Distorted Audio when played in editor and exported

Hi,

I am using Magix Movie Edit Pro 2015 and when I import my video clip (.mp4) the audio from the clip can be heard but the program seems to add distortion that sounds like crackling and every few seconds the crackling peeks and becomes very loud. The audio sounds perfectly fine in windows media player. I have used other mp4's before and the problem that I think is happening is with the bitrate of the audio because it is the only thing changing. My one recording device that works uses 126kbps while the other that doesn't work uses 192kbps. Is Move Edit Pro incomplatible with 192kbps? or is there another problem I am overlooking?

Bitrate should not affect the audio import, however there are two possibilites:

The samplerate is out of the accepted range for MEP ie audio at 48, 44.1, 32, 22.05 or 11.025 kHz - are acceptable with 48kHz being the preferred option.

OR
When you seperate the video and audio on to seperate tracks and create the waveform it look like this

If so try enabling the audio setting shown below and import the video again into a new project.

the file is 48kHz and the audio setting did nothing. There are spikes in the audio causing the noise like shown in that picture but they are not in the original file

. . . . There are spikes in the audio causing the noise like shown in that picture but they are not in the original file . . . .

Occasional spikes are OK, however are you getting flat tops as shown in the image below?

Can you post a screen shot of a section of the audio?

This is the first two or so minutes and it happens throughout the entire clip

I created a 20 second clip to demonstrate. the first video is no program just straight from the recording software. The second video is the same clip being brought into MEP and rendered.

Thanks for the screenshot and the videos - the problem is very clear however it does appear that the clicking is to some extent random.

Can upload the original from below to somewhere like Dropbox and post a link for us to test - don't post to Vimeo, Youtube or any such sites, they convert the video which is not what we want.

Thanks
