Super Loud Blip Sound on Clip Start/End on occasion

shovel wrote on 7/10/2023, 2:25 PM

Does anyone know if there is a way to get around this bug in Vegas Pro 19 where it blasts a super loud blip at the start and end of clips on the timeline. It doesn't happen on every clip, but quite often. These are video clips that have no audio in them. It is being generated in Vegas. It took a screenshot of how loud the sound is. Its dead silent (since no sound in the clips) but during playback as soon as it goes over the start and end of a clip it blips

If i move the clip and put it back, sometimes it stops making the sound. So I can't really do anything to replicate it on purpose. Vegas just does it whenever it decides to. Its very annoying. It has done this since 19 was released all the way to now with the latest update. Makes me hesitant to spend any money on upgrading if this kind of ear damaging bug is going to still be present.

Very random and inconstant, V21B108.
Last second you see and hear it, go zooming and it's vanished.

But it doesn't happen with clips from my cameras.

I have posted several times about this issue as well.

Ditto. Ditto. Ditto. I also have sonic clicks at the beginning of audio edits - even with fading in (have to try to crossfade to solve). And there's also that thing where it will stop playing back the first part of certain clips at times (though it renders fine).

Go in and fade that out before the end of the clip - turn off everything on the track. Rerender. The artifact is still there.

Cross faded with an empty audio event. Rerender. Still there.

Faded the end into a -40dB 1K tone for a good half second. Rerender. Original artifact is still there.

Yea. Vegas is not in a good reliable working state. I won't be using it for anything more than simple quick video edits because of this (sadly). I do a lot of action animation work which requires a LOT of sound fx. I'm not about to commit to a huge project in this software when it means possibly having to fix hundreds of files on the timelines due to this ongoing bug.

It needs to be fixed asap or its the final nail on the coffin. I would have moved on way earlier, but its better to reach out first and see if they will fix things (same for any software). But two versions later, here we are still.
Mainly because this was a lot of money and I don't want to accept it was a poor investment.

Argh, I ran into this bug today when I had to re-render around 10 old projects in a different resolution. Every single f'ing time Vegas 20 would add loud audio spikes to the output files or mess up audio completely. So insanely frustrating. I get that Magix is focusing on cool new features to sell more product and broaden the user base but come on, fix these ancient infuriating bugs!

My workaround was to export the projects and then re-render them on a colleague's Mac, not my preference at all. But trimming the noises from the ends of clips wasn't a reliable workaround with V20 on a PC.

Please help: is there a reliable workaround that works with V20?

Render the audio separately on working version of VP or other DAW and mux in the good audio. A work-a-round at best....reliable, but not as easy as a single A/V render.

Which brings up the question, does the noise happen when rendering the project as audio only in VP-20. If that is the case, it would be faster to render and mux in the sound to the existing video.

Yes, unfortunately VP20 still messes up when rendering Audio only.

The attached picture shows the two original audio tracks above and the re-imported rendered audio track below. 100% repro across a good 20-something projects now. Sources are clean and render fine in Premiere. I think I'll open a ticket with Magix, whatever good that may do.

@cyro @shovel @Jessariah67 @Jody-Nasworthy @shovel @rraud @VEGASDerek

In Options / Preferences / File I/O tick "Enable legacy AVC decoding".

If you can live with compoundplug.dll doing the decoding of AVC-AAC in an mp4 wrapper, your audio problems will be gone for first generation renders. If you already have generation 2 through n renders that you might have to add back to a Vegas timeline, you're screwed and will have to resort to truncating the audio for each event before rendering again. If your video source requires the newer S04compoundplug.dll, then you're screwed until Magix fixes the audio decoding in that plugin.

Video at 5.

Edit: As promised Video at 5... err 6.

Well, that works for 3/4 of my scenarios - THANK YOU John!
Let's hope Magix will fix this soon, especially since it seems to be 100% reproducible etc.
