Many video game capture tools support multiple audio inputs, and splitting them to different channels for ease of use later. when importing these files to vegas, it often causes severe issues. audio files will be scrambled, the two tracks switching between each other sporadically the longer the file goes on. also zooming the audio waveform shows bits that were not there prior to zooming. and I don't mean it's expanding, I mean the waveform was flat and now it's not. this even affects normalizing audio, as if you normalize the segment zoomed out and calculate the amount to gain then zoom in, the new audio that appears (chunks of the other stereo track) are clipped far beyond the bounds.
I am currently using Vegas Pro 15, but this issue also plagued Movie Studio 13/14 platinum when I used them.
then we zoom in a tick...
this is extremely sporadic and behavior varies each time I do it, if i relaunch vegas or even ctrl-Z in the same session, sometimes different segments will be messed up than before.
System is Windows 10 Pro October 2018 update, i3-8350k (stock clock speeds) 2*8GB DDR4-2400, GTX 1070.
Also worth mentioning, sometimes software will just crash when importing these files, and typically, the longer i try to edit these files, the worse it gets, typically within five minutes, playback previewing will stop working. the preview screen doesn't go black or anything, if i hit space, and the play button under the preview icon turns blue, but it's frozen. going to a different application window (like file explorer or a brower) then tabbing back to vegas and stopping then starting preview again sometimes fixes it.
