audio track from Wyze security cam is not recorded when exporting the mp4 footage on PremEl 2021

Trying to edit some video recorded by a Wyze security cam.  The video audio plays well on VLC and potplayer but when edited on Premiere Elements the exported video does not contain audio

Can anyone venture a guess what the problem might be that is causing this?

Most likely the security camera is saving video in a delivery format rather than an editable format.

Open some of that video in the free download MediaInfo. In MediaInfo, set View to Text and then copy the text of this report and paste it to this forum. With this more complete info we'll better be able to advise you.

Steve's advice is always very good.   Premiere Elements is made for editing consumer camera footage.  My guess is that it is very likely MediaInfo will show a "special purpose" file structure.  

Consider going direct to a solution of using the (free) program called Handbrake to convert to a more common camera like editable format.   Key words are "H.264", the codec, and "MP4" the file name.

Good luck with your project!

I would definitely recommend a conversion with Handbrake also. I've no idea what an ALAW audio codec is, but I wouldn't be surprised if a number of editing programs don't know what to do with it. You've also got a frame rate of 20 fps, which is pretty non-standard.

Assuming Handbrake can decode that audio codec, these settings should create an editable video.
