Is the level of HD video support in the conference 1080p?
The default is 720p, and the highest support is 1080p. 1080p requires relatively high system hardware and bandwidth. The camera of the client device needs to support 1080p, the CPU must be at least 4 cores, and each channel of bandwidth needs 3 ~ 4M (uplink/downlink).
What factors are related to the video clarity in the meeting?
Participants' bandwidth and network stability;
Server bandwidth and network stability.
The video control in the meeting adopts "adaptive" mode. When the network condition is good, the resolution of the sent video is high; when the network condition is poor, priority is given to ensuring audio transmission and appropriately reducing the quality of the video.
How to get better video effects?
Please ensure that the public network bandwidth of each participant is sufficient (each participant>0.6Mbps);
Please purchase a camera that supports 720p HD calling and autofocus;
Try to use wired connection to the network, if you use WIFI, please ensure good WIFI signal strength;
If you see that your video is blurry, and the camera does not support auto focus, please manually adjust the position of the camera and ensure that there is sufficient light;
To ensure sufficient power and memory for mobile phones and tablets, please try to close other programs;
Please make sure that the notebook is in "best performance mode", not "most power saving mode".
The image of the camera appears blurred, black or white
Check the driver installation and possible device conflicts;
Check whether the camera model matches the camera driver;
Change the graphics card to test, because the camera may not be compatible with the graphics card or the display driver;
The camera and the graphics card are most prone to conflicts. When there is a problem, in addition to looking for the camera itself, you must also check the graphics card and try to reduce the speed of the graphics card. The method is: single-click the right mouse button on the desktop, select "Properties→Settings→Performance", and gradually reduce the hardware acceleration from the fourth gear to the last gear to see if the problem can be solved. If you can, gradually upgrade the grade until you find the balance point that can solve the problem.
Why do some users have poor video images?
This is caused by the strategy logic of receiving and sending. The sending end often requires more CPU resources. Therefore, for users with poor device performance, the resolution of the image sent is often smaller than the resolution of the received image.
The client has checked
The camera is forced to collect 720p video and send 720p video out, but the video that the recipient sees is related to its bandwidth, video screen layout, and whether it is full screen, not necessarily 720p.
Can a camera with HDMI interface be used as a camera with Umeet?
The HDMI of the computer is for output and cannot be used as an input signal. Must pass one of the following methods:
Video capture card with HDMI interface;
USB interface connection;
Does the video conference support video capture card?
Generally, popular capture cards on the market are supported.
Windows or the camera is not listed in Umeet
Please select the correct camera in the settings of the Umeet client;
Please check if the camera is occupied by other programs, such as WeChat, Dingding, QQ, etc., exit these programs and try again;
Please change a USB port to connect the camera (some USB ports have too low power supply);
Please make sure the camera is connected and turned on;
Please try to restart the computer and try again;
Please reinstall the camera driver and restart the Umeet client.
