Thanks guys for your interest,
Lazlo that’s the way I do it with bitmap sequences, it’s when I import individual frames from these sequences for subsequent compositing, that the par is not set correctly.
jeditdv, the only little disk icon I can see on the properties dialogue of one of the bitmaps is one next to the ‘Stream’, is that the one you mean?
Also can one of you tell me why Vegas insists that par for D1 is 1.0926, when everywhere else it’s 1.0666666
Thank you again,
Alan
