heres a link to a very short passage and I extended the crossfade to about a couple of seconds with the audio prominent..

You really only need to see one of these as they can all be exactly the same...

I also did a test... I exported each part as wmv... then reloaded them in and the crossfade then works?

Never had this issue before really?

as you see on this crossfade the sound is correct.

Hi Tony,

What John EB meant was to upload 2 or 3 raw clips from your camera with sound so that we can try them out in MEP ourselves to see if we get the same problem. Also, John can analyze the file, I presume. Maybe you can tape 3 segments of you talking for about 10s each and post the raw files in Dropbox.

Also, which camera are you using?

I just tested out a cross-fade of 2 of my clips in MEP2015 Premium and the sound is fine, nothing like you get. Strange.

I have also uploaded the MTS file (it IS big about 500mb) but it might help further...

audio playing is from about 1/2 way... I did not want to edit this file in any way then that might help with the solution.

it can be pulled down from here:

https://www.dropbox.com/s/z815zahjtqlj4se/00003.MTS?dl=0

This is directly as used from the Camera which is a Sony NEX-FS100E

I have uploaded one from the camera... its big but that way they can hack it easily... the link is on here...

Thanks for the info... hah I figured out how to answer you :)

Lastly I have uploaded two shorter MTS files one 20s and one similar with talking on completely unedited..

Please not e these are still around 77mb

Hi,

I imported your 500 MB 00003.MTS (working on it before you uploaded your smaller files!) and chose an arbitrary point (53:16). There I cut both video and audio tracks.I'm not clear what exactly you meant by applying a cross fade to the audio track. Why would you want to do that with a continuous video, not changing scenes? So I applied a cut-to-black to the video, leaving audio untouched. As expected, there was no sound distortion during that section.

Can you show us a screenshot of your timeline at the point under discussion?

The way I work... is to have a scene (like the one you download)... then I might edit out a mistake (just cut a 10 second bit out (for example). I then slide the piece after the edit to overlap the first part... simple. Ive dont that for YEARS without problem. Now the results are what you see. As soon as you edit the 'joined' overlapped part sounds rubbish - and it was never like that.

Secondly, something is a little telling... if I make the cut from a video - then save each part as a wav... then pake a new video and import the wav files (just exported) then the edit works perfect.

I have always worked that way... check out the 130+ videos on my channel so I see no reason why it should not continue to work.

I have checked every single thing that I can... and 'not editing' the way I do is not really acceptable because it has worked in the past.

The time line is below:

This was one of the test files and you can see on the timeline where the crossfade is..

If you chop a piece out and edit the way I say it should work.

Thanks for the help BTW.

Heres a better one with a bigger time line...

Hi Tony,

I'm using MEP2015 Premium.

I took your 2 files trimmed them to have a smaller output and did a crossfade as you can see below.

The cross-fade starts just after an audible click in the first file and is 2 seconds long where there was no dialog on the first clip except for when you say the word "so." I do not get any noise in the cross-fade like you had in your video. Take a look and listen. I put a title where the cross-fade starts and ends.

There is a lot of background hum and hiss in the clips and you have undoubtedly done some cleaning in your final version. Did you edit the audio and with what and how? Could this be the problem?

It is strange.

FYI heres an example of the same thing (basically) AFTER saving the mts files as waves, reimporting them and crossfading as I described... as you will see its entirely different, but had exactly the same cut and chop carried out to it as the original camera files.

Very interesting.... if you cvan then try it where there is music... it is absolutely far more pronounced when I do that and I had to stop editing at that point. I assume you are using the MTS original file I uploaded?

BTW the 'hum' was from the lighting and amplifier.

I did not use any sofware whatsoever to change the audio in any way. I have only opened the original files to edit with MAGIX Movie Edit Pro 2015 Premium.

I have tried the 'repair' for the software, checked SSD's Hard drives, diabled other startup software etc. and stuff like that but it makes no difference.

I can't duplicate your problem.

About the sound, in your published videos the sound is much clearer than in the test clips you uploaded for us. That is why I mentioned the audio cleaning. With the clips that you uploaded, do you still have the same problem with a cross fade?

If so, then I am afraid that you have a strange problem that we can't replicate. 

If you mix down the audio for each clip and then cross fade them, do you still have the same problem?

Hi John..

The audio is completely untouched and the only thing I have done is to publish the file to WMV format on my har drive. From there I upload. However, the problem is there in the editor before I publish (where the crossfade is) and also after if its there in the editor. When I check the published file the error sounds exactly the same.

What makes things strange is that if the original video is converted to WMV then cooss faded there is no problem!

If I mix them down for each clip (to WMV) then edit them there is no problem. Its only when the file is MTS... which is very strange. If I dont crossfade then there is no problem.

I don't know the answer to this one... how do I get Magix to look at it directly... surely they must have some sort of answer - the camera is completely industry standard and I really don't think it relates to the camera at all.

One thing Ill do is find some other software and try it... if its the same it has to be a flie problem then, but if not it must be a magix issue?

The problem with mixing down each clip as a solution means that it could take a day for each video (some are over 1 1/2 hours long).

Hi

Unfortunately I cannot download the videos at present - 3500 ft up a mountain with an Internet connection that is like good old dialup plus it is snowing ~ 4in /hr and so far we have had to clear the road/paths 3 times.

However following what Terry and JohnCB have done to try to replicate the issue, it does look as though your problem is unique in one sense.

IMHO everything points to the audio codec being used by MEP as the issue.

Have you any of the 'All in one' codec packs installed eg KLite etc?

Do you have any other audio editting software installed?

John

I have found something.... if I select a video section, then create a 'new' frame table, then this stops the video from producing the problem?

I cannot say what Magix is doing when it generates that new frame table.

Clearly going through every video is not really the answer... I need a resolve as to why the MTS files do not work in Magix...

I have escalated this to the magix support and hopefully they will have an answer...

Hi

. . . . I have escalated this to the magix support and hopefully they will have an answer... . . . .

Good idea as the problem cannot be replicated

. . . . . create a 'new' frame table . . . .

Should not have any effect because mts files do not use this technique for synchronising audio to the video whereas mpg files do.

One thought - do you have the Create frametable on import option in the programs settings turned on - if so it is not necessary unless you are using mpg files and could be causing the issue.

Thats OK John I understand... I just wrote this (I guess you saw it)

....  Now I just checked a full length video (indeed the one I referenced on YouTube) and made a new frame table for the video and it solved the audio issue! So I'm thinking you are probably right on this.

I do have Adobe Premier Pro installed (but the problem was there before I installed that) and I also installed the trial of Magix video Pro X..  and I could replicate the exact same issue in the Pro X trial too. So it seems something common to the two - maybe it could conceivably be the video files but I doubt that. More likely the codec which is probably the same for MEP 2015 Premium and Pro X.

I checked this just and alas its turned off....
