Hey, know this may be a blast from the past, but just now experiencing the same track matte "bug" in PE 7 that you and others discussed a few years ago.
Seemed to be the consensus then that what triggers the bug was either:
1. adding a video track before track 1, i.e., creating a new track 1, or
2. deleting empty (video?) tracks.
My question is does the track matte bug get triggered only if video tracks are deleted, or would it be triggered by deleting audio tracks as well? I have a completely separate soundtrack for my production and have no need for the audio associated with my video clips, so I've been deleting the audio tracks.
Thanks for your help,
Back a year, or two ago, Ed Macke posted of a Track Matte Key bug. Cannot recall the version that he was using, but I tested on PrE 4 (IIRC), and found that with a new Project, things worked perfectly, but with an older test Project, it did not. Again from memory, my test Project, while older, never had any Tracks (Audio, or Video) added, or deleted, but a lot of other work had been done in it, as I kept it around, well to test for others, or develop tutorials for an effect. That would lead me to believe that there are other triggers, as well. If I can find Ed's thread, I will post a link to it. Off to do some searching and reading.
Thanks again Bill.
All those threads reinforce the notion that at least PE4-PE7 have a bug that impacts the track matte effect, and I appear to be one of the bug's latest victims. Will probably start over with a new project and be sure not to delete any tracks or add any below track 1 either of which seems to be the most likely trigger for the bug. Don't think editing the track matte sequence in a separate project then importing it into the master project will be very practical, especially since there doesn't seem to be a way to export the clips used in the sequence from the master into the separate project.
As PrE does not have Sequences, like PrPro, there are only workarounds.
To Copy and Paste the material in one Project to another, one needs a Clipboard extender program, like ClipMate.
Or, one could create a Project, edit that, and then Export/Share to, say DV-AVI for an SD Project, and then Import that into the second Project.
Now, I have no idea if the Bug would be triggered by either of those methods.
