About format

CAVS (Chinese Audio Video Standard) is a video compression standard developed by the Audio Video Coding Standard Workgroup of China and adopted as a national standard (GB/T 20090.2) in February 2006. The project began in 2002 with the aim of creating an independent compression technology that could serve the massive broadcasting and multimedia infrastructure in China without relying on foreign-licensed codecs. CAVS, also referred to as AVS1, achieves compression efficiency comparable to H.264/AVC while utilizing a simpler patent framework with significantly lower licensing costs. The standard supports video resolutions from standard definition up to high definition, making it suitable for both terrestrial digital television broadcasting and broadband streaming. Key technical features include 8x8 block transforms, multiple prediction modes, and a loop filter designed to reduce blocking artifacts at low bit rates. The Chinese government endorsed CAVS as the mandatory compression standard for the national digital TV broadcasting system, ensuring broad deployment across set-top boxes and television receivers in the country. While CAVS has limited international adoption compared to H.264 or HEVC, its significance lies in serving one of the largest media markets in the world and demonstrating a viable national alternative to globally dominant video coding standards.
Initial release: February 2006

Frequently Asked Questions

Why convert CAVS to another video format?

CAVS is a Chinese video standard with limited global support. Converting to a widely used codec like HEVC or wrapping in MP4 ensures playback on any device.

What programs play CAVS natively?

Specialized Chinese media players and some builds of VLC with AVS decoding support can play CAVS. Outside those, converting is the most reliable approach.

Will conversion from CAVS lose quality?

Selecting a high-quality target codec like HEVC or AV1 at a matching bitrate preserves visual fidelity. The output can look virtually identical to the original.

Can I convert multiple CAVS clips in one go?

Yes. Upload a batch of CAVS files on convertio.tools, set individual output formats, and process them all simultaneously to save time.

Is CAVS conversion free at Convertio?

Everyday conversions are free. For larger uploads or high-volume needs, Convertio offers premium plans with extended capabilities.
