sound glitch

mike77 wrote on 8/26/2022, 6:32 PM

My videos produced by Vegas 19/edit have a sound glitch.

I am building a video that includes my GoPro mp4 clip with sound and trying to overlay music over it.

Resulting video here

has an audio glitch around 39-40 seconds into the video.

Three comments about this:

a) building the same video using the same vf file on Vegas 14 works just fine

b) I used a 46-sec clip above to demonstrate the problem because if I cut down this clip to a smaller size the problem disappears.

c) I also tried uploading my original GoPro mp4 clip to youtube, then downloaded it and used downloaded Mp4 clip for my video - everything works fine.

Anyone can help with this issue ?

Thanks

Mike

@mike77 Hi, I've seen a few posts of sound glitches/noise towards the end of clips, i get a few clicks sometimes at the end, it either resolves itself by reloading the clip, sometimes doesn't tho & sometimes it seems to just go away by itself 🤷‍♂️😂, There doesn't seem to be a solid solution, some suggest it's SoundForge, or a partial end frame, on another forum the solution was to move the audio from an older type spinning drive to the main M,2/SSD (C) drive, but all the media i work with is on a fairly fast M.2 drive 🤷‍♂️,

Thank you for your recommendations Gid and John.

I tried another faster disk drive but it did not help. It also happens very consistently on two different computers so probably not just a fluke.

some suggest it's Sound Forge

That is not a symptom of the Sound Forge Audio Studio low latency driver issue,
