Chugging Sound

[ianm52471878]

Recently I bought a Browning Spec Ops Edge Model BTC-8E  wildlife camera, which records videos on MP4 format. When I edit videos from it using APE 11 I hear a repetitive "chugging" sound at 3 or 4 beats per second that wasn't on the original video. The Browning's the fourth trail camera I've owned but the only one where I've encountered this phenomenon when using APE.

Has anyone else had this problem, please, and if so is there a solution?

>MP4 format

MP4 is a wrapper, what is inside YOUR wrapper - Exactly what is INSIDE the video you are editing?
Report back with the codec details of your file, use the program below

Many thanks for your reply. I followed the link and installed MediaInfo, but so limited is my techy knowledge that I understand as much about codecs and TREE as the average pet dog does. I think I'll just have to reduce the volume on the APE audio track and carry on regardless; either that or use different movie-editing software.

Thanks again,

Ian

I wouldn't give up so easy, ian. If you can give us the MediaInfo report, we can likely figure out what's going on and what to do about it.

Just open your original video in MediaInfo, then set the program's View menu to Text. Copy this text and paste it to this forum. We'll take it from there.

Thanks, Steve.

Is this the information that's needed?

I think I may have stumbled across the solution to the problem. Firstly, the repetitive sound that occurs when I upload videos from the Browning camera to APE 11 is actually the intial sound of the clip being repeated several times per second throughout the clip. I don't know why this occurs, but the solution seems to be to pass the clip through a video convertor - I used HD Video Convertor Factory - before uploading it to APE 11. The repetitive sound doesn't then appear on the APE 11 version.
