I am using Windows 10 Home and I don't even know how to find the Windows build number.

And ok I will try the reset.

I suppose I wasn't all the way truthful when asking my question. I just rendered 10 videos. 6 of them had audio issues around 19 seconds in. Is there anything else that could cause this in Vegas Movie Studio?

Also thanks for taking the time to help me out. I really do appreciate it.

Presumably the six with issues played okay when previewing your timeline?

Yes, they did. My preview works perfectly and there is no lag. All other programs are closed when I render these videos. I have no problems until the videos are rendered. No extra effects on the audio.

Okay, we need to narrow this down.

1. Is there anything different with the source audio of the six problem projects compared to your others?
2. Try exporting just the project audio to a wav export. Check this plays okay then add it to an extra audio track in your project. Mute the original audio tracks and export as usual to see if this makes any difference.

1. To my knowledge, no. I rendered all of the MP3's and WAV's from FL Studio with the exact same settings for all 10 files. The only thing that would even come to mind is the loudness levels in FL Studio. I try export all the songs at -11 LUFS (Hopefully I said that correctly).

2. I apologize for my lack of understanding. When you say "Try exporting just the project audio to a wav export", do you mean just render the audio file to MP4 or WAV format?

I just solo'd the audio from the project rendered it as a WAV. The Movie Studio WAV version was clean with no problems. I took the clean WAV that was rendered in Movie Studio and used that as the audio instead of the original audio exported from FL Studio. I just rendered the video and had the same glitches. I'm hoping I did that correctly.

I just rendered the MP3 version of the same song and it had glitches in the same areas as the WAV version.

Then, I rendered the WAV audio from one of the four that rendered fine and it still came out fine. So maybe there is a difference somehow between the songs I rendered from FL Studio?

Playing a file is different to rendering. When rendering video editors dig into the file and occasionally errors can become apparent which aren't seen or heard when the file is just played. It would appear this could be happening here.

Do you have any audio editors (Sound Forge, Audacity etc) which you could use to convert the problem files into wav to see if that makes any difference.

I just downloaded Audacity. I used it to convert one of the problem MP3s to a WAV and then used that WAV in the Vegas Movie Studio project. I still got the same issues.

Can you post a screen capture of your timeline?

Absolutely Dot. Was there a specific area you wanted me to zoom in on?

@Randall-Collier Could you upload one of your problem audio files somewhere so we can download and play with. Such as Dropbox, Google Drive, OneDrive, etc.

I don't have MS15 installed now but can try on 16 and 17 both Platinum versions.

This link should have the rendered video as well as the Movie Studio file. Let me know if you have trouble downloading it. I want to be able to render the project file to a HD Youtube video.

@Randall-Collier I tried to download the file to try on my MSP15 but couldn't access it.

Cheers, Robbie

@Robbie I apologize. Try one more time I just changed the access on Google.

Thanks @Randall-Collier .  Are you able to share source MP3 and Image File that you used to create your MP4 so that we can try and replicate the result you are getting (the project vf files don’t include source media – just the project settings and links).

Initial observations.  I am experiencing the same audio drop outs you describe when playing your encoded MP4 in various media players.  However if I import that same same MP4 into MSP15 the audio plays fine with no dropouts, so all the audio information is actually included in your MP4 - just not being reproduced in the media players. If I then reencode your MP4 using the Magix AVC/AAC Internet HD 1080p 29.97fps option the resulting new MP4 file works in all my players with no dropouts, confirming that all the data is included in your MP4 (but why it drops out though I don’t know yet - maybe some sort of clipping issue?).  (Note Mediainfo reports your MP4 as 29.97 fps progressive not 60FPS as you mentioned in your OP).

Hopefully @EricLNZand @Former user will stick with uis here, çause they know way more than I about VMS :-).

Cheers, Robbie

@Robbie Thanks for taking the time try and dig into this issue with me. I really do appreciate it.I just added the source MP3 and the picture to the Google folder. Let me know if you can't access them.

Thanks again

It does the same thing at 58 seconds. There are some nasty digital hits I think cause the players to drop the level. QT plays it without dropping the audio, but has a nasty high frequency click.

@Former user yea and it's so crazy because I've never had an issue for the past year I've used VMS 15. I'm trying to understand what I started doing wrong. I dont know if this has anything to do with anything, but another issue I started having at the same time was that I couldn't directly upload my movies to Youtube. I'm not looking for a fix for this issue but I was mentioning it because maybe the issues are related somehow?

I think it is the original audio file that is a problem. It has digital errors.

You wouldn't happen to know anything I could do to solve that issue would you?

@Randall-Collier thanks for posting the source files.  I wasn’t able to reproduce your issue In MSP15 with renders using various encode options producing a clean MP4.  I do notice though that when zooming right in on the MP3 waveform a few of the peaks in the 19-20sec area have an extended “plateau” like they’ve been clipped. as mentioned in my previous post, reencoding your MP4 dis produce a file with no drop outs but othwe rthan watching out for those spikes I don't know what else to suggest.

Cheers, Robbie

Thanks so much. I appreciate you digging into that for me. I'll maybe try to find an alternative because I make tons of videos for my music and I need an easy solution that I know will work without extra work. Thanks so much again for really helping me out.

Take care
