Audio missing in nested veggie!
I normally produce my wedding videos in chunks as separate projects, then combine the .veg files onto a timeline for final rendering. They’re mostly shot in DV with a DSR-250 or HVR-S270. In just the past few weeks, entire chunks of audio tend to go MIA once I combine these veggies on the timeline. Not for an entire .veg file, but a portion of it. It usually spans a single event, song or montage. Sometimes it’s a separately recorded .wma audio file, sometimes it’s an .mp3 song, sometimes it’s an entire audio channel of the video file. Sometimes it’s been normalized, sometimes not. It happens whether the project is created in V7 or V8, and whether it’s combined on a timeline in V7 or V8. Point is, there’s no rhyme or reason for these chunks of audio to randomly go missing. When I open the original project file, the audio is right there, happy as can be. My only workaround is to render each project separately and then combine the .avi files into, but that’s more than I should have to do. This has happened sporadically in the past, but now it happens every time. Any ideas?

Try to save the subproject under a different name. Delete the old subproject from the main one and import the new one. I had something similar happen to me and the renaming worked.

Thanks for the suggestion. I tried it, but it didn’t improve anything in this case.
Here’s what I’ve boiled it down to now. I created a project from scratch consisting only of the offending audio file. The audio file is both channels of a video clip shot in DV on a Sony DVR-S270 onto a CF card. It is but one of over 300 files, the rest of which seem to work fine. As a project consisting of just this one audio event, it previews and renders fine. As a .veg file dragged into a new project, it disappears, and I remain stumped. Any more thoughts?

OK, after some investigation, I’ve determined that this MAY NOT be occurring with different types of audio files. (Long story, but the way I record and edit audio made it easy for me to mistake an AVI’s audio stream for an indepently recorded audio file.) As it turns out, ALL audio streams from files recorded with my DVR-S270 (NOT my DSR-250 as far as I can find) onto a CF card are having this problem. The reason I didn’t spot this before is that the majority of my videos include multiple audio tracks including many independent audio events, so I could not at a glance see that the AVI audio streams were missing when placing veggies on a timeline, unless it was in a location where the AVI audio stream was the only audio event. Make sense?
So the problem is simple… I can edit and work with my AVI’s in a regular project, but when I put those .veg projects onto a timeline, the AVIs’ audio disappears. Any ideas now?
(The only thing I can think of is that when I first place the AVIs onto a timeline, instead of just building peaks like I’m used to pre-CF, it builds “audio proxy” files first, then builds peaks. So could it be that maybe these “proxy” files aren’t detectable within a .veg file on a timeline? And why do these “proxy files have to be created to begin with? What’s so different about these CF-AVI files vs. what I capture from a tape?)
