What is a CAVS file?

The CAVS (Chinese Audio Video Standard) file format is a digital video compression standard developed by the Audio Video Coding Standard (AVS) Working Group of China to compete with H.264/AVC and MPEG-4. Officially known as GB/T 20090, this format utilizes 8x8 integer transformation and motion compensation similar to MPEG standards but with lower computational complexity, designed specifically for High-Definition (HD) digital broadcasting and IPTV services within China. It serves as the national standard for source coding, reducing reliance on foreign intellectual property licensing fees associated with international codecs.

How to open a CAVS file

Because CAVS is a regional standard specific to the Chinese broadcast ecosystem, native playback support on Western operating systems (Windows, macOS) is nonexistent. To view these files, users require a media player capable of utilizing the libavcodec library, such as VLC Media Player or FFmpeg-based tools, which include specific decoders for AVS1-P2 and AVS+ video streams.

What is a MOV file?

The MOV filename extension represents the QuickTime File Format (QTFF), a proprietary multimedia container developed by Apple Inc. It serves as the structural basis for the ISO/IEC 14496-14 (MPEG-4 Part 14) standard. The format utilizes an atom-based structure where data is organized into hierarchical units, allowing it to contain multiple tracks of video, audio, timecode, and text (subtitles). Common codecs encapsulated within MOV containers include Apple ProRes, H.264, and HEVC for video, and ALAC or AAC for audio. It is the default recording format for iPhones and iPads.

How to open a MOV file

MOV files are the native format for macOS and open directly in QuickTime Player. On Windows, native support is available in modern versions of Windows Media Player, though legacy support relied on the now-deprecated QuickTime for Windows. For cross-platform compatibility and to handle professional codecs like ProRes on non-Apple systems, VLC Media Player or Adobe Premiere Pro are the recommended tools.
