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:| Client | Maximum Video Resolution | Maximum Frame Rate | Recommended Bandwidth |
|---|---|---|---|
| Mobile video | 720p | 15 fps | 1.5 Mbps |
| Mobile sharing | 1080p | 5 fps | 1.5 Mbps |
| Desktop video | 1080p | 15 fps | 2 Mbps |
| Desktop sharing | 1080p | 5 fps | 1.5 Mbps |
| Hardware meeting terminal | 1080p | 15 fps | 2 Mbps |
| Hardware meeting terminal sharing | 1080p | 5 fps | 1.5 Mbps |
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:| Video Effect | Windows Device | Mac Device |
|---|---|---|
| Basic beauty effects, video noise reduction, dark-scene enhancement | Intel Core i5 or above, Intel Skylake or newer, AMD Zen or newer, 4+ CPU cores, AVX2 support | Mac models from 2014 or later, 4+ CPU cores, AVX2 support |
| Virtual background and advanced beauty effects | Intel Core i5 10th generation or newer, Intel Willow Cove or newer, AMD Zen 3 or newer, 6+ CPU cores | Mac models from 2019 or later, 6+ CPU cores |
