Video and Audio out of sync?
MicrosoftI'm having a similar issue. I uploaded a 3 minute mp4 that got compressed by about 15 seconds. The audio and video fall out of sync almost immediately. I double-checked the mp4 and it's exactly what I wanted, so it seems that something is getting compressed or edited on upload to Stream.
MicrosoftI'm guessing there is an issue with your source video file in terms of encoding. It's possible the player you are using locally can handle the anomaly but I bet not all players (including Stream can't). Can you try encoding your video again? Where did you export it from?

The video was recorded using the Windows 10 camera app.
If I download the file, the audio/video is synced properly.

No luck. My 2 video tests from the Win10 camera app didn't have any audio/video sync issues. If you want to open a support issue and send them a copy of the MP4 with the issue, they can get it to us to run encoding / debugging.
Or if you want to send it directly to me I might be able to find time to have someone look at it.

Trying my own 3 min video from the Win 10 camera app, I'll see if I can reproduce your issue. If not, then I might need you to send me your video so I can have engineers run it through encoding again to debug.
