How to convert DAV to MPG
- Add your .DAV file - drop it in the box above or click to browse.
- Convert it to .MPG in a few seconds.
- Download your new .MPG file.
What to expect
- H.264/H.265 is re-encoded to MPEG-2, a lossy step that usually increases file size.
- Any on-frame timestamp or camera-ID overlay stays in the picture.
- Keep the original DAV; re-encoding changes the data and can be challenged for evidence.
Frequently asked questions
Does DAV to MPG lose quality?
Yes, some. DAV's H.264/H.265 video must be re-encoded to the older MPEG-2 codec, which is lossy and typically produces a larger file for similar quality.
Why convert a DAV to MPG?
DAV is Dahua's proprietary CCTV format, while MPG (MPEG-1/2) is extremely widely supported, including on legacy players and DVD-era software. Converting maximises playback compatibility.
Where does the MPG open?
VLC plays MPG on any platform, and most older media software recognises it as well.
What about file size and overlays?
Expect a bigger file and some quality loss from the older codec. Burned-in timestamp and camera-ID overlays remain in the frame, and DAV audio is re-encoded.
