koenig This is a known bug. Most of external webcams behave like this. This is because of MS Teams is still no native M1 app but runs in Rosetta 2. Blame Microsoft for not getting this done in time...

Same here...worked at the end of December and then stopped. I used another lower resolution 720 webcam and it works fine. It seems to be challenged by higher definition webcams.

@jmmsas I am having the exact same issue and the M1 point doesnt totally make sense as it worked fine in early Dec while I was using an M1 mac.  Any help would be greatly appreciated.



@hughwellman It is not just an M1 problem. I can confirm this. I have a 2019 16" almost maxed out (i9, 32GB Ram, 8GB Video, 2TB) which is why I didn't upgrade to the M1, still waiting on M1 Max to get here. 

Starting recently video is choppy. I found that if I open a secondary app that uses the camera, like OBS, the video gets smooth, even if I don't switch the device input to OBS cam.

@jmmsas Just so all you wonderful M1 owners don't feel too special, I am experiencing this on a 2019 MacBook Pro with Intel chip. I didn't experience it prior to an update in the past two months or so--I didn't watch closely when it started.

I have also started experiencing this issue on my M1 Macbook Air over the last week -- no problems prior to this -- and only teams is impacted. I have tried switching hubs/docking stations and tried plugging directly into the machine.


Also, I had tried clearing the MS Teams cache and reinstalling the application.
