VideoWave audio distorts after splitting track

[jimandmelea]

Hello

    Being trapped away from my home computer, I had to purchase another Roxio NXT 7 for my laptop to get work done.  I'll include snips of the laptops specs (windows 10 64 bit, dell inspiroin 3000) 

I've been using videowave without hangs or freezes, however, I just now made a cut and removed the clip in the middle.  I put a 3 sec fade on the new clip and now it distorts and sounds mangled and digitized.   I right clicked edit native audio, and selected a portion.  When I click PLAY it plays fine. (without cleaning or making any changes)  When I X out of audio editor, and press PLAY on edit workspace line; it distorts mangled and digitized. 
I just extracted audio from source file, as my job requires me to produce an audio only podcast version and a video.  The audio file is fine.  
I converted the original video.mp4 to wmv720, deleted the orig video, and upon re-opening videowave project, re-located the editor to the new converted wmv720file.   It still distorts.  

I think it's a problem with mp4's.   If u read my past posts using NXT 7, using NXT 7 on a new desktop; I had similar problems with audio.   Whatever happens, seems to corrupt the audio half way through... like anything over 20 minutes... it just starts distorting.   

I just got an email from a guy who I produced 10 videos for combining pro audio mp3's with still jpgs.  He said there's a problem.  I checked those videos,and sure enough...  half way through.. it distorts the audio.   Listen for yourself.   https://www.dropbox.com/s/s0xmc1bwn9zrcty/Solo_BellaDePaulo_2.wmv?dl=0

Please advise.

I actually edit the raw WAV audio, and send it to apple itunes.  I pulled the peter mcgraw audio  from the Itunes store.  They all play fine.  Even in roxio, at first they play fine...  all it takes is a few cuts edits, and the audio becomes distorted.   Today I imported a WAV file to replace the native audio, and it did the same to the wav audio.    Whether i render to AVC, mpg, mp4 or wmv;  this phenomena reoccurs intermittently.

Protected content or not?

Could it be DRM Digital Rights Management?

Is doing what you are doing a violation of the Apple Store user agreement?

From where?

[jimandmelea]

I receive the raw WAVs recorded on a zoom digital field recorder.  I then edit, optimize, and export the mp3.   The WAV I imported was my own export.  I can also tell u, that I have pulled down/ downloaded mp3 audio from www.petermcgraw.org and have experienced the same phenomena.  

I'll have to research copyright protection via file corruption.  I remember in the Kazaa days, that was a thing.  
fyi   I"m using Roxio NXT 3 on my old laptop.  No corruption distortion issues.

Roxio just needs to fix this bug.  It has existed for years.

This appears to be the same problem I experience with NXT6.  I have spent MONTHS with tech support.  All of their suggestions are WORTHLESS.  I even created screen captures to prove what is going on.  They (tech support) continually feign ignorance to attempt to close the inquiry number.  Interestingly, I finally came across one tech who mentioned this is a common complaint.

Here is what I discovered - for whatever reason when the program creates the audio proxy file, it creates a “corrupted” proxy audio file.  The longer the video to be edited, the more fuzzy/corrupt the sound will progressively become.  It is clearly a problem with how the program extracts audio from the video when it creates the proxy file.  They may have hard coded an improper setting into the program or something.  You can confirm this yourself by changing the default audio proxy directory in settings and then listening to the audio file it creates.   I can’t figure out if the program uses the proxy file for rendering or if it creates another temporary (yet also corrupt) audio file.

 This is repeatable on multiple machines.  An i9 - MacBook running windows duel boot - even my surface 4.   All of them exhibit this behavior.  I believe they use ffmpeg to extract, but I still don't know how it is called up for the conversation.

This is entirely due to a poorly crafted program.  I can replicate the problem with multiple machines and differing files.

It is not your drivers (video or sound) - it is NOT a machine dependent problem.  It is a bug that Roxio/Corel must address.

I was hoping a fix would be issued by Roxio/Corel to take care of it.

Contact tech support via email in this site.  Let them log a complaint.   https://www.roxio.com/en/support/

Here is how you can confirm you are experiencing the same bug:

1) Change the Proxy Files location to an easy to get to folder so you can detect when the proxy files have completed rendering.

2) I delete all proxy files.

3) When a video file is first loaded - playback is fine.  (Rendering at this point will result in corrupt audio in the final result because they use the proxy file for rendering).

4) For every video edit, VideoWave creates an audio proxy file in the Proxy Files location.  When the proxy file is finished  I save the production - enter a new production, then reload the saved production.  This will then cause VideoWave to access the proxy file.  If you listen to the proxy file in a different program, like VLC, the audio is corrupted and distorted.

