What is DAV?

Dahua DAV, proprietary surveillance video format from Dahua DVR systems — stored as video/x-dahua — uses lossy encoding to handle surveillance footage conversion, dahua dvr playback, security video archiving. Typical file sizes: varies by content.

What is MJPEG?

Motion JPEG, video stream of sequential JPEG images — stored as video/x-motion-jpeg — uses lossy encoding to handle security cameras, ip cameras, digital camcorders. Typical file sizes: varies by content.

When Should You Use DAV vs MJPEG?

DAV vs MJPEG: Key Differences

• •DAV uses lossy compression while MJPEG uses lossy compression — both take the same approach to file size management.
• •Neither format changes compression philosophy — both are lossy compression — so any size differences are due to encoding efficiency, not a shift in quality approach.
• •How transparency is handled: MJPEG does not support alpha channels — transparent areas in the source will become opaque.
• •Storage footprint: varies for DAV vs varies for MJPEG.
• •DAV is optimized for surveillance footage conversion, dahua dvr playback, security video archiving while MJPEG is designed for security cameras, ip cameras, digital camcorders — choose based on your specific workflow needs
