Video stopped playing after 30 mins while sharing screen. Had to quit Zoom and share again.

I am using MacBook bro and desktop app of Zoom with latest version. Yesterday I faced a peculiar issue. While sharing a HD video (through advance sharing option), it suddenly stopped. 

Took the following steps however didn't resolve the issue:

1. Unshared the screen and shared screen (screen went black)

2. Started the video again.

Lastly, I quit the zoom application and started the app again and it solved the problem.

Question:

1. Is there is a limitation on length of video which can be shared using zoom share feature.

2. Is there a limitation on size of the video which can be shared using zoom share feature.

Thanks for help.
