Why Does Video Lag Happen?

Video lag is affected by frame rate. Frame rate is the number of images displayed per second. The more images displayed per second, the smoother the video. A lower frame rate makes motion look jumpy. Video data in a meeting is compressed before it is sent to the remote side. If the local network or device performance is poor, video lag may occur.

Quick Fixes for Video Lag

When video lag occurs, try the following checks.

​
1. Check Network Conditions

Video meetings require enough bandwidth to stay smooth. Meetings with more participants require more bandwidth. Video clarity is automatically adjusted based on available bandwidth. If the network is poor, DingTalk lowers clarity first to prioritize smoothness. During the meeting, close other apps that consume bandwidth or switch to another network. Recommended bandwidth: To ensure meeting quality, internet packet loss should be below 5%, and latency should be below 100 ms.

​
2. Check Device Status

If memory or CPU load is nearly full, or the device becomes hot, close high-usage apps.

​
3. Check Video Effects

If device performance is poor, enabling beauty effects, virtual backgrounds, or other video effects can increase CPU usage and cause serious lag. Recommended minimum requirements:
