Vegas has Hidden My Audio Crossfades...
 

*See attached video*

I've just gone through an hour of footage and blended the sound between clips so that it seems to flow together. I've saved my project and gone back to it the day after, and Vegas seems to have hidden my crossfades, not just cosmetically but through playback as well! I am able to fix it usually by redragging the edge of the clip, at which time the crossfade magically re-appears (see video example i've attached)

Has some strange option been turned on? Currently I have automatic crossfading and event snapping turned on.

Very silly, not impressed :(

Did "quantize to frames" accidentally get turned off?

Also, what version of Vegas? (5, 6, 7, a, b, c, d, e????)

Looks like quantize to frames has been on. It sounds like it should be turned off though in this case judging by the option description, if it had anything to do with the problem.

Version 6.0d build 210

Sleeping on it didn't help either :(

Another video illustration of this odd problem. It looks like the clips have just been layered incorrectly somehow...I don't understand how Vegas can tolerate that kind of information though...would this even be possible to do under normal circumstances?

IMO, the ONLY time you want quantize to frames turned off is if you're doing serious audio editing or if you're trying to match sound sync between 2 or more cameras. Otherwise, leave it on as it makes sure that audio is properly lined up with a video frame, especially if you're splitting clips.

Going back to the clip you posted, I noticed something strange (to me anyway).
As soon as you start to drag the clip, the opposite end of the clips shifts as well. That's not normal behaviour. I've never seen it happen before and can't offer an explanation for it.

Can you post a copy of the VEG file somewhere so we can look at it? Is it possible you may have duplicated the events (i.e. and accidental CTRL-Drag - and, yes, I've done that before!)?

edit: removed vegas file

And no, I checked and there's only one copy of each audio event.

I did not have version 6.0d handy to try it in. However, I tried it in a newer version of Vegas and it opened just fine with the proper crossfades at area presented in the video clip above.

Hah, yeah I failed to realize that I had already gone through a fixed all the crossfades in the file I uploaded, so I guess I kind of ruined that oppourtunity.

If it happens again I'll post a proper vegas file. Any other suggestions for now though? Just seems like a glitch, I'm thinking I should just re-install and send Sony my documentation.
