Dear Liu!

I use DVR&NVR ver.5.60

When I convert either to H264 or MP4.avi I dont have any AUDIO embedded in my new files,

My converted files are well playable by most players but I have only VIDEO and no SOUND in them?

What can be wrong, please?

Respectfully

Hi sibirian,

We do not support to convert audio while backup & convert file clip. So you can not get file clip with audio if you convert the format. To get video & audio in file clip, you should never convert the file format.

This was caused by many reason such as, there are too many brands with different audio standard and compression method(NV & DG & Third provider), so please do not convert the format if you need audio, just copy our Player to play the file clip.

Best Regards.
