Hi Jerry,
I have three jpg sequences each about 150fms (imported the way you stated) aligned vertically on three tracks (I was planning to mask them individually) but as soon as I try to scrub the timeline, or do anything else in that region, Vegas crashes.
It wont render that region, either to the render sequence command or output a test m2v. If I set it render a longer m2v, it’ll freeze when it gets to that section. It seems to me like it’s trying to access the multiple files on the same disk simultaneously and panics.
I thought it may be some corruption of the jpgs but they seem perfect in every other application.
I’ve resorted to compositing this in AE but I should have thought Vegas would have done this easily. On second thoughts I wonder whether it would be worth trying a different bitmap format (eg tga or png)
Thanks for you interest and help
Alan
