I've been using Zoom for many years to teach my classes. I've never had a problem like this. Yesterday, during a class, I shared (tried to share) a video that was over 90 minutes long in Full HD, with a file larger than 10GB, using the option to share a locally stored video file.
After about 70 minutes, the video playback froze. I stopped sharing and restarted it, but the screen remained black; the video wouldn't "load." I ended up using the video directly on YouTube, losing contact with the students.
I used a 14-inch MacBook Pro (2021) with an M1 Pro chip, 16GB of memory, and macOS Tahoe.
I have new classes via Zoom and will have to use this material again.
Does Zoom support this type of sharing or not? What's the best way to present this video in the next class? What should I do?

    hi ​@Silvana Occhialini 

    That is a large file, even for 90 minutes that is very large.
    with respect you are using an older Mac and I would suggest you use a tool to make the video smaller first.
    That size would also be putting pressure on your internet connection and any short term loss could have caused this poroblem.

    Personally, I use a program called handbrake and I know it is available on the Apple App Store.
    You would not see a loss in quality for your meeting.

    Please like and mark as the solution if this helps

    All the best
