Lip Sync Issue in Zoom during running a Pre-Recorded Video PPT



During a Zoom Meeting , we have experienced a Lip Sync issue with a pre-recorded video . The host is sharing the screen and running the video while others are listening .  It was initially  through that the Host may have some network issue . But Laster on , we have done trial with Same Video sharing with Different locations with different service providers broadband and  almost everytime we have experienced the same lip-sync issue.  For each testing broadband speed was between 60 Mbps - 300 Mbps , which is much more that Zooms video requirement .

The Problem Pattern was not very similar in all trials.  Sometime the problem starts after 5 minutes. Sometime after 2 minutes. 

Can anyone share some lights on this. We have done testing with same Video-PPT every time to reduce variable. 



Latency is an inherent problem in remote meetings and all kinds of online communication. The only remedy is to get a faster connection, which reduces, but doesn't eliminate, the problem.

Hi Jameswalter


First of all thanks for the reply .  But if you gone through my Post ,  You will notice that , we have tried to share this video , from different Internet with different service Provider , but having the same issue.   As per the Bandwidth is concerned , we have tested with Bandwidth from 60 Mbps - 300 Mbps ( As per Official Zoom site Max Bandwidth require for 1080P  is only 3 Mbps , so we have minimum 20 times bandwidth available ) . Also the Latency is from 200 - 250 Mbps  to Zoom USA  which is I think is acceptable for us. 


The lip-sync problem happens only time when when we are trying to run The PPT with Video . There was no issue observed during normal meeting .
