What is an AV file?
An .AV file is primarily a security camera video file. These files are created by digital video recorders (DVR) and network video recorders (NVR). Manufacturers like Dahua Technology and Avigilon use this format to save surveillance footage. In a completely different context, the .AV extension is sometimes used for a Final Draft AV Script. This is a document format used by Final Draft for writing dual-column audio-visual scripts.
How to open AV files?
Video-based .AV files usually require specific manufacturer software or versatile media players like VLC Media Player. Because the video encoding can vary between different CCTV systems, standard media players often fail to play the footage. If the file is a Final Draft AV Script, you must use Final Draft to open it. Because .AV has multiple possible meanings, we recommend using viewer.online/av to identify the actual format of your file. viewer.online/av analyzes .AV files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
Best practices and troubleshooting
If you cannot play your .AV surveillance footage, you probably lack the correct video codecs. Sharing CCTV footage with police or insurance companies often requires a standard video format. We recommend using convert.guru to convert your .AV files into sensible target formats like .MP4 or .AVI. If you have an .AV script file, you can print it to .PDF to share it with other users.
Software and tools
To manage .AV video files on a desktop computer, you can use VLC Media Player or official manufacturer tools like the Dahua Smart Player. For script files, you need Final Draft.
Summary
viewer.online/av directly opens and previews .AV files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
