Hi. I have been getting this weird issue in Vegas for the longest time now when pitch shifting some things. It can sometimes sync drift for no reason, and I don't even know why it happens. It's especially noticeable on longer videos, which is super annoying. I can't seem to get rid of it, no matter how much I tried. I tried changing the pitch attributes of it and sometimes it works, and sometimes it doesn't. One solution I found was to switch to the Classic setting, but it ruins some of the quality on the audio and doesn't sound smooth. If you want to reproduce this issue, here are some sets of pitches along with the attributes that causes the sync drift to happen.

- Elastique, Efficient, 0 and 3 side by side.

- Elastique, Pro, 0 and -2.5 side by side.

- Elastique, Pro, 0 and -0.69 side by side.

- Elastique, Efficient, 22 and 24 side by side.

Any idea on how I can fix this? Thanks!
