What are the device requirements for high-quality video meetings?

1 min read

Aside from meeting the basic requirements for using Lark (see Hardware Requirements for using Lark), your device should meet the additional requirements below to ensure smooth audio and high-resolution video during meetings.

I. Video meetings

Version: 3.24 and above

For 720p video	Device requirements
		As the meeting host	As a participant
		Clock speed: 2.6 GHz	Clock speed: 2.3 GHz
		Cores: 2 Threads: 4 Memory: 8 GB or above

II. Screen sharing

Version: 3.39 and above

The default resolution of a shared screen is 1920p x 1080p. Device requirements for different frame rates are as follows:

Frame rate	Device requirements			Maximum bandwidth needed
Frame rate		Mac	Windows	Maximum bandwidth needed
15	Memory ≥ 8 GB, CPU cores ≥ 4, clock speed ≥ 2.2 GHz Or Memory ≥ 8 GB, CPU cores ≥ 2, CPU core ratio = 2, clock speed ≥ 2.2 GHz	Memory ≥ 8 GB, CPU cores ≥ 4, clock speed ≥ 2.6 GHz Or Memory ≥ 8 GB, CPU cores ≥ 2, CPU core ratio = 2, clock speed ≥ 2.6 GHz	2 MB
8	Memory ≥ 4 GB, CPU cores ≥ 4, clock speed ≥ 1.6 GHz Or Memory ≥ 4 GB, CPU cores ≥ 2, CPU core ratio = 2, clock speed ≥ 1.6 GHz	Memory ≥ 8 GB, CPU cores ≥ 4, clock speed ≥ 2.6 GHz Or Memory ≥ 8 GB, CPU cores ≥ 2, CPU core ratio = 2, clock speed ≥ 2.6 GHz	1 MB
5	Other	Other	500 KB

When the option "Optimize for video clips" is selected, the video resolution is 1280p x 720p by default. The device requirements for different frame rates are as follows:

Frame rate	Device requirements			Maximum bandwidth needed
Frame rate		Mac	Windows	Maximum bandwidth needed
30	Memory ≥ 8 GB, CPU cores ≥ 4, clock speed ≥ 2.2 GHz Or Memory ≥ 8 GB, CPU cores ≥ 2, CPU core ratio = 2, clock speed ≥ 2.2 GHz	Memory ≥ 8 GB, CPU cores ≥ 4, clock speed ≥ 2.6 GHz Or Memory ≥ 8 GB, CPU cores ≥ 2, CPU core ratio = 2, clock speed ≥ 2.6 GHz	2 MB
15	Memory ≥ 4 GB, CPU cores ≥ 4, clock speed ≥ 1.6 GHz Or Memory ≥ 4 GB, CPU cores ≥ 2, CPU core ratio = 2, clock speed ≥ 1.6 GHz	Memory ≥ 4 GB, CPU cores ≥ 4, clock speed ≥ 2.4 GHz Or Memory ≥ 4 GB, CPU cores ≥ 2, CPU core ratio = 2, clock speed ≥ 2.4 GHz	1 MB
10	Other	Other	500 KB

III. View device configuration

Mac:

Click About This Mac > System Report to view the CPU's speed, number of cores, and memory.

Windows:

Method 1: In Task Manager, go to Performance > CPU to view the base speed, number of cores, and number of logical processors.

Method 2: Use a third-party tool (such as CPU-Z) to view the number of CPU cores and threads.
