Major Sound Glitch with "Infinite" Loudness!!!

Kevin-Cutshall wrote on 10/19/2022, 7:38 AM

Warning, the audio in the video will be loud. Beware if you have headphones.

I create gaming videos using Movie Studio 15.0, Build 157. Sometimes when I play a clip in the timeline. A very loud, very high speed, very high pitch set of "voices" play instead of the regular audio. It sounds like Alvin and the Chipmunks only much faster (see the video). It caused the master bus to indicate "infinite" volume. It only happens with gameplay footage. The voices are not from anywhere within the games. Sometimes the captured footage has zero character voices in it, so I'm not sure where the chipmunk voices are coming from. I do add narration to my videos, but it's usually in another part of the timeline at the point I encounter the voice.

I capture the footage with an ElGato HD60. The noises appear in random places on the timeline. Sometimes I'll watch a clip and it sounds normal, but then I'll watch it a second time, and the glitch happens. Once it happens, it stays there on that clip, even if I move it somewhere else. I've tried rendering the sound and putting it back in. Most of the time that does not work. The loud sound either stays, or is replaced by silence.

-It is unsafe. It practically blows my ears off and I never know when it's going to happen.

-The loudness is not shown visually on the audio track that on the timeline

-The number of occurrences is increasing. Several months ago it was happening about once a week. Now it's happening several times per project.

-I'm on Windows 10, 64 GB RAM, Ryzen 5900X, RTX 3070

Thanks in advance for your assistance.

Do you have a good anti-virus program installed? The reason I ask is that if the gameplay is sourced from the internet, who knows what "extras" might be included as a bonus.

I have whatever anti-virus comes packaged for Windows 10. The gameplay shown isn't sourced from the Internet. I played it on a PS2 console and captured it via laptop.

One thing I'll do is to extract the audio from the source and convert it to wav file.

Then in VMS mute the video and load that wav file.

Fay, I have been doing that, but it only works about 10% of the time. Usually the noise either carries over to the new file, or the audio becomes blank on it. Right now the glitch has decided to stop happening. I may record myself doing that process once it happens again. I'm hoping for a solution that prevents this noise from happening in the first place so I won't have to do extra renderings.

Share the mediainfo data of your captured footage :

Ok. When the glitch returns, I will try the mediainfo thing. Thanks.

It happened again. This product is unsafe to use! Below is the media file of the file. Here's a another video of it too: Note that the glitch starts off not being there. As part of my normal video making process, I will watch gameplay playback on the timeline, get the part I want to use, then move it to another part of the timeline to be with my narration. Then that's when the glitch happens (on the rare occasions it does happen). I actually took the high pitch sounds and slowed them down in Audacity, and guess what I heard? My own voice! It's me narrating. It's like the program is taking a clip from my narration audio, speeding it up, and then merging it with the game audio.

Bump. Let me know if there are any theories. I will have to switch to a different editing program if it's not resolved. Truthfully, this is only one of many issues I have with this program. It crashes a lot on me; about 5 times per project, and I lose a lot of work. The crashing has been happening for years, with different versions, and different computers.

I suspect RFI. Look for an open mic channel that has poor connections, poor shields, etc.
Using another video editor would be a good step to exclude hardware.

If you're shooting with an unbalanced microphone under a 69kV power distribution line where you can see a cell tower, you're probably screwed.