5) Once reloaded - the audio for the file beyond around 7-10 minutes is corrupted.

6) Even more interesting is that if I delete the proxy file and reload the production, the sound is fine - until the proxy file is created and the production reloaded.

7) Once reloaded the audio is once again corrupt.

This issue didn't exist in NXT5 which is what I had before. I use originally recorded video and audio, so no copyrights are involved. Each time I split the video to edit, the sound gets worse and worse. I upgraded hoping to reduce the crashing issues. I wish I had done my homework and saw that NXT7 crashes, too. I need to find a way to fix this sound issue. Help!

[Mud]

I have the same issue.  Posted about it in March, moderators closed the discussion.  Went through about 4 stints with Corel tech support, remote access, reinstallations and they suggested I get a refund.  I can't believe they won't find the source of the issue and fix it.  No updated software available.  I have tried installing on 3 completely different computers plus a windows 7 and windows 10 virtual machine, all with the exact same issue so it is not computer related.

Any video file loads and previews fine in videowave.  However, the audio proxy files that videowave creates become corrupt as soon as you edit the video in videowave. 

I have successfully exported a few videos and even though the audio is corrupt in preview, the audio corrects itself (I assume the aproxy file is just used for videowave's editing and not actually used for creating the output)

NXT5 did not have this issue. 

I reverted back to NXT5 and I took a video, edited it and made a copy of the aproxy file and listened to it - No distortion, no buzzing in any audio player
Then reinstalled NXT7, took the same video, edited it and made a copy of the aproxy file and listened to it - Progressive distortion the further in the audio file you go

aproxy file excerpt - NXT5.wav

aproxy file excerpt - NXT7.wav

This is ridiculous. I recently purchased the software and when I burn DVD video I have the same problem. When I get about halfway thru the audio gets static and after a while u can't make out any of the audio. 

Apparently this problem has been going on for a couple of years. How is that possible. 

Please fix this problem!!!

[MysterC]

I had this one time from mp3's I had purchased from Amazon. It's not a drm issue. When the project was produced the music sounded like it was being digitized/distorted, but when you played just the clip sample it worked fine, and sometimes it would happen in the middle of a song, not the entire track.

One time I fixed it by opening the windows sound options (from the tray speaker icon) select <open sound settings> in the context menu \ then on the right "most" menu select Sound Control Panel \ click on your output/speakers, then click on configure, set whatever it is to stereo.  (not heaphones, not 5.1 or 7.1, not spatial or any other enhancements, and make sure your audio "Default Format" in the <properties>  isn't set too high, try like 24bit 48000hz at first and then lower it if needed)

Changing the windows output to stereo doesn't seem to affect the final DVD, but then again I don't have a super sound system on my TV/DVD player so what do I know.

The second time it happened I fixed with Cyberlink Power Director.

 

Good luck!!

For the record, I just purchased NXT8 Pro to see if they finally fixed this issue ...

It does the exact same thing!!!!  Corrupt aproxy files are still being created.

The audio in output files is ok, so the application is usable ...

Just a pain when editing / previewing your work.

As Mud above stated, I too had the same issue with NXT 7 VideoWave. So I upgraded to NXT 8 hoping it would be fixed. Nope. Audio still gets fuzzy when editing. I also got it once when copying a 2 hour VCR tape. However unlike Mud, my output files are also fuzzy. Even when I burn a DVD.

[Mud]

I just noticed today that there is a service pack update for NXT8 ----> creatornxt8_sp2.exe .  I installed it and it resolved the distorted audio on my machine instantly (I had to delete all existing a_proxy files first so new ones would get created)

Finally ... after wasting over $100 on NXT7 as it never worked properly.

Hopefully this fixes you up too DB56.

 

[Brendon]

Aha!!!      Thank you, Mud.   I've noted that for when we get an NXT 8 forum and the Gurus get NXT 8 to work with.

I guess it won't work on NXT 7  ?

 

edit:    Hoo!      SP2 is 260 MB, and holds 5,925 dif files.  It looks more like a major re-write than a minor fix.

Edited November 17, 2020 by Brendon

[LeeTXJD97]

I tried NXT 8 - the audio still ends up being distorted and fuzzy. 

The re-write didn't work.  I've attached the narration proxy file.  It is how it is rendered in the final video.

Thanks Lee.    Have you applied the SP2 and restarted everything?

 

 

[LeeTXJD97]

Yes.
