I recorded a video on my S24 ultra and it plays just fine on the phone as well as the Windows Media Player period but when I drag it from File Explorer to Vegas Pro 22 (Subscription), There is no audio except at the beginning of each MP4 audio file. There is a white box at the front portion of each audio file that is corrupted in some way. During that portion of the audio you can hear a loud hissing sound and then it stops and there's no audio. Most of the tracks have this white box although there is one or two that don't have the box but still make the sound. That white box appears to be a section where you can hear it and it correlates exactly with when the sound disappears it goes back to the regular looking portion of the track. The audio where you can actually hear normally does not have this box. This does not happen all the time only with certain videos.
There's a little more detail to this as I notice usually you can see the audio signature on the track until you play it and then all of a sudden there's a loud and then the audio disappears and there's just a flat line and no sound except at the beginning the hiss. It's almost like it's allows the play until the noise hits a certain amount of time at MAX dB, then hiding the deformity. But the audio is perfectly fine being played anywhere else. Interestingly this time I imported a bunch of tracks and about ¾’s of them have no audio signature. And you can hear the audio in the other 25%. Same device same recording time basically.
This started happening only with Vegas pro 22 and it doesn't happen with most of the MP4’s, Just certain ones and it's random. I haven't changed any audio settings in between or anything. It's like there's some kind of software glitch. I'd prefer not to reset everything because that's a real pain but i heard that might be one solution. I'd like to dig deeper and find the actual problem. Removing the import and doing it again doesn't work opening a new instance of Vegas Pro doesn't work.
Ignore Media Offline as the cause as if I click play it goes back online. Might be a symptom because usually my Media Timeline doesn't say that in production. But it keeps going back to that after playing. Very troubling.
