Noise at the end of a clip

Hi, sorry been poorly & in hospital for a mth so I've got some catching up to do,

This noise at the end of the audio was posted about several times last yr but did this ever get fixed or a reason found, ?

PS, forgot to say I dragged it onto the timeline initially from a Windows folder & the result with the noise is the picture above, but when I dragged that event to a lower track the noise went away🤷‍♂️

This describes a failure that is repeatable on my machine running Vegas Pro 21-108.

Executive Summary

A timeline full of full HD .mp4 files exhibits no sound abnormalities. When the same content rendered to pixel dimensions different from the project pixel dimensions is added to the timeline, the noise starts and affects all events on the timeline.

If you would like to try on your hardware, the source files can be downloaded from here:

These files were rendered from Vegas Pro 14-270 using the default templates.

The converse is also true.

A timeline full of UHD .mp4 files exhibits no sound abnormalities. When the same content rendered to pixel dimensions different from the project pixel dimensions is added to the timeline, the noise starts and affects all events on the timeline.

XAVC-S has an MP4 extension, too.

This is a BFD, folks.

Nice Videos John.

I have a feeling we may be on a different issue here. (I'm really sorry, pushed for time right now but can go into far more detail later on if it is of any use).

So basically, what I see is this. Every clip that I pull into Vegas has an extra little bit of the audio (in my case the dialogue track and main sum track at the end.)

[For ref I use OBS and record to 5 audio tracks. 1 is the full mix (used for streaming), 2 is dialogue only, 3 is audio / music, 4 is effects and stings, 5 is a bleep I set as marker ref.]

My procedure is to record at 4K (more details if required). Vegas project is set to exactly what my recorded files are.

As soon as I drag the recorded clips into Vegas (no stretching or moving just dragging them into a project), I see (and hear) this at the end of every clip. I double check the raw file and it does not exist in the file itself. Only when in Vegas. So, I don't need to do any rendering to see this issue.

What I do need to do is to take the time to figure out exactly what that little piece of audio is, it is not "recorded", but where it is coming from - it some part of the clip itself - (it is 100% not that I was still talking while stopping the recording). Then try some other settings in OBS too and see if I can figure it out. I realise that this is not really helpful until I have done that.

nb. Big Columbo fan here.

Please fix this asap, this noise issue is around for far to long; I can understand if it is hard to fix if it is hard to reproduce, but @john_dennis has given fine examples on how to. The added "farting" noise at the end is really not professional and degrades the Vegas product. Can we not get a hotfix for this?

We are working on it. We have been able to reproduce the problem for some time, but the fix for this has eluded us.

@Phil_P I record to Apple ProRes in OBS, though I rarely let anyone hear my voice anymore. So far, I haven't run out of disk space.
