What is DAV?

DAV files are built around lossy compression. Designed for surveillance footage conversion, dahua dvr playback, security video archiving, they use the video/x-dahua MIME type and typically range from varies by content.

What is SWF?

Shockwave Flash (SWF) is Adobe's multimedia format for vector animations, interactive content, and web games.

When Should You Use DAV vs SWF?

Best Practices for DAV to SWF Conversion

  • →Test a short clip before converting the entire DAV file — this confirms SWF settings produce acceptable quality
  • →SWF is widely supported but choose bitrate carefully to balance quality and file size
  • →Use constant bitrate (CBR) for streaming delivery and variable bitrate (VBR) for archival storage
  • →Keep the original file in case you need to re-encode with different settings
  • →Check audio sync after conversion — container changes can sometimes cause drift
