Frame Grabber CL312H1


AVerMedia CL312H1, the 4Kp30 HDMI 2-channel low profile video capture card, is equipped by four HDMI channels with the embedded audio input and supports astounding uncompressed real-time video capturing up to 4096×2160 30fps resolution.

CL312H1 can improve the quality of a wide range of media recorded for businesses, universities, broadcasting, and manufacturing facilities, which can eventually provide a more lifelike and smooth video playback experience. 

Hardware scaling, de-interlacing, and color space conversion

With the AVerMedia Video Engine Technology inside, it can perform various video processing tasks such as frame rate conversion, hardware up/down scaling, de-interlacing, and so on without consuming the computing power of the target platform.

Improved Quality and Reliability

With the powerful FPGA-based design, the CL312H1 is able to achieve a better performance and provide more improved capture quality and reliability.

Low Profile Form Factor

Suitable for small-footprint embedded platform, the compact low profile form factor design provides a better use of internal space and reduces cable routing. It increases the use of interior space for a more flexible heat spreading solution.

Hardware Video Processing

CL312H1 has built-in AVerMedia Video Engine technology which implements most useful video enhancing features to significantly reduce the efforts of CPU and the software development. In other words, this can help our clients to achieve the better cost saving of the hardware platform and the development resource.

Support up to 4:4:4 10-bit RGB and YUV

The 10-bit color depth support is especially useful in the medical imaging applications where images with the slightest color variation may indicate different conditions or stages of diseases. This in turn may assist doctors in accurately diagnosing patient conditions.
